About tksheet

    tksheet is a Python tkinter table widget written in pure python.
    It is licensed under the MIT license.
    It works by using tkinter canvases and moving lines, text and rectangles around for only the visible portion of the table.
    If you are using a version of tksheet that is older than 7.0.0 then you will need the documentation here instead.
        In tksheet versions >= 7.0.2 the current version will be at the top of the file __init__.py.

Limitations

Some examples of things that are not possible with tksheet:

    Cell merging
    Cell text wrap
    Changing font for individual cells
    Different fonts for index and table
    Mouse drag copy cells
    Cell highlight borders
    At the present time the type hinting in tksheet is only meant to serve as a guide and not to be used with type checkers.

Installation and Requirements

tksheet is available through PyPi (Python package index) and can be installed by using Pip through the command line pip install tksheet

#To install using pip
pip install tksheet

#To update using pip
pip install tksheet --upgrade

Alternatively you can download the source code and inside the tksheet directory where the pyproject.toml file is located use the command line pip install -e .

    Versions < 7.0.0 require a Python version of 3.7 or higher.
    Versions >= 7.0.0 require a Python version of 3.8 or higher.

Basic Initialization

Like other tkinter widgets you need only the Sheet()s parent as an argument to initialize a Sheet() e.g.

sheet = Sheet(my_frame_widget)

    my_frame_widget would be replaced by whatever widget is your Sheet()s parent.

As an example, this is a tkinter program involving a Sheet() widget

from tksheet import Sheet
import tkinter as tk


class demo(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.grid_columnconfigure(0, weight = 1)
        self.grid_rowconfigure(0, weight = 1)
        self.frame = tk.Frame(self)
        self.frame.grid_columnconfigure(0, weight = 1)
        self.frame.grid_rowconfigure(0, weight = 1)
        self.sheet = Sheet(self.frame,
                           data = [[f"Row {r}, Column {c}\nnewline1\nnewline2" for c in range(50)] for r in range(500)])
        self.sheet.enable_bindings()
        self.frame.grid(row = 0, column = 0, sticky = "nswe")
        self.sheet.grid(row = 0, column = 0, sticky = "nswe")


app = demo()
app.mainloop()

Usage Examples

This is to demonstrate some of tksheets functionality.

    The functions which return the Sheet itself (have -> Sheet) can be chained with other Sheet functions.
    The functions which return a Span (have -> Span) can be chained with other Span functions.

from tksheet import Sheet, num2alpha
import tkinter as tk


class demo(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.grid_columnconfigure(0, weight=1)
        self.grid_rowconfigure(0, weight=1)
        self.frame = tk.Frame(self)
        self.frame.grid_columnconfigure(0, weight=1)
        self.frame.grid_rowconfigure(0, weight=1)

        # create an instance of Sheet()
        self.sheet = Sheet(
            # set the Sheets parent widget
            self.frame,
            # optional: set the Sheets data at initialization
            data=[[f"Row {r}, Column {c}\nnewline1\nnewline2" for c in range(20)] for r in range(100)],
            theme="light green",
            height=520,

        )

    name setting a name for the sheet is useful when you have multiple sheets and you need to determine which one an event came from.
    auto_resize_columns (int, None) if set as an int the columns will automatically resize to fit the width of the window, the int value being the minimum of each column in pixels.
    auto_resize_rows (int, None) if set as an int the rows will automatically resize to fit the height of the window, the int value being the minimum height of each row in pixels.
    startup_select selects cells, rows or columns at initialization by using a tuple e.g. (0, 0, "cells") for cell A0 or (0, 5, "rows") for rows 0 to 5.
    data_reference and data are essentially the same.
    row_index and index are the same, index takes priority, same as with headers and header.
    startup_select either (start row, end row, "rows"), (start column, end column, "rows") or (start row, start column, end row, end column, "cells"). The start/end row/column variables need to be ints.
    auto_resize_row_index either True, False or "empty".
        "empty" it will only automatically resize if the row index is empty.
        True it will always automatically resize.
        False it will never automatically resize.
    If show_selected_cells_border is False then the colors for table_selected_box_cells_fg/table_selected_box_rows_fg/table_selected_box_columns_fg will be used for the currently selected cells background.
    For help with treeview mode see here.

You can change most of these settings after initialization using the set_options() function.

    scrollbar_theme_inheritance and scrollbar_show_arrows will only work on Sheet() initialization, not with set_options()

Sheet Appearance
Sheet Colors

To change the colors of individual cells, rows or columns use the functions listed under highlighting cells.

For the colors of specific parts of the table such as gridlines and backgrounds use the function set_options(), keyword arguments specific to sheet colors are listed below. All the other set_options() arguments can be found here.

Use a tkinter color or a hex string e.g.

my_sheet_widget.set_options(table_bg="black")
my_sheet_widget.set_options(table_bg="#000000")
my_sheet_widget.set_options(horizontal_scroll_pressed_bg="red")

)

Otherwise you can change the theme using the below function.

change_theme(theme: str = "light blue", redraw: bool = True) -> Sheet

    theme (str) options (themes) are currently "light blue", "light green", "dark", "black", "dark blue" and "dark green".

Scrollbar Appearance

Scrollbar colors:

The above function and keyword arguments can be used to change the colors of the scroll bars.

Scrollbar relief, size, arrows, etc.

Some scroll bar style options can only be changed on Sheet() initialization, others can be changed whenever using set_options().

    Options that can only be set in the = Sheet(...) initialization:
        scrollbar_theme_inheritance: str = "default"
            This is which tkinter theme to inherit the new style from, changing the width of the scroll bar might not work with the "default" theme. If this is the case try using "clam" instead.
        scrollbar_show_arrows: bool
            When False the scroll bars arrow buttons on either end will be hidden, this may effect the width of the scroll bar.
    Options that can be set using set_options() also:
        vertical_scroll_borderwidth: int
        horizontal_scroll_borderwidth: int
        vertical_scroll_gripcount: int
        horizontal_scroll_gripcount: int
        vertical_scroll_arrowsize: str | int
        horizontal_scroll_arrowsize: str | int

Alternate Row Colors

For basic alternate row colors in the main table either:

    Use the Sheet() initialization keyword argument alternate_color (str) or
    Use the set_options() function with the keyword argument alternate_color

Examples:

set_options(alternate_color="#E2EAF4")

my_sheet = Sheet(parent, alternate_color="gray80")

Note that any cell, row or column highlights will display over alternate row colors.
Header and Index
Set the header

set_header_data(value: object, c: int | None | Iterator = None, redraw: bool = True) -> Sheet

    value (iterable, int, Any) if c is left as None then it attempts to set the whole header as the value (converting a generator to a list). If value is int it sets the header to display the row with that position.
    c (iterable, int, None) if both value and c are iterables it assumes c is an iterable of positions and value is an iterable of values and attempts to set each value to each position. If c is int it attempts to set the value at that position.

headers(
    newheaders: object = None,
    index: None | int = None,
    reset_col_positions: bool = False,
    show_headers_if_not_sheet: bool = True,
    redraw: bool = True,
) -> object

    Using an integer int for argument newheaders makes the sheet use that row as a header e.g. headers(0) means the first row will be used as a header (the first row will not be hidden in the sheet though), this is sort of equivalent to freezing the row.
    Leaving newheaders as None and using the index argument returns the existing header value in that index.
    Leaving all arguments as default e.g. headers() returns existing headers.

Set the index

set_index_data(value: object, r: int | None | Iterator = None, redraw: bool = True) -> Sheet

    value (iterable, int, Any) if r is left as None then it attempts to set the whole index as the value (converting a generator to a list). If value is int it sets the index to display the row with that position.
    r (iterable, int, None) if both value and r are iterables it assumes r is an iterable of positions and value is an iterable of values and attempts to set each value to each position. If r is int it attempts to set the value at that position.

row_index(
    newindex: object = None,
    index: None | int = None,
    reset_row_positions: bool = False,
    show_index_if_not_sheet: bool = True,
    redraw: bool = True,
) -> object

    Using an integer int for argument newindex makes the sheet use that column as an index e.g. row_index(0) means the first column will be used as an index (the first column will not be hidden in the sheet though), this is sort of equivalent to freezing the column.
    Leaving newindex as None and using the index argument returns the existing row index value in that index.
    Leaving all arguments as default e.g. row_index() returns the existing row index.

Bindings and Functionality
Enable table functionality and bindings

enable_bindings(*bindings)

    bindings (str) options are (rc stands for right click):
        "all"
        "single_select"
        "toggle_select"
        "drag_select"
            "select_all"
        "column_drag_and_drop" / "move_columns"
        "row_drag_and_drop" / "move_rows"
        "column_select"
        "row_select"
        "column_width_resize"
        "double_click_column_resize"
        "row_width_resize"
        "column_height_resize"
        "arrowkeys" # all arrowkeys including page up and down
        "up"
        "down"
        "left"
        "right"
        "prior" # page up
        "next" # page down
        "row_height_resize"
        "double_click_row_resize"
        "right_click_popup_menu"
        "rc_select"
        "rc_insert_column"
        "rc_delete_column"
        "rc_insert_row"
        "rc_delete_row"
        "ctrl_click_select" / "ctrl_select"
        "copy"
        "cut"
        "paste"
        "delete"
        "undo"
        "edit_cell"
        "edit_header"
        "edit_index"

Notes:

    You can change the Sheets key bindings for functionality such as copy, paste, up, down etc. Instructions can be found here.
    Control selection is NOT enabled with "all" and has to be specifically enabled.
    Header cell editing is NOT enabled with "all" and has to be specifically enabled.
    Index cell editing is NOT enabled with "all" and has to be specifically enabled.
    To allow table expansion when pasting data which doesn't fit in the table use either:
        paste_can_expand_x=True, paste_can_expand_y=True in sheet initialization arguments or the same keyword arguments with the function set_options().

Example:

    sheet.enable_bindings() to enable absolutely everything.

Disable table functionality and bindings

disable_bindings(*bindings)

Notes:

    Uses the same arguments as enable_bindings().

Bind specific table functionality

This function allows you to bind very specific table functionality to your own functions.

    If you want less specificity in event names you can also bind all sheet modifying events to a single function, see here.
    If you want to validate/modify user cell edits see here.

extra_bindings(
    bindings: str | list | tuple,
    func: Callable | None = None,
) -> Sheet

Notes:

    There are several ways to use this function:
        bindings as a str and func as either None or a function. Using None as an argument for func will effectively unbind the function.
            extra_bindings("edit_cell", func=my_function)
        bindings as an iterable of strs and func as either None or a function. Using None as an argument for func will effectively unbind the function.
            extra_bindings(["all_select_events", "copy", "cut"], func=my_function)
        bindings as an iterable of lists or tuples with length of two, e.g.
            extra_bindings([(binding, function), (binding, function), ...]) In this example you could also use None in the place of function to unbind the binding.
            In this case the arg func is totally ignored.
    For "end_..." events the bound function is run before the value is set.
    To unbind a function either set func argument to None or leave it as default e.g. extra_bindings("begin_copy") to unbind "begin_copy".

Parameters:

    bindings (str) options are:
        "begin_copy", "begin_ctrl_c"
        "ctrl_c", "end_copy", "end_ctrl_c", "copy"
        "begin_cut", "begin_ctrl_x"
        "ctrl_x", "end_cut", "end_ctrl_x", "cut"
        "begin_paste", "begin_ctrl_v"
        "ctrl_v", "end_paste", "end_ctrl_v", "paste"
        "begin_undo", "begin_ctrl_z"
        "ctrl_z", "end_undo", "end_ctrl_z", "undo"
        "begin_delete_key", "begin_delete"
        "delete_key", "end_delete", "end_delete_key", "delete"
        "begin_edit_cell", "begin_edit_table"
        "end_edit_cell", "edit_cell", "edit_table"
        "begin_edit_header"
        "end_edit_header", "edit_header"
        "begin_edit_index"
        "end_edit_index", "edit_index"
        "begin_row_index_drag_drop", "begin_move_rows"
        "row_index_drag_drop", "move_rows", "end_move_rows", "end_row_index_drag_drop"
        "begin_column_header_drag_drop", "begin_move_columns"
        "column_header_drag_drop", "move_columns", "end_move_columns", "end_column_header_drag_drop"
        "begin_rc_delete_row", "begin_delete_rows"
        "rc_delete_row", "end_rc_delete_row", "end_delete_rows", "delete_rows"
        "begin_rc_delete_column", "begin_delete_columns"
        "rc_delete_column", "end_rc_delete_column","end_delete_columns", "delete_columns"
        "begin_rc_insert_column", "begin_insert_column", "begin_insert_columns", "begin_add_column","begin_rc_add_column", "begin_add_columns"
        "rc_insert_column", "end_rc_insert_column", "end_insert_column", "end_insert_columns", "rc_add_column", "end_rc_add_column", "end_add_column", "end_add_columns"
        "begin_rc_insert_row", "begin_insert_row", "begin_insert_rows", "begin_rc_add_row", "begin_add_row", "begin_add_rows"
        "rc_insert_row", "end_rc_insert_row", "end_insert_row", "end_insert_rows", "rc_add_row", "end_rc_add_row", "end_add_row", "end_add_rows"
        "row_height_resize"
        "column_width_resize"
        "cell_select"
        "select_all"
        "row_select"
        "column_select"
        "drag_select_cells"
        "drag_select_rows"
        "drag_select_columns"
        "shift_cell_select"
        "shift_row_select"
        "shift_column_select"
        "ctrl_cell_select"
        "ctrl_row_select"
        "ctrl_column_select"
        "deselect"
        "all_select_events", "select", "selectevents", "select_events"
        "all_modified_events", "sheetmodified", "sheet_modified" "modified_events", "modified"
        "bind_all"
        "unbind_all"
    func argument is the function you want to send the binding event to.
    Using one of the following "all_modified_events", "sheetmodified", "sheet_modified", "modified_events", "modified" will make any insert, delete or cell edit including pastes and undos send an event to your function.
    For events "begin_move_columns"/"begin_move_rows" the point where columns/rows will be moved to will be accessible by the key named "value".
    For "begin_edit..." events the bound function must return a value to open the cell editor with, example here.

Event Data

Using extra_bindings() the function you bind needs to have at least one argument which will receive a dict. The values of which can be accessed by dot notation e.g. event.eventname or event.cells.table:

for (row, column), old_value in event.cells.table.items():
    print (f"R{row}", f"C{column}", "Old Value:", old_value)

It has the following layout and keys:

{
    "eventname": "",
    "sheetname": "",
    "cells": {
        "table": {},
        "header": {},

        "end_move_columns"
        "select"
        "resize"
    For events "begin_move_columns"/"begin_move_rows" the point where columns/rows will be moved to will be under the event_data key "value".
    Key ["sheetname"] is the name given to the sheet widget on initialization, useful if you have multiple sheets to determine which one emitted the event.
    Key ["cells"]["table"] if any table cells have been modified by cut, paste, delete, cell editors, dropdown boxes, check boxes, undo or redo this will be a dict with tuple keys of (data row index: int, data column index: int) and the values will be the cell values at that location prior to the change. The dict will be empty if no such changes have taken place.
    Key ["cells"]["header"] if any header cells have been modified by cell editors, dropdown boxes, check boxes, undo or redo this will be a dict with keys of int: data column index and the values will be the cell values at that location prior to the change. The dict will be empty if no such changes have taken place.
    Key ["cells"]["index"] if any index cells have been modified by cell editors, dropdown boxes, check boxes, undo or redo this will be a dict with keys of int: data row index and the values will be the cell values at that location prior to the change. The dict will be empty if no such changes have taken place.
    Key ["moved"]["rows"] if any rows have been moved by dragging and dropping or undoing/redoing of dragging and dropping rows this will be a dict with the following keys:
        {"data": {old data index: new data index, ...}, "displayed": {old displayed index: new displayed index, ...}}

            If no rows have been moved the dict under ["moved"]["rows"] will be empty.
            Note that if there are hidden rows the values for "data" will include all currently displayed row indexes and their new locations. If required and available, the values under "displayed" include only the directly moved rows, convert to data indexes using Sheet.data_r().
        For events "begin_move_rows" the point where rows will be moved to will be under the event_data key "value".
    Key ["moved"]["columns"] if any columns have been moved by dragging and dropping or undoing/redoing of dragging and dropping columns this will be a dict with the following keys:

            If no columns have been moved the dict under ["moved"]["columns"] will be empty.
            Note that if there are hidden columns the values for "data" will include all currently displayed column indexes and their new locations. If required and available, the values under "displayed" include only the directly moved columns, convert to data indexes using Sheet.data_c().
        For events "begin_move_columns" the point where columns will be moved to will be under the event_data key "value".
    Key ["added"]["rows"] if any rows have been added by the inbuilt popup menu insert rows or by a paste which expands the sheet then this will be a dict with the following keys:
        {"data_index": int, "displayed_index": int, "num": int, "displayed": []}
            "data_index" is an int representing the row where the rows were added in the data.
            "displayed_index" is an int representing the displayed table index where the rows were added (which will be different from the data index if there are hidden rows).
            "displayed" is simply a copied list of the Sheet()s displayed rows immediately prior to the change.
            If no rows have been added the dict will be empty.
    Key ["added"]["columns"] if any columns have been added by the inbuilt popup menu insert columns or by a paste which expands the sheet then this will be a dict with the following keys:

            "displayed_index" is an int representing the displayed table index where the columns were added (which will be different from the data index if there are hidden columns).
            "displayed" is simply a copied list of the Sheet()s displayed columns immediately prior to the change.
            If no columns have been added the dict will be empty.
    Key ["deleted"]["columns"] if any columns have been deleted by the inbuilt popup menu delete columns or by undoing a paste which added columns then this will be a dict. This dict will look like the following:
        {[column data index]: {[row data index]: cell value, [row data index]: cell value}, [column data index]: {...} ...}
        If no columns have been deleted then the dict value for ["deleted"]["columns"] will be empty.
    Key ["deleted"]["rows"] if any rows have been deleted by the inbuilt popup menu delete rows or by undoing a paste which added rows then this will be a dict. This dict will look like the following:
        {[row data index]: {[column data index]: cell value, [column data index]: cell value}, [row data index]: {...} ...}
        If no rows have been deleted then the dict value for ["deleted"]["rows"] will be empty.
    Key ["deleted"]["header"] if any header values have been deleted by the inbuilt popup menu delete columns or by undoing a paste which added columns and header values then this will be a dict. This dict will look like the following:
        {[column data index]: header cell value, [column data index]: header cell value, ...}

        If no columns have been deleted then the dict value for ["deleted"]["column_widths"] will be empty.
    Key ["deleted"]["row_heights"] if any rows have been deleted by the inbuilt popup menu delete rows or by undoing a paste which added rows then this will be a dict. This dict will look like the following:
        {[row data index]: row height, [row data index]: row height, ...}

    Key ["deleted"]["displayed_columns"] if any columns have been deleted by the inbuilt popup menu delete columns or by undoing a paste which added columns then this will be a list. This list stores the displayed columns (the columns that are showing when others are hidden) immediately prior to the change.
    Key ["deleted"]["displayed_rows"] if any rows have been deleted by the inbuilt popup menu delete rows or by undoing a paste which added rows then this will be a list. This list stores the displayed rows (the rows that are showing when others are hidden) immediately prior to the change.
    Key ["named_spans"] This dict serves as storage for the Sheet()s named spans. Each value in the dict is a pickled span object.
    Key ["options"] This serves as storage for the Sheet()s options such as highlights, formatting, alignments, dropdown boxes, check boxes etc. It is a dict where the values are the sheets internal cell/row/column options dicts.
    Key ["selection_boxes"] the value of this is all selection boxes on the sheet in the form of a dict as shown below:
        For every event except "select" events the selection boxes are those immediately prior to the modification, for "select" events they are the current selection boxes.
        The layout is always: "selection_boxes": {(start row, start column, up to but not including row, up to but not including column): selection box type}.
            The row/column indexes are ints and the selection box type is a str either "cells", "rows" or "columns".
        The dict will be empty if there is nothing selected.
    Key ["selected"] the value of this when there is something selected on the sheet is a namedtuple. The values of which can be found here.
        When nothing is selected or the event is not relevant to the currently selected box, such as a resize event it will be an empty tuple.
    Key ["being_selected"] if any selection box is in the process of being drawn by holding down mouse button 1 and dragging then this will be a tuple with the following layout:
        (start row, start column, up to but not including row, up to but not including column, selection box type).
            The selection box type is a str either "cells", "rows" or "columns".
        If no box is in the process of being created then this will be a an empty tuple.
        See here for an example.
    Key ["data"] is primarily used for paste and it will contain the pasted data if any.
    Key ["key"] - str - is primarily used for cell edit events where a key press has occurred. For "begin_edit..." events the value is the actual key which was pressed (or "??" for using the mouse to open a cell). It also might be one of the following for end edit events:
        "Return" - enter key.
        "FocusOut" - the editor or box lost focus, perhaps by mouse clicking elsewhere.
        "Tab" - tab key.
    Key ["value"] is used primarily by cell editing events. For "begin_edit..." events it's the value displayed in he text editor when it opens. For "end_edit..." events it's the value in the text editor when it was closed, for example by hitting Return. It also used by "begin_move_columns"/"begin_move_rows" - the point where columns/rows will be moved to will be under the event_data key "value".
    Key ["loc"] is for cell editing events to show the displayed (not data) coordinates of the event. It will be either:
        A tuple of (int displayed row index, int displayed column index) in the case of editing table cells.
        A single int in the case of editing index/header cells.
    Key ["row"] is for cell editing events to show the displayed (not data) row number int of the event. If the event was not a cell editing event or a header cell was edited the value will be None.
    Key ["column"] is for cell editing events to show the displayed (not data) column number int of the event. If the event was not a cell editing event or an index cell was edited the value will be None.
    Key ["resized"]["rows"] is for row height resizing events, it will be a dict with the following layout:
        {int displayed row index: {"old_size": old_height, "new_size": new_height}}.
        If no rows have been resized then the value for ["resized"]["rows"] will be an empty dict.
    Key ["resized"]["columns"] is for column width resizing events, it will be a dict with the following layout:
        {int displayed column index: {"old_size": old_width, "new_size": new_width}}.
        If no columns have been resized then the value for ["resized"]["columns"] will be an empty dict.
    Key ["widget"] will contain the widget which emitted the event, either the MainTable(), ColumnHeaders() or RowIndex() which are all tk.Canvas widgets.

Validate user cell edits

With this function you can validate or modify most user sheet edits, includes cut, paste, delete (including column/row clear), dropdown boxes and cell edits.

edit_validation(func: Callable | None = None) -> Sheet

Parameters:

    func (Callable, None) must either be a function which will receive a tksheet event dict which looks like this or None which unbinds the function.

Notes:

    If your bound function returns None then that specific cell edit will not be performed.
    For examples of this function see here and here.

Add commands to the in-built right click popup menu

popup_menu_add_command(
    label: str,
    func: Callable,
    table_menu: bool = True,
    index_menu: bool = True,
    header_menu: bool = True,
    empty_space_menu: bool = True,
) -> Sheet

Remove commands added using popup_menu_add_command from the in-built right click popup menu

popup_menu_del_command(label: str | None = None) -> Sheet

    If label is None then it removes all.

Enable or disable mousewheel, left click etc

basic_bindings(enable: bool = False) -> Sheet

These functions are links to the Sheets own functionality. Functions such as cut() rely on whatever is currently selected on the Sheet.

cut(event: object = None) -> Sheet
copy(event: object = None) -> Sheet
paste(event: object = None) -> Sheet
delete(event: object = None) -> Sheet
undo(event: object = None) -> Sheet
redo(event: object = None) -> Sheet
zoom_in() -> Sheet
zoom_out() -> Sheet

Get the last event data dict

@property
def event() -> EventDataDict

    e.g. last_event_data = sheet.event
    Will be empty EventDataDict if there is no last event.

Set focus to the Sheet

focus_set(
    canvas: Literal[
        "table",
        "header",
        "row_index",
        "index",
        "topleft",
        "top_left",
    ] = "table",
) -> Sheet

tkinter and tksheet Events
Sheet bind

    With the Sheet.bind() function you can bind things in the usual way you would in tkinter and they will bind to all the tksheet canvases.
    There are also the following special tksheet events you can bind:

Binding 	Usable with Sheet.event_generate()
"<<SheetModified>>" 	-
"<<SheetRedrawn>>" 	-
"<<SheetSelect>>" 	-
"<<Copy>>" 	X
"<<Cut>>" 	X
"<<Paste>>" 	X
"<<Delete>>" 	X
"<<Undo>>" 	X
"<<Redo>>" 	X
"<<SelectAll>>" 	X

bind(
    event: str,
    func: Callable,
    add: str | None = None,
)

Parameters:

    add may or may not work for various bindings depending on whether they are already in use by tksheet.
    Note that while a bound event after a paste/undo/redo might have the event name "edit_table" it also might have added/deleted rows/columns, refer to the docs on the event data dict for more information.
    event the emitted events are:
        "<<SheetModified>>" emitted whenever the sheet was modified by the end user by editing cells or adding or deleting rows/columns. The function you bind to this event must be able to receive a dict argument which will be the same as the event data dict but with less specific event names. The possible event names are listed below:
            "edit_table" when a user has cut, paste, delete or any cell edits including using dropdown boxes etc. in the table.
            "edit_index" when a user has edited a index cell.
            "edit_header" when a user has edited a header cell.
            "add_columns" when a user has inserted columns.
            "add_rows" when a user has inserted rows.
            "delete_columns" when a user has deleted columns.
            "delete_rows" when a user has deleted rows.
            "move_columns" when a user has dragged and dropped columns.
            "move_rows" when a user has dragged and dropped rows.
        "<<SheetRedrawn>>" emitted whenever the sheet GUI was refreshed (redrawn). The data for this event will be different than the usual event data, it is simply:
            {"sheetname": name of your sheet, "header": bool True if the header was redrawn, "row_index": bool True if the index was redrawn, "table": bool True if the the table was redrawn}
        "<<SheetSelect>>" encompasses all select events and emits the same event as "<<SheetModified>>" but with the event name: "select".
        "<<Copy>>" emitted when a Sheet copy e.g. <Control-c> was performed and will have the eventname "copy".
        "<<Cut>>"
        "<<Paste>>"
        "<<Delete>>" emitted when a Sheet delete key function was performed.
        "<<SelectAll>>"
        "<<Undo>>"
        "<<Redo>>"

Example:

# self.sheet_was_modified is your function
self.sheet.bind("<<SheetModified>>", self.sheet_was_modified)

Example for event_generate():

self.sheet.event_generate("<<Copy>>")

    Tells the sheet to run its copy function.

Sheet unbind

With this function you can unbind things you have bound using the bind() function.

unbind(binding: str) -> Sheet

Sheet Languages and Bindings

In this section are instructions to change some of tksheets in-built language and bindings:

    The in-built right click menu.
    The in-built functionality keybindings, such as copy, paste etc.

Changing right click menu labels

You can change the labels for tksheets in-built right click popup menu by using the set_options() function with any of the following keyword arguments:

edit_header_label
edit_header_accelerator
edit_index_label
edit_index_accelerator
edit_cell_label
edit_cell_accelerator
cut_label
cut_accelerator
cut_contents_label
cut_contents_accelerator
copy_label
copy_accelerator
copy_contents_label
copy_contents_accelerator
paste_label
paste_accelerator
delete_label
delete_accelerator
clear_contents_label
clear_contents_accelerator
delete_columns_label
delete_columns_accelerator
insert_columns_left_label
insert_columns_left_accelerator
insert_column_label
insert_column_accelerator
insert_columns_right_label
insert_columns_right_accelerator
delete_rows_label
delete_rows_accelerator
insert_rows_above_label
insert_rows_above_accelerator
insert_rows_below_label
insert_rows_below_accelerator
insert_row_label
insert_row_accelerator
select_all_label
select_all_accelerator
undo_label
undo_accelerator

Example:

# changing the copy label to the spanish for Copy
sheet.set_options(copy_label="Copiar")

Changing key bindings

You can change the bindings for tksheets in-built functionality such as cut, copy, paste by using the set_options() function with any the following keyword arguments:

copy_bindings
cut_bindings
paste_bindings
undo_bindings
redo_bindings
delete_bindings
select_all_bindings
tab_bindings
up_bindings
right_bindings
down_bindings
left_bindings
shift_up_bindings
shift_right_bindings
shift_down_bindings
shift_left_bindings
prior_bindings
next_bindings

The argument must be a list of tkinter binding strs. In the below example the binding for copy is changed to "<Control-e>" and "<Control-E>".

# changing the binding for copy
sheet.set_options(copy_bindings=["<Control-e>", "<Control-E>"])

The default values for these bindings can be found in the tksheet file sheet_options.py.
Key bindings for other languages

There is limited support in tkinter for keybindings in languages other than english, for example tkinters .bind() function doesn't cooperate with cyrillic characters.

There are ways around this however, see below for a limited example of how this might be achieved:

from __future__ import annotations

import tkinter as tk

from tksheet import Sheet


class demo(tk.Tk):
    def __init__(self) -> None:
        tk.Tk.__init__(self)
        self.grid_columnconfigure(0, weight=1)
        self.grid_rowconfigure(0, weight=1)
        self.sheet = Sheet(
            parent=self,
            data=[[f"{r} {c}" for c in range(5)] for r in range(5)],
        )
        self.sheet.enable_bindings()
        self.sheet.grid(row=0, column=0, sticky="nswe")
        self.bind_all("<Key>", self.any_key)

    def any_key(self, event: tk.Event) -> None:
        """
        Establish that the Control key is held down
        """
        ctrl = (event.state & 4 > 0)
        if not ctrl:
            return
        """
        From here you can use event.keycode and event.keysym to determine
        which key has been pressed along with Control
        """
        print(event.keycode)
        print(event.keysym)
        """
        If the keys are the ones you want to have bound to Sheet functionality
        You can then call the Sheets functionality using event_generate()
        For example:
        """
        # if the key is correct then:
        self.sheet.event_generate("<<Copy>>")


app = demo()
app.mainloop()

Span Objects

In tksheet versions > 7 there are functions which utilise an object named Span. These objects are a subclass of dict but with various additions and dot notation attribute access.

Spans basically represent an contiguous area of the sheet. They can be one of three kinds:

    "cell"
    "row"
    "column"

They can be used with some of the sheets functions such as data getting/setting and creation of things on the sheet such as dropdown boxes.

Spans store:

    A reference to the Sheet() they were created with.
    Variables which represent a particular range of cells and properties for accessing these ranges.
    Variables which represent options for those cells.
    Methods which can modify the above variables.
    Methods which can act upon the table using the above variables such as highlight, format, etc.

Whether cells, rows or columns are affected will depend on the spans kind.
Creating a span

You can create a span by:

    Using the span() function e.g. sheet.span("A1") represents the cell A1

or

    Using square brackets on a Sheet object e.g. sheet["A1"] represents the cell A1

Both methods return the created span object.

span(
    *key: CreateSpanTypes,
    type_: str = "",
    name: str = "",
    table: bool = True,
    index: bool = False,
    header: bool = False,
    tdisp: bool = False,
    idisp: bool = True,
    hdisp: bool = True,
    transposed: bool = False,
    ndim: int = 0,
    convert: object = None,
    undo: bool = False,
    emit_event: bool = False,
    widget: object = None,
    expand: None | str = None,
    formatter_options: dict | None = None,
    **kwargs,
) -> Span
"""
Create a span / get an existing span by name
Returns the created span
"""

Parameters:

    key you do not have to provide an argument for key, if no argument is provided then the span will be a full sheet span. Otherwise key can be the following types which are type hinted as CreateSpanTypes:
        None
        str e.g. sheet.span("A1:F1")
        int e.g. sheet.span(0)
        slice e.g. sheet.span(slice(0, 4))
        Sequence[int | None, int | None] representing a cell of row, column e.g. sheet.span(0, 0)
        Sequence[Sequence[int | None, int | None], Sequence[int | None, int | None]] representing sheet.span(start row, start column, up to but not including row, up to but not including column) e.g. sheet.span(0, 0, 2, 2)
        Span e.g sheet.span(another_span)
    type_ (str) must be either an empty string "" or one of the following: "format", "highlight", "dropdown", "checkbox", "readonly", "align".
    name (str) used for named spans or for identification. If no name is provided then a name is generated for the span which is based on an internal integer ticker and then converted to a string in the same way column names are.
    table (bool) when True will make all functions used with the span target the main table as well as the header/index if those are True.
    index (bool) when True will make all functions used with the span target the index as well as the table/header if those are True.
    header (bool) when True will make all functions used with the span target the header as well as the table/index if those are True.
    tdisp (bool) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the table, not underlying cell data.
    idisp (bool) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the index, not underlying cell data.
    hdisp (bool) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the header, not underlying cell data.
    transposed (bool) is used by data getting and setting functions that utilize spans. When True:
        Returned sublists from data getting functions will represent columns rather than rows.
        Data setting functions will assume that a single sequence is a column rather than row and that a list of lists is a list of columns rather than a list of rows.
    ndim (int) is used by data getting functions that utilize spans, it must be either 0 or 1 or 2.
        0 is the default setting which will make the return value vary based on what it is. For example if the gathered data is only a single cell it will return a value instead of a list of lists with a single list containing a single value. A single row will be a single list.
        1 will force the return of a single list as opposed to a list of lists.
        2 will force the return of a list of lists.
    convert (None, Callable) can be used to modify the data using a function before returning it. The data sent to the convert function will be as it was before normally returning (after ndim has potentially modified it).
    undo (bool) is used by data modifying functions that utilize spans. When True and if undo is enabled for the sheet then the end user will be able to undo/redo the modification.
    emit_event when True and when using data setting functions that utilize spans causes a "<<SheetModified>> event to occur if it has been bound, see here for more information on binding this event.
    widget (object) is the reference to the original sheet which created the span. This can be changed to a different sheet if required e.g. my_span.widget = new_sheet.
    expand (None, str) must be either None or:
        "table"/"both" expand the span both down and right from the span start to the ends of the table.
        "right" expand the span right to the end of the table x axis.
        "down" expand the span downwards to the bottom of the table y axis.
    formatter_options (dict, None) must be either None or dict. If providing a dict it must be the same structure as used in format functions, see here for more information. Used to turn the span into a format type span which:
        When using get_data() will format the returned data.
        When using set_data() will format the data being set but NOT create a new formatting rule on the sheet.
    **kwargs you can provide additional keyword arguments to the function for example those used in span.highlight() or span.dropdown() which are used when applying a named span to a table.

Notes:

    To create a named span see here.

Span creation syntax

When creating a span using the below methods:

    strs use excel syntax and the indexing rule of up to AND including.
    ints use python syntax and the indexing rule of up to but NOT including.

For example python index 0 as in [0] is the first whereas excel index 1 as in "A1" is the first.

If you need to convert python indexes into column letters you can use the function num2alpha importable from tksheet:

from tksheet import (
    Sheet,
    num2alpha as n2a,
)

# column index five as a letter
n2a(5)

Span properties

Spans have a few @property functions:

    span.kind
    span.rows
    span.columns

Get a spans kind

span.kind

    Returns either "cell", "row" or "column".

span = sheet.span("A1:C4")
print (span.kind)
# prints "cell"

span = sheet.span(":")
print (span.kind)
# prints "cell"

span = sheet.span("1:3")
print (span.kind)
# prints "row"

span = sheet.span("A:C")
print (span.kind)
# prints "column"

# after importing num2alpha from tksheet
print (sheet[num2alpha(0)].kind)
# prints "column"

Get span rows and columns

span.rows
span.columns

Returns a SpanRange object. The below examples are for span.rows but you can use span.columns for the spans columns exactly the same way.

# use as an iterator
span = sheet.span("A1:C4")
for row in span.rows:
    pass
# use as a reversed iterator
for row in reversed(span.rows):
    pass

# check row membership
span = sheet.span("A1:C4")
print (2 in span.rows)
# prints True

# check span.rows equality, also can do not equal
span = self.sheet["A1:C4"]
span2 = self.sheet["1:4"]
print (span.rows == span2.rows)
# prints True

# check len
span = self.sheet["A1:C4"]
print (len(span.rows))
# prints 4

Span methods

Spans have the following methods, all of which return the span object itself so you can chain the functions e.g. span.options(undo=True).clear().bg = "indianred1"
Modify a spans attributes

span.options(
    type_: str | None = None,
    name: str | None = None,
    table: bool | None = None,
    index: bool | None = None,
    header: bool | None = None,

    transposed: bool | None = None,
    ndim: int | None = None,
    convert: Callable | None = None,
    undo: bool | None = None,
    emit_event: bool | None = None,
    widget: object = None,
    expand: str | None = None,
    formatter_options: dict | None = None,
    **kwargs,
) -> Span

Note: that if None is used for any of the following parameters then that Spans attribute will be unchanged.

    type_ (str, None) if not None then must be either an empty string "" or one of the following: "format", "highlight", "dropdown", "checkbox", "readonly", "align".
    name (str, None) is used for named spans or for identification.
    table (bool, None) when True will make all functions used with the span target the main table as well as the header/index if those are True.
    index (bool, None) when True will make all functions used with the span target the index as well as the table/header if those are True.
    header (bool, None) when True will make all functions used with the span target the header as well as the table/index if those are True.
    tdisp (bool, None) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the table, not underlying cell data.
    idisp (bool, None) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the index, not underlying cell data.
    hdisp (bool, None) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the header, not underlying cell data.
    transposed (bool, None) is used by data getting and setting functions that utilize spans. When True:
        Returned sublists from data getting functions will represent columns rather than rows.
        Data setting functions will assume that a single sequence is a column rather than row and that a list of lists is a list of columns rather than a list of rows.
    ndim (int, None) is used by data getting functions that utilize spans, it must be either 0 or 1 or 2.
        0 is the default setting which will make the return value vary based on what it is. For example if the gathered data is only a single cell it will return a value instead of a list of lists with a single list containing a single value. A single row will be a single list.
        1 will force the return of a single list as opposed to a list of lists.
        2 will force the return of a list of lists.
    convert (Callable, None) can be used to modify the data using a function before returning it. The data sent to the convert function will be as it was before normally returning (after ndim has potentially modified it).
    undo (bool, None) is used by data modifying functions that utilize spans. When True and if undo is enabled for the sheet then the end user will be able to undo/redo the modification.
    emit_event (bool, None) is used by data modifying functions that utilize spans. When True causes a "<<SheetModified>> event to occur if it has been bound, see here for more information.
    widget (object) is the reference to the original sheet which created the span. This can be changed to a different sheet if required e.g. my_span.widget = new_sheet.
    expand (str, None) must be either None or:
        "table"/"both" expand the span both down and right from the span start to the ends of the table.
        "right" expand the span right to the end of the table x axis.
        "down" expand the span downwards to the bottom of the table y axis.
    formatter_options (dict, None) must be either None or dict. If providing a dict it must be the same structure as used in format functions, see here for more information. Used to turn the span into a format type span which:
        When using get_data() will format the returned data.
        When using set_data() will format the data being set but NOT create a new formatting rule on the sheet.
    **kwargs you can provide additional keyword arguments to the function for example those used in span.highlight() or span.dropdown() which are used when applying a named span to a table.
    This function returns the span instance itself (self).

# entire sheet
span = sheet["A1"].options(expand="both")

# column A
span = sheet["A1"].options(expand="down")

# row 0
span = sheet["A1"].options(
    expand="right",
    ndim=1, # to return a single list when getting data
)

All of a spans modifiable attributes are listed here:

    from_r (int) represents which row the span starts at, must be a positive int.
    from_c (int) represents which column the span starts at, must be a positive int.
    upto_r (int, None) represents which row the span ends at, must be a positive int or None. None means always up to and including the last row.
    upto_c (int, None) represents which column the span ends at, must be a positive int or None. None means always up to and including the last column.
    type_ (str) must be either an empty string "" or one of the following: "format", "highlight", "dropdown", "checkbox", "readonly", "align".
    name (str) used for named spans or for identification. If no name is provided then a name is generated for the span which is based on an internal integer ticker and then converted to a string in the same way column names are.
    table (bool) when True will make all functions used with the span target the main table as well as the header/index if those are True.
    index (bool) when True will make all functions used with the span target the index as well as the table/header if those are True.
    header (bool) when True will make all functions used with the span target the header as well as the table/index if those are True.
    tdisp (bool) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the table, not underlying cell data.
    idisp (bool) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the index, not underlying cell data.
    hdisp (bool) is used by data getting functions that utilize spans and when True the function retrieves screen displayed data for the header, not underlying cell data.
    transposed (bool) is used by data getting and setting functions that utilize spans. When True:
        Returned sublists from data getting functions will represent columns rather than rows.
        Data setting functions will assume that a single sequence is a column rather than row and that a list of lists is a list of columns rather than a list of rows.
    ndim (int) is used by data getting functions that utilize spans, it must be either 0 or 1 or 2.
        0 is the default setting which will make the return value vary based on what it is. For example if the gathered data is only a single cell it will return a value instead of a list of lists with a single list containing a single value. A single row will be a single list.
        1 will force the return of a single list as opposed to a list of lists.
        2 will force the return of a list of lists.
    convert (None, Callable) can be used to modify the data using a function before returning it. The data sent to the convert function will be as it was before normally returning (after ndim has potentially modified it).
    undo (bool) is used by data modifying functions that utilize spans. When True and if undo is enabled for the sheet then the end user will be able to undo/redo the modification.
    emit_event (bool) is used by data modifying functions that utilize spans. When True causes a "<<SheetModified>> event to occur if it has been bound, see here for more information.
    widget (object) is the reference to the original sheet which created the span. This can be changed to a different sheet if required e.g. my_span.widget = new_sheet.
    kwargs a dict containing keyword arguments relevant for functions such as span.highlight() or span.dropdown() which are used when applying a named span to a table.

If necessary you can also modify these attributes the same way you would an objects. e.g.

# span now takes in all columns, including A
span = self.sheet("A")
span.upto_c = None

# span now adds to sheets undo stack when using data modifying functions that use spans
span = self.sheet("A")
span.undo = True

Using a span to format data

Formats table data, see the help on formatting for more information. Note that using this function also creates a format rule for the affected table cells.

span.format(
    formatter_options: dict = {},
    formatter_class: object = None,
    redraw: bool = True,
    **kwargs,
) -> Span

Example:

# using square brackets
sheet[:].format(int_formatter())

# or instead using sheet.span()
sheet.span(":").format(int_formatter())

These examples show the formatting of the entire sheet (not including header and index) as int and creates a format rule for all currently existing cells. Named spans are required to create a rule for all future existing cells as well, for example those created by the end user inserting rows or columns.
Using a span to delete data format rules

Delete any currently existing format rules for parts of the table that are covered by the span. Should not be used where there are data formatting rules created by named spans, see Named spans for more information.

span.del_format() -> Span

Example:

span1 = sheet[2:4]
span1.format(float_formatter())
span1.del_format()

Using a span to create highlights

span.highlight(
    bg: bool | None | str = False,
    fg: bool | None | str = False,
    end: bool | None = None,
    overwrite: bool = False,
    redraw: bool = True,
) -> Span

There are two ways to create highlights using a span:

Method 1 example using .highlight():

# highlights column A background red, text color black
sheet["A"].highlight(bg="red", fg="black")

# the same but after having saved a span
my_span = sheet["A"]
my_span.highlight(bg="red", fg="black")

Method 2 example using .bg/.fg:

# highlights column A background red, text color black
sheet["A"].bg = "red"
sheet["A"].fg = "black"

# the same but after having saved a span
my_span = sheet["A"]
my_span.bg = "red"
my_span.fg = "black"

Using a span to delete highlights

Delete any currently existing highlights for parts of the sheet that are covered by the span. Should not be used where there are highlights created by named spans, see Named spans for more information.

span.dehighlight() -> Span

Example:

span1 = sheet[2:4].highlight(bg="red", fg="black")
span1.dehighlight()

Using a span to create dropdown boxes

Creates dropdown boxes for parts of the sheet that are covered by the span. For more information see here.

span.dropdown(
    values: list = [],
    set_value: object = None,
    state: str = "normal",
    redraw: bool = True,
    selection_function: Callable | None = None,
    modified_function: Callable | None = None,
    search_function: Callable = dropdown_search_function,
    validate_input: bool = True,
    text: None | str = None,
) -> Span

Example:

sheet["D"].dropdown(
    values=["on", "off"],
    set_value="off",
)

Using a span to delete dropdown boxes

Delete dropdown boxes for parts of the sheet that are covered by the span. Should not be used where there are dropdown box rules created by named spans, see Named spans for more information.

span.del_dropdown() -> Span

Example:

dropdown_span = sheet["D"].dropdown(values=["on", "off"],
                                    set_value="off")
dropdown_span.del_dropdown()

Using a span to create check boxes

Create check boxes for parts of the sheet that are covered by the span.

span.checkbox(
    edit_data: bool = True,
    checked: bool | None = None,
    state: str = "normal",
    redraw: bool = True,
    check_function: Callable | None = None,
    text: str = "",
) -> Span

Parameters:

    edit_data when True edits the underlying cell data to either checked if checked is a bool or tries to convert the existing cell data to a bool.
    checked is the initial creation value to set the box to, if None then and edit_data is True then it will try to convert the underlying cell data to a bool.
    state can be "normal" or "disabled". If "disabled" then color will be same as table grid lines, else it will be the cells text color.
    check_function can be used to trigger a function when the user clicks a checkbox.
    text displays text next to the checkbox in the cell, but will not be used as data, data will either be True or False.

Example:

sheet["D"].checkbox(
    checked=True,
    text="Switch",
)

Using a span to delete check boxes

Delete check boxes for parts of the sheet that are covered by the span. Should not be used where there are check box rules created by named spans, see Named spans for more information.

span.del_checkbox() -> Span

Example:

checkbox_span = sheet["D"].checkbox(checked=True,
                                    text="Switch")
checkbox_span.del_checkbox()

Using a span to set cells to read only

Create a readonly rule for parts of the table that are covered by the span.

span.readonly(readonly: bool = True) -> Span

    Using span.readonly(False) deletes any existing readonly rules for the span. Should not be used where there are readonly rules created by named spans, see Named spans for more information.

Using a span to create text alignment rules

Create a text alignment rule for parts of the sheet that are covered by the span.

span.align(
    align: str | None,
    redraw: bool = True,
) -> Span

    align (str, None) must be either:
        None - clears the alignment rule
        "c", "center", "centre"
        "w", "west", "left"
        "e", "east", "right"

Example:

sheet["D"].align("right")

There are two ways to create alignment rules using a span:

Method 1 example using .align():

# column D right text alignment
sheet["D"].align("right")

# the same but after having saved a span
my_span = sheet["D"]
my_span.align("right")

Method 2 example using .align = :

# column D right text alignment
sheet["D"].align = "right"

# the same but after having saved a span
my_span = sheet["D"]
my_span.align = "right"

Using a span to delete text alignment rules

Delete text alignment rules for parts of the sheet that are covered by the span. Should not be used where there are alignment rules created by named spans, see Named spans for more information.

span.del_align() -> Span

Example:

align_span = sheet["D"].align("right")
align_span.del_align()

Using a span to clear cells

Clear cell data from all cells that are covered by the span.

span.clear(
    undo: bool | None = None,
    emit_event: bool | None = None,
    redraw: bool = True,
) -> Span

Parameters:

    undo (bool, None) When True if undo is enabled for the end user they will be able to undo the clear change.
    emit_event when True causes a "<<SheetModified>> event to occur if it has been bound, see here for more information.

Example:

# clears column D
sheet["D"].clear()

Using a span to tag cells

Tag cells, rows or columns depending on the spans kind, more information on tags here.

tag(*tags) -> Span

Notes:

    If span.kind is "cell" then cells will be tagged, if it's a row span then rows will be and so for columns.

Example:

# tags rows 2, 3, 4 with "hello world"
sheet[2:5].tag("hello world")

Using a span to untag cells

Remove all tags from cells, rows or columns depending on the spans kind, more information on tags here.

untag() -> Span

Notes:

    If span.kind is "cell" then cells will be untagged, if it's a row span then rows will be and so for columns.

Example:

# tags rows 2, 3, 4 with "hello" and "bye"
sheet[2:5].tag("hello", "bye")

# removes both "hello" and "bye" tags from rows 2, 3, 4
sheet[2:5].untag()

Set the spans orientation

The attribute span.transposed (bool) is used by data getting and setting functions that utilize spans. When True: - Returned sublists from data getting functions will represent columns rather than rows. - Data setting functions will assume that a single sequence is a column rather than row and that a list of lists is a list of columns rather than a list of rows.

You can toggle the transpotition of the span by using:

span.transpose() -> Span

If the attribute is already True this makes it False and vice versa.

span = sheet["A:D"].transpose()
# this span is now transposed
print (span.transposed)
# prints True

span.transpose()
# this span is no longer transposed
print (span.transposed)
# prints False

Expand the spans area

Expand the spans area either all the way to the right (x axis) or all the way down (y axis) or both.

span.expand(direction: str = "both") -> Span

    direction (None, str) must be either None or:
        "table"/"both" expand the span both down and right from the span start to the ends of the table.
        "right" expand the span right to the end of the table x axis.
        "down" expand the span downwards to the bottom of the table y axis.

Named Spans

Named spans are like spans but with a type, some keyword arguments saved in span.kwargs and then created by using a Sheet() function. Like spans, named spans are also contiguous areas of the sheet.

Named spans can be used to:

    Create options (rules) for the sheet which will expand/contract when new cells are added/removed. For example if a user were to insert rows in the middle of some already highlighted rows:
        With ordinary row highlights the newly inserted rows would NOT be highlighted.
        With named span row highlights the newly inserted rows would also be highlighted.
    Quickly delete an existing option from the table whereas an ordinary span would not keep track of where the options have been moved.

Note that generally when a user moves rows/columns around the dimensions of the named span essentially move with either end of the span:

    The new start of the span will be wherever the start row/column moves.
    The new end of the span will be wherever the end row/column moves. The exceptions to this rule are when a span is expanded or has been created with Nones or the start of 0 and no end or end of None.

For the end user, when a span is just a single row/column (and is not expanded/unlimited) it cannot be expanded but it can be deleted if the row/column is deleted.
Creating a named span

For a span to become a named span it needs:

    One of the following type_s: "format", "highlight", "dropdown", "checkbox", "readonly", "align".
    Relevant keyword arguments e.g. if the type_ is "highlight" then arguments for sheet.highlight() found here.

After a span has the above items the following function has to be used to make it a named span and create the options on the sheet:

named_span(span: Span)
"""
Adds a named span to the sheet
Returns the span
"""

    span must be an existing span with:
        a name (a name is automatically generated upon span creation if one is not provided).
        a type_ as described above.
        keyword arguments as described above.

Examples of creating named spans:

# Will highlight rows 3 up to and including 5
span1 = self.sheet.span(
    "3:5",
    type_="highlight",
    bg="green",
    fg="black",
)
self.sheet.named_span(span1)

#  Will always keep the entire sheet formatted as `int` no matter how many rows/columns are inserted
span2 = self.sheet.span(
    ":",
    # you don't have to provide a `type_` when using the `formatter_kwargs` argument
    formatter_options=int_formatter(),
)
self.sheet.named_span(span2)

Deleting a named span

To delete a named span you simply have to provide the name.

del_named_span(name: str)

Example, creating and deleting a span:

# span covers the entire sheet
self.sheet.named_span(
    self.sheet.span(
        name="my highlight span",
        type_="highlight",
        bg="dark green",
        fg="#FFFFFF",
    )
)
self.sheet.del_named_span("my highlight span")

# ValueError is raised if name does not exist
self.sheet.del_named_span("this name doesnt exist")
# ValueError: Span 'this name doesnt exist' does not exist.

Other named span functions

Sets the Sheets internal dict of named spans:

set_named_spans(named_spans: None | dict = None) -> Sheet

    Using None deletes all existing named spans

Get an existing named span:

get_named_span(name: str) -> dict

Get all existing named spans:

get_named_spans() -> dict

Getting Sheet Data
Using a span to get sheet data

A Span object (more information here) is returned when using square brackets on a Sheet like so:

span = self.sheet["A1"]

You can also use sheet.span():

span = self.sheet.span("A1")

The above spans represent the cell A1 - row 0, column 0.

A reserved span attribute named data can then be used to retrieve the data for cell A1, example below:

span = self.sheet["A1"]
cell_a1_data = span.data

The data that is retrieved entirely depends on the area the span represents. You can also use span.value to the same effect.

There are certain other span attributes which have an impact on the data returned, explained below:

    table (bool) when True will make all functions used with the span target the main table as well as the header/index if those are True.
    index (bool) when True will make all functions used with the span target the index as well as the table/header if those are True.
    header (bool) when True will make all functions used with the span target the header as well as the table/index if those are True.
    tdisp (bool) when True the function retrieves screen displayed data for the table, not underlying cell data.
    idisp (bool) when True the function retrieves screen displayed data for the index, not underlying cell data.
    hdisp (bool) when True the function retrieves screen displayed data for the header, not underlying cell data.
    transposed (bool) is used by data getting and setting functions that utilize spans. When True:
        Returned sublists from data getting functions will represent columns rather than rows.
        Data setting functions will assume that a single sequence is a column rather than row and that a list of lists is a list of columns rather than a list of rows.
    ndim (int) is used by data getting functions that utilize spans, it must be either 0 or 1 or 2.
        0 is the default setting which will make the return value vary based on what it is. For example if the gathered data is only a single cell it will return a value instead of a list of lists with a single list containing a single value. A single row will be a single list.
        1 will force the return of a single list as opposed to a list of lists.
        2 will force the return of a list of lists.
    convert (None, Callable) can be used to modify the data using a function before returning it. The data sent to the convert function will be as it was before normally returning (after ndim has potentially modified it).
    widget (object) is the reference to the original sheet which created the span (this is the widget that data is retrieved from). This can be changed to a different sheet if required e.g. my_span.widget = new_sheet.

Some more complex examples of data retrieval:

"single cell"
cell_a1_data = self.sheet["A1"].data

"entire sheet including headers and index"
entire_sheet_data = self.sheet["A1"].expand().options(header=True, index=True).data

"header data, no table or index data"
# a list of displayed header cells
header_data = self.sheet["A:C"].options(table=False, header=True).data

# a header value
header_data = self.sheet["A"].options(table=False, hdisp=False, header=True).data

"index data, no table or header data"
# a list of displayed index cells
index_data = self.sheet[:3].options(table=False, index=True).data

# or using sheet.span() a list of displayed index cells
index_data = self.sheet.span(slice(None, 3), table=False, index=True).data

# a row index value
index_data = self.sheet[3].options(table=False, idisp=False, index=True).data

"sheet data as columns instead of rows, with actual header data"
sheet_data = self.sheet[:].transpose().options(hdisp=False, header=True).data

# or instead using sheet.span() with only kwargs
sheet_data = self.sheet.span(transposed=True, hdisp=False, header=True).data

There is also a Sheet() function for data retrieval (it is used internally by the above data getting methods):

sheet.get_data(
    *key: CreateSpanTypes,
) -> object

Examples:

data = self.sheet.get_data("A1")
data = self.sheet.get_data(0, 0, 3, 3)
data = self.sheet.get_data(
    self.sheet.span(":D", transposed=True)
)

Generate sheet rows one at a time

This function is useful if you need a lot of sheet data, and produces one row at a time (may save memory use in certain scenarios). It does not use spans.

yield_sheet_rows(
    get_displayed: bool = False,
    get_header: bool = False,
    get_index: bool = False,
    get_index_displayed: bool = True,
    get_header_displayed: bool = True,
    only_rows: int | Iterator[int] | None = None,
    only_columns: int | Iterator[int] | None = None,
) -> Iterator[list[object]]

Parameters:

    get_displayed (bool) if True it will return cell values as they are displayed on the screen. If False it will return any underlying data, for example if the cell is formatted.
    get_header (bool) if True it will return the header of the sheet even if there is not one.
    get_index (bool) if True it will return the index of the sheet even if there is not one.
    get_index_displayed (bool) if True it will return whatever index values are displayed on the screen, for example if there is a dropdown box with text set.
    get_header_displayed (bool) if True it will return whatever header values are displayed on the screen, for example if there is a dropdown box with text set.
    only_rows (None, iterable) with this argument you can supply an iterable of int row indexes in any order to be the only rows that are returned.
    only_columns (None, iterable) with this argument you can supply an iterable of int column indexes in any order to be the only columns that are returned.

Get table data, readonly

@property
data()

    e.g. self.sheet.data
    Doesn't include header or index data.

The name of the actual internal sheet data variable

.MT.data

    You can use this to directly modify or retrieve the main table's data e.g. cell_0_0 = my_sheet_name_here.MT.data[0][0] but only do so if you know what you're doing.

Sheet methods

Sheet objects also have some functions similar to lists. Note that these functions do not include the header or index.

Iterate over table rows:

for row in self.sheet:
    print (row)

# and in reverse
for row in reversed(self.sheet):
    print (row)

Check if the table has a particular value (membership):

# returns True or False
search_value = "the cell value I'm looking for"
print (search_value in self.sheet)

    Can also check if a row is in the sheet if a list is used.

Get the number of rows in the sheet

get_total_rows(include_index: bool = False) -> int

Get the number of columns in the sheet

get_total_columns(include_header: bool = False) -> int

Get a value for a particular cell if that cell was empty

get_value_for_empty_cell(
    r: int,
    c: int,
    r_ops: bool = True,
    c_ops: bool = True,
) -> object

    r_ops/c_ops when both are True it will take into account whatever cell/row/column options exist. When just r_ops is True it will take into account row options only and when just c_ops is True it will take into account column options only.

Setting Sheet Data

Fundamentally, there are two ways to set table data:

    Overwriting the entire table and setting the table data to a new object.
    Modifying the existing data.

Overwriting the table

set_sheet_data(
    data: list | tuple | None = None,
    reset_col_positions: bool = True,
    reset_row_positions: bool = True,
    redraw: bool = True,
    verify: bool = False,
    reset_highlights: bool = False,
    keep_formatting: bool = True,
    delete_options: bool = False,
) -> object

Parameters:

    data (list) has to be a list of lists for full functionality, for display only a list of tuples or a tuple of tuples will work.
    reset_col_positions and reset_row_positions (bool) when True will reset column widths and row heights.
    redraw (bool) refreshes the table after setting new data.
    verify (bool) goes through data and checks if it is a list of lists, will raise error if not, disabled by default.
    reset_highlights (bool) resets all table cell highlights.
    keep_formatting (bool) when True re-applies any prior formatting rules to the new data, if False all prior formatting rules are deleted.
    delete_options (bool) when True all table options such as dropdowns, check boxes, formatting, highlighting etc. are deleted.

Notes:

    This function does not impact the sheet header or index.

@data.setter
data(value: object)

Notes:

    Acts like setting an attribute e.g. sheet.data = [[1, 2, 3], [4, 5, 6]]
    Uses the set_sheet_data() function and its default arguments.

Reset all or specific sheet elements and attributes

reset(
    table: bool = True,
    header: bool = True,
    index: bool = True,
    row_heights: bool = True,
    column_widths: bool = True,
    cell_options: bool = True,
    undo_stack: bool = True,
    selections: bool = True,
    sheet_options: bool = False,
    redraw: bool = True,
) -> Sheet

Parameters:

    table when True resets the table to an empty list.
    header when True resets the header to an empty list.
    index when True resets the row index to an empty list.
    row_heights when True deletes all displayed row lines.
    column_widths when True deletes all displayed column lines.

    selections when True deletes all selection boxes.
    sheet_options when True resets all the sheets options such as colors, font, popup menu labels and many more to default, for a full list of what's reset see the file sheet_options.py.

Notes:

    This function could be useful when a whole new sheet needs to be loaded.

Modifying sheet data

A Span object (more information here) is returned when using square brackets on a Sheet like so:

span = self.sheet["A1"]

You can also use sheet.span():

span = self.sheet.span("A1")

The above span example represents the cell A1 - row 0, column 0. A reserved span attribute named data (you can also use .value) can then be used to modify sheet data starting from cell A1. example below:

span = self.sheet["A1"]
span.data = "new value for cell A1"

# or even shorter:
self.sheet["A1"].data = "new value for cell A1"

# or with sheet.span()
self.sheet.span("A1").data = "new value for cell A1"

If you provide a list or tuple it will set more than one cell, starting from the spans start cell. In the example below three cells are set in the first row, starting from cell B1:

self.sheet["B1"].data = ["row 0, column 1 new value (B1)",
                         "row 0, column 2 new value (C1)",
                         "row 0, column 3 new value (D1)"]

You can set data in column orientation with a transposed span:

self.sheet["B1"].transpose().data = ["row 0, column 1 new value (B1)",
                                     "row 1, column 1 new value (B2)",
                                     "row 2, column 1 new value (B3)"]

When setting data only a spans start cell is taken into account, the end cell is ignored. The example below demonstrates this, the spans end - "B1" is ignored and 4 cells get new values:

self.sheet["A1:B1"].data = ["A1 new val", "B1 new val", "C1 new val", "D1 new val"]

These are the span attributes which have an impact on the data set:

    table (bool) when True will make all functions used with the span target the main table as well as the header/index if those are True.
    index (bool) when True will make all functions used with the span target the index as well as the table/header if those are True.
    header (bool) when True will make all functions used with the span target the header as well as the table/index if those are True.
    transposed (bool) is used by data getting and setting functions that utilize spans. When True:
        Returned sublists from data getting functions will represent columns rather than rows.
        Data setting functions will assume that a single sequence is a column rather than row and that a list of lists is a list of columns rather than a list of rows.
    widget (object) is the reference to the original sheet which created the span (this is the widget that data is set to). This can be changed to a different sheet if required e.g. my_span.widget = new_sheet.

Highlighting Cells
Creating highlights
Using spans to create highlights

Span objects (more information here) can be used to highlight cells, rows, columns, the entire sheet, headers and the index.

You can use either of the following methods:

    Using a span method e.g. span.highlight() more information here.
    Using a sheet method e.g. sheet.highlight(Span)

Or if you need user inserted row/columns in the middle of highlight areas to also be highlighted you can use named spans, more information here.

Whether cells, rows or columns are highlighted depends on the kind of span.

highlight(
    *key: CreateSpanTypes,
    bg: bool | None | str = False,
    fg: bool | None | str = False,
    end: bool | None = None,
    overwrite: bool = False,
    redraw: bool = True,
) -> Span

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.
    bg and fg arguments use either a tkinter color or a hex str color.
    end (bool) is used for row highlighting where True makes the highlight go to the end of the Sheet window on the x axis.
    overwrite (bool) when True overwrites the any previous highlight for that cell/row/column, whereas False will only impact the keyword arguments used.
    Highlighting cells, rows or columns will also change the colors of dropdown boxes and check boxes.

Example:

# highlight cell - row 3, column 5
self.sheet.highlight(
    (3, 5),
    bg="dark green",
    fg="white",
)

# or

# same cells, background red, text color black
sheet[3, 5].bg = "red"
sheet[3, 5].fg = "black"

Other ways to create highlights

Cells

    row: int | Literal["all"] = 0,
    column: int | Literal["all"] = 0,
    cells: list[tuple[int, int]] = [],

    fg: bool | None | str = False,
    highlight_header: bool = True,
    redraw: bool = True,
    overwrite: bool = True,
) -> Sheet

Deleting highlights
Using spans to delete highlights

If the highlights were created by a named span then the named span must be deleted, more information here.

Otherwise you can use either of the following methods to delete/remove highlights:

    Using a span method e.g. span.dehighlight() more information here.
    Using a sheet method e.g. sheet.dehighlight(Span) details below:

dehighlight(
    *key: CreateSpanTypes,
    redraw: bool = True,
) -> Span

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.

Example:

# highlight column B
self.sheet.highlight(
    "B",
    bg="dark green",
    fg="white",
)

# dehighlight column B
self.sheet.dehighlight("B")

) -> Sheet

Columns

dehighlight_columns(
    columns: list[int] | Literal["all"] = [],
    redraw: bool = True,
) -> Sheet

All

dehighlight_all(
    cells: bool = True,
    rows: bool = True,
    columns: bool = True,
    header: bool = True,
    index: bool = True,
    redraw: bool = True,
) -> Sheet

Dropdown Boxes
Creating dropdown boxes

Span objects (more information here) can be used to create dropdown boxes for cells, rows, columns, the entire sheet, headers and the index.

You can use either of the following methods:

    Using a span method e.g. span.dropdown() more information here.
    Using a sheet method e.g. sheet.dropdown(Span)

Or if you need user inserted row/columns in the middle of areas with dropdown boxes to also have dropdown boxes you can use named spans, more information here.

Whether dropdown boxes are created for cells, rows or columns depends on the kind of span.

dropdown(
    *key: CreateSpanTypes,
    values: list = [],
    edit_data: bool = True,
    set_values: dict[tuple[int, int] | int, object] | None = None,
    set_value: object = None,
    state: str = "normal",
    redraw: bool = True,
    selection_function: Callable | None = None,
    modified_function: Callable | None = None,
    search_function: Callable = dropdown_search_function,
    validate_input: bool = True,
    text: None | str = None,
) -> Span

Notes:

    selection_function/modified_function (Callable, None) parameters require either None or a function. The function you use needs at least one argument because tksheet will send information to your function about the triggered dropdown.
    When a user selects an item from the dropdown box the sheet will set the underlying cells data to the selected item, to bind this event use either the selection_function argument or see the function extra_bindings() with binding "end_edit_cell" here.

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.
    values are the values to appear in a list view type interface when the dropdown box is open.
    edit_data when True makes edits in the table, header or index (depending on the span) based on set_values/set_value.
    set_values when combined with edit_data=True allows a dict to be provided of data coordinates (tuple[int, int] for a cell span or int for a row/column span) as keys and values to set the cell at that coordinate to.
        e.g. set_values={(0, 0): "new value for A1"}.
        The idea behind this parameter is that an entire column or row can have individual cell values and is not set to set_value alone.
    set_value when combined with edit_data=True sets every cell in the span to the value provided. If left as None and if set_values is also None then the topmost value from values will be used or if not values then "".
    state determines whether or not there is also an editable text window at the top of the dropdown box when it is open.
    redraw refreshes the sheet so the newly created box is visible.
    selection_function can be used to trigger a specific function when an item from the dropdown box is selected, if you are using the above extra_bindings() as well it will also be triggered but after this function. e.g. selection_function = my_function_name
    modified_function can be used to trigger a specific function when the state of the box is set to "normal" and there is an editable text window and a change of the text in that window has occurred. Note that this function occurs before the dropdown boxes search feature.
    search_function (None, callable) sets the function that will be used to search the dropdown boxes values upon a dropdown text editor modified event when the dropdowns state is normal. Set to None to disable the search feature or use your own function with the following keyword arguments: (search_for, data): and make it return an row number (e.g. select and see the first value would be 0) if positive and None if negative.
    validate_input (bool) when True will not allow cut, paste, delete or cell editor to input values to cell which are not in the dropdown boxes values.
    text (None, str) can be set to something other than None to always display over whatever value is in the cell, this is useful when you want to display a Header name over a dropdown box selection.

Example:

# create dropdown boxes in column "D"
self.sheet.dropdown(
    "D",
    values=[0, 1, 2, 3, 4],
)

Deleting dropdown boxes

If the dropdown boxes were created by a named span then the named span must be deleted, more information here.

Otherwise you can use either of the following methods to delete/remove dropdown boxes.

    Using a span method e.g. span.del_dropdown() more information here.
    Using a sheet method e.g. sheet.del_dropdown(Span) details below:

del_dropdown(
    *key: CreateSpanTypes,
    redraw: bool = True,
) -> Span

Check Boxes
Creating check boxes

Span objects (more information here) can be used to create check boxes for cells, rows, columns, the entire sheet, headers and the index.

You can use either of the following methods:

    Using a span method e.g. span.checkbox() more information here.
    Using a sheet method e.g. sheet.checkbox(Span)

Or if you need user inserted row/columns in the middle of areas with check boxes to also have check boxes you can use named spans, more information here.

Whether check boxes are created for cells, rows or columns depends on the kind of span.

checkbox(
    *key: CreateSpanTypes,
    edit_data: bool = True,
    checked: bool | None = None,
    state: str = "normal",
    redraw: bool = True,
    check_function: Callable | None = None,
    text: str = "",
) -> Span

Notes:

    check_function (Callable, None) requires either None or a function. The function you use needs at least one argument because when the checkbox is clicked it will send information to your function about the clicked checkbox.
    Use highlight_cells() or rows or columns to change the color of the checkbox.
    Check boxes are always left aligned despite any align settings.

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.
    edit_data when True edits the underlying cell data to either checked if checked is a bool or tries to convert the existing cell data to a bool.
    checked is the initial creation value to set the box to, if None then and edit_data is True then it will try to convert the underlying cell data to a bool.
    state can be "normal" or "disabled". If "disabled" then color will be same as table grid lines, else it will be the cells text color.
    check_function can be used to trigger a function when the user clicks a checkbox.
    text displays text next to the checkbox in the cell, but will not be used as data, data will either be True or False.

Example:

self.sheet.checkbox(
    "D",
    checked=True,
)

Deleting check boxes

If the check boxes were created by a named span then the named span must be deleted, more information here.

Otherwise you can use either of the following methods to delete/remove check boxes:

    Using a span method e.g. span.del_checkbox() more information here.
    Using a sheet method e.g. sheet.del_checkbox(Span) details below:

del_checkbox(
    *key: CreateSpanTypes,
    redraw: bool = True,
) -> Span

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.

Example:

# creating checkboxes in column D
self.sheet.checkbox(
    "D",
    checked=True,
)

# deleting checkboxes in column D
self.sheet.del_checkbox("D")

Set or toggle a check box

click_checkbox(
    *key: CreateSpanTypes,
    checked: bool | None = None,
    redraw: bool = True,
) -> Span

click_header_checkbox(c: int, checked: bool | None = None) -> Sheet

click_index_checkbox(r: int, checked: bool | None = None) -> Sheet

Get a dictionary of all check box dictionaries

get_checkboxes() -> dict

get_header_checkboxes() -> dict

get_index_checkboxes() -> dict

Data Formatting

By default tksheet stores all user inputted data as strings and while tksheet can store and display any datatype with a __str__() method this has some obvious limitations.

Data formatting aims to provide greater functionality when working with different datatypes and provide strict typing for the sheet. With formatting you can convert sheet data and user input to a specific datatype.

Additionally, formatting also provides a function for displaying data on the table GUI (as a rounded float for example) and logic for handling invalid and missing data.

tksheet has several basic built-in formatters and provides functionality for creating your own custom formats as well.

A demonstration of all the built-in and custom formatters can be found here.
Creation and deletion of data formatting rules
Creating a data format rule

Span objects (more information here) can be used to format data for cells, rows, columns and the entire sheet.

You can use either of the following methods:

    Using a span method e.g. span.format() more information here.
    Using a sheet method e.g. sheet.format(Span)

Or if you need user inserted row/columns in the middle of areas with data formatting to also be formatted you can use named spans, more information here.

Whether data is formatted for cells, rows or columns depends on the kind of span.

format(
    *key: CreateSpanTypes,
    formatter_options: dict = {},
    formatter_class: object = None,
    redraw: bool = True,
    **kwargs,
) -> Span

Notes:

    When applying multiple overlapping formats with e.g. a formatted cell which overlaps a formatted row, the priority is as follows:
        Cell formats first.
        Row formats second.
        Column formats third.
    Data formatting will effectively override validate_input = True on cells with dropdown boxes.
    When getting data take careful note of the get_displayed options, as these are the difference between getting the actual formatted data and what is simply displayed on the table GUI.

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.
    formatter_options (dict) a dictionary of keyword options/arguements to pass to the formatter, see here for information on what argument to use.
    formatter_class (class) in case you want to use a custom class to store functions and information as opposed to using the built-in methods.
    **kwargs any additional keyword options/arguements to pass to the formatter.

Deleting a data format rule

If the data format rule was created by a named span then the named span must be deleted, more information here.

Otherwise you can use either of the following methods to delete/remove data formatting rules:

    Using a span method e.g. span.del_format() more information here.
    Using a sheet method e.g. sheet.del_format(Span) details below:

del_format(
    *key: CreateSpanTypes,
    clear_values: bool = False,
    redraw: bool = True,
) -> Span

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.
    clear_values (bool) if true, all the cells covered by the span will have their values cleared.

Delete all formatting

del_all_formatting(clear_values: bool = False) -> Sheet

    clear_values (bool) if true, all the sheets cell values will be cleared.

Reapply formatting to entire sheet

reapply_formatting() -> Sheet

    Useful if you have manually changed the entire sheets data using sheet.MT.data = and want to reformat the sheet using any existing formatting you have set.

Check if a cell is formatted

formatted(r: int, c: int) -> dict

    If the cell is formatted function returns a dict with all the format keyword arguments. The dict will be empty if the cell is not formatted.

Formatters

In addition to the generic formatter, tksheet provides formatters for many different data types.

A basic example showing how formatting some columns as float might be done:

import tkinter as tk

from tksheet import (
    Sheet,
    float_formatter,
)
from tksheet import (
    num2alpha,
)


class demo(tk.Tk):
    def __init__(self):
        super().__init__()
        self.grid_columnconfigure(0, weight=1)
        self.grid_rowconfigure(0, weight=1)
        self.sheet = Sheet(
            self,
            data=[[f"{r}", f"{r}"] for r in range(5)],
            expand_sheet_if_paste_too_big=True,
            theme="dark blue",
        )
        """
        Format example
        """
        # some keyword arguments inside float_formatter()
        self.sheet.format(
            num2alpha(0), # column A
            formatter_options=float_formatter(
                decimals=1,
                nullable=True,
            ),
        )
        # some keyword arguments outside
        # of float_formatter() instead
        self.sheet.format(
            "B", # column B
            formatter_options=float_formatter(),
            decimals=3,
            nullable=False,
        )
        """
        Rest of code
        """
        self.sheet.grid(row=0, column=0, sticky="nswe")
        self.sheet.enable_bindings(
            "all",
            "ctrl_select",
            "edit_header",
            "edit_index",
        )


app = demo()
app.mainloop()

You can use any of the following formatters as an argument for the parameter formatter_options.

A full list of keyword arguments available to these formatters is shown here.
Int Formatter

The int_formatter is the basic configuration for a simple interger formatter.

int_formatter(
    datatypes: tuple[object] | object = int,
    format_function: Callable = to_int,
    to_str_function: Callable = to_str,
    invalid_value: object = "NaN",
    **kwargs,
) -> dict

Parameters:

    format_function (function) a function that takes a string and returns an int. By default, this is set to the in-built tksheet.to_int. This function will always convert float-likes to its floor, for example "5.9" will be converted to 5.
    to_str_function (function) By default, this is set to the in-built tksheet.to_str, which is a very basic function that will displace the default string representation of the value.

Example:

sheet.format_cell(0, 0, formatter_options = tksheet.int_formatter())

Float Formatter

The float_formatter is the basic configuration for a simple float formatter. It will always round float-likes to the specified number of decimal places, for example "5.999" will be converted to "6.0" if decimals = 1.

float_formatter(
    datatypes: tuple[object] | object = float,
    format_function: Callable = to_float,
    to_str_function: Callable = float_to_str,
    invalid_value: object = "NaN",
    decimals: int = 2,
    **kwargs
) -> dict

Parameters:

    format_function (function) a function that takes a string and returns a float. By default, this is set to the in-built tksheet.to_float.
    to_str_function (function) By default, this is set to the in-built tksheet.float_to_str, which will display the float to the specified number of decimal places.
    decimals (int, None) the number of decimal places to round to. Defaults to 2.

Example:

sheet.format_cell(0, 0, formatter_options = tksheet.float_formatter(decimals = None)) # A float formatter with maximum float() decimal places

Percentage Formatter

The percentage_formatter is the basic configuration for a simple percentage formatter. It will always round float-likes as a percentage to the specified number of decimal places, for example "5.999%" will be converted to "6.0%" if decimals = 1.

percentage_formatter(
    datatypes: tuple[object] | object = float,
    format_function: Callable = to_percentage,
    to_str_function: Callable = percentage_to_str,
    invalid_value: object = "NaN",
    decimals: int = 0,
    **kwargs,
) -> dict

Parameters:

    format_function (function) a function that takes a string and returns a float. By default, this is set to the in-built tksheet.to_percentage. This function will always convert percentages to their decimal equivalent, for example "5%" will be converted to 0.05.
    to_str_function (function) By default, this is set to the in-built tksheet.percentage_to_str, which will display the float as a percentage to the specified number of decimal places. For example, 0.05 will be displayed as "5.0%".
    decimals (int) the number of decimal places to round to. Defaults to 0.

Example:

sheet.format_cell(0, 0, formatter_options=tksheet.percentage_formatter(decimals=1)) # A percentage formatter with 1 decimal place

Note:

By default percentage_formatter() converts user entry 21 to 2100% and 21% to 21%. An example where 21 is converted to 21% instead is shown below:

# formats column A as percentage

# uses:
# format_function=alt_to_percentage
# to_str_function=alt_percentage_to_str
sheet.format(
    "A",
    formatter_options=tksheet.percentage_formatter(
        format_function=alt_to_percentage,
        to_str_function=alt_percentage_to_str,
    )
)

Bool Formatter

bool_formatter(
    datatypes: tuple[object] | object = bool,
    format_function: Callable = to_bool,
    to_str_function: Callable = bool_to_str,
    invalid_value: object = "NA",
    truthy: set = truthy,
    falsy: set = falsy,
    **kwargs,
) -> dict

Parameters:

    format_function (function) a function that takes a string and returns a bool. By default, this is set to the in-built tksheet.to_bool.
    to_str_function (function) By default, this is set to the in-built tksheet.bool_to_str, which will display the boolean as "True" or "False".
    truthy (set) a set of values that will be converted to True. Defaults to the in-built tksheet.truthy.
    falsy (set) a set of values that will be converted to False. Defaults to the in-built tksheet.falsy.

Example:

# A bool formatter with custom truthy and falsy values to account for aussie and kiwi slang
sheet.format_cell(0, 0, formatter_options = tksheet.bool_formatter(truthy = tksheet.truthy | {"nah yeah"}, falsy = tksheet.falsy | {"yeah nah"}))

Generic Formatter

formatter(
    datatypes: tuple[object] | object,
    format_function: Callable,
    to_str_function: Callable = to_str,
    invalid_value: object = "NaN",
    nullable: bool = True,
    pre_format_function: Callable | None = None,
    post_format_function: Callable | None = None,
    clipboard_function: Callable | None = None,
    **kwargs,
) -> dict

This is the generic formatter options interface. You can use this to create your own custom formatters. The following options are available.

Note that all these options can also be passed to the Sheet() format functions as keyword arguments and are available as attributes for all formatters.

You can also provide functions of your own creation for all the below arguments which take functions if you require.

    datatypes (list) a list of datatypes that the formatter will accept. For example, datatypes = [int, float] will accept integers and floats.
    format_function (function) a function that takes a string and returns a value of the desired datatype. For example, format_function = int will convert a string to an integer.
    to_str_function (function) a function that takes a value of the desired datatype and returns a string. This determines how the formatter displays its data on the table. For example, to_str_function = str will convert an integer to a string. Defaults to tksheet.to_str.
    invalid_value (any) the value to return if the input string is invalid. For example, invalid_value = "NA" will return "NA" if the input string is invalid.
    nullable (bool) if true, the formatter will accept None as a valid input.
    pre_format_function (function) a function that takes a input string and returns a string. This function is called before the format_function and can be used to modify the input string before it is converted to the desired datatype. This can be useful if you want to strip out unwanted characters or convert a string to a different format before converting it to the desired datatype.
    post_format_function (function) a function that takes a value which might not be of the desired datatype, e.g. None if the cell is nullable and empty and if successful returns a value of the desired datatype or if not successful returns the input value. This function is called after the format_function and can be used to modify the output value after it is converted to the desired datatype. This can be useful if you want to round a float for example.
    clipboard_function (function) a function that takes a value of the desired datatype and returns a string. This function is called when the cell value is copied to the clipboard. This can be useful if you want to convert a value to a different format before it is copied to the clipboard.
    **kwargs any additional keyword options/arguements to pass to the formatter. These keyword arguments will be passed to the format_function, to_str_function, and the clipboard_function. These can be useful if you want to specifiy any additional formatting options, such as the number of decimal places to round to.

Datetime Formatters and Designing Your Own Custom Formatters

tksheet is at the moment a dependency free library and so doesn't include a datetime parser as is.

You can however very easily make a datetime parser if you are willing to install a third-party package. Recommended are:

    dateparser
    dateutil

Both of these packages have a very comprehensive datetime parser which can be used to create a custom datetime formatter for tksheet.

Below is a simple example of how you might create a custom datetime formatter using the dateutil package.

from tksheet import *
from datetime import datetime, date
from dateutil.parser import parse

def to_local_datetime(dt, **kwargs):
    '''
    Our custom format_function, converts a string or a date to a datetime object in the local timezone.
    '''
    if isinstance(dt, datetime):
        pass # Do nothing
    elif isinstance(dt, date):
        dt = datetime(dt.year, dt.month, dt.day) # Always good to account for unexpected inputs
    else:
        try:
            dt = parser.parse(dt)
        except:
            raise ValueError(f"Could not parse {dt} as a datetime")
    if dt.tzinfo is None:
        dt = dt.replace(tzinfo = tzlocal()) # If no timezone is specified, assume local timezone
    dt = dt.astimezone(tzlocal()) # Convert to local timezone
    return dt

def datetime_to_str(dt, **kwargs):
    '''
    Our custom to_str_function, converts a datetime object to a string with a format that can be specfied in kwargs.
    '''
    return dt.strftime(kwargs['format'])

# Now we can create our custom formatter dictionary from the generic formatter interface in tksheet
datetime_formatter = formatter(datatypes = datetime,
                               format_function = to_local_datetime,
                               to_str_function = datetime_to_str,
                               invalid_value = "NaT",
                               format = "%d/%m/%Y %H:%M:%S",
                               )

# From here we can pass our datetime_formatter into sheet.format() or span.format() just like any other formatter

For those wanting even more customisation of their formatters you also have the option of creating a custom formatter class. This is a more advanced topic and is not covered here, but it's recommended to create a new class which is a subclass of the tksheet.Formatter class and overriding the methods you would like to customise. This custom class can then be passed into the format_cells() formatter_class argument.
Readonly Cells
Creating a readonly rule

Span objects (more information here) can be used to create readonly rules for cells, rows, columns, the entire sheet, headers and the index.

You can use either of the following methods:

    Using a span method e.g. span.readonly() more information here.
    Using a sheet method e.g. sheet.readonly(Span)

Or if you need user inserted row/columns in the middle of areas with a readonly rule to also have a readonly rule you can use named spans, more information here.

Whether cells, rows or columns are readonly depends on the kind of span.

readonly(
    *key: CreateSpanTypes,
    readonly: bool = True,
) -> Span

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.
    readonly (bool) True to create a rule and False to delete one created without the use of named spans.

Deleting a readonly rule

If the readonly rule was created by a named span then the named span must be deleted, more information here.

Otherwise you can use either of the following methods to delete/remove readonly rules:

    Using a span method e.g. span.readonly() with the keyword argument readonly=False more information here.
    Using a sheet method e.g. sheet.readonly(Span) with the keyword argument readonly=False example below:

# creating a readonly rule
self.sheet.readonly(
    self.sheet.span("A", header=True),
    readonly=True,
)

# deleting the readonly rule
self.sheet.readonly(
    self.sheet.span("A", header=True),
    readonly=False,
)

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.
    readonly (bool) True to create a rule and False to delete one created without the use of named spans.

Text Font and Alignment
Font

    Font arguments require a three tuple e.g. ("Arial", 12, "normal") or ("Arial", 12, "bold") or ("Arial", 12, "italic")
    The table and index currently share a font, it's not possible to change the index font separate from the table font.

Set the table and index font

font(
    newfont: tuple[str, int, str] | None = None,
    reset_row_positions: bool = True,
) -> tuple[str, int, str]

Set the header font

header_font(newfont: tuple[str, int, str] | None = None) -> tuple[str, int, str]

Text Alignment

There are functions to set the text alignment for specific cells/rows/columns and also functions to set the text alignment for a whole part of the sheet (table/index/header).

    Alignment argument (str) options are:
        "w", "west", "left"
        "e", "east", "right"
        "c", "center", "centre"

Unfortunately vertical alignment is not available.
Whole widget text alignment

Set the text alignment for the whole of the table (doesn't include index/header).

table_align(
    align: str = None,
    redraw: bool = True,
) -> str | Sheet

Set the text alignment for the whole of the header.

header_align(
    align: str = None,
    redraw: bool = True,
) -> str | Sheet

Set the text alignment for the whole of the index.

row_index_align(
    align: str = None,
    redraw: bool = True,
) -> str | Sheet

# can also use index_align() which behaves the same

Creating a specific cell row or column text alignment rule

The following function is for setting text alignment for specific cells, rows or columns in the table, header and index.

Span objects (more information here) can be used to create text alignment rules for cells, rows, columns, the entire sheet, headers and the index.

You can use either of the following methods:

    Using a span method e.g. span.align() more information here.
    Using a sheet method e.g. sheet.align(Span)

Or if you need user inserted row/columns in the middle of areas with an alignment rule to also have an alignment rule you can use named spans, more information here.

Whether cells, rows or columns are affected depends on the kind of span.

align(
    *key: CreateSpanTypes,
    align: str | None = None,
    redraw: bool = True,
) -> Span

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.
    align (str, None) must be one of the following:
        "w", "west", "left"
        "e", "east", "right"
        "c", "center", "centre"

Deleting a specific text alignment rule

If the text alignment rule was created by a named span then the named span must be deleted, more information here.

Otherwise you can use either of the following methods to delete/remove specific text alignment rules:

    Using a span method e.g. span.del_align() more information here.
    Using a sheet method e.g. sheet.del_align(Span) details below:

del_align(
    *key: CreateSpanTypes,
    redraw: bool = True,
) -> Span

Parameters:

    key (CreateSpanTypes) either a span or a type which can create a span. See here for more information on the types that can create a span.

Column text alignments:

get_column_alignments() -> dict

Getting Cell Properties

The below functions can be used to retrieve cell options/properties such as highlights, format, readonly etc.
Get table cell properties

All selected cell/box getting functions return or generate displayed cell coordinates.

    Displayed cell coordinates ignore hidden rows/columns when indexing cells.
    Data cell coordinates include hidden rows/columns in indexing cells.

Get the currently selected cell

This is always a single cell of displayed indices. If you have hidden rows or columns you can change the integers to data indices using the following functions:

    Change a row
    Change a column

get_currently_selected() -> tuple | Selected

Notes:

    Returns either:
        namedtuple of (row, column, type_, box, iid, fill_iid).
            type_ can be "rows", "columns" or "cells".
            box tuple[int, int, int, int] are the coordinates of the box that the currently selected box is attached to.
                (from row, from column, up to but not including row, up to but not including column).
            iid is the canvas item id of the currently selected box.
            fill_iid is the canvas item id of the box that the currently selected box is attached to.
        An empty tuple if nothing is selected.
    Can also use sheet.selected as shorter @property version of the function.

Example:

currently_selected = self.sheet.get_currently_selected()
if currently_selected:
    row = currently_selected.row
    column = currently_selected.column
    type_ = currently_selected.type_

if self.sheet.selected:

Row Heights and Column Widths
Auto resize column widths to fit the window

To enable auto resizing of columns to the Sheet window use set_options() with the keyword argument auto_resize_columns. This argument can either be an int or None. If set as an int the columns will automatically resize to fit the width of the window, the int value being the minimum of each column in pixels. If None it will disable the auto resizing. Example:

# auto resize columns, column minimum width set to 150 pixels
set_options(auto_resize_columns=150)

If set as an int the rows will automatically resize to fit the width of the window, the int value being the minimum of each row in pixels. If None it will disable the auto resizing. Example:

# auto resize rows, row minimum width set to 30 pixels
set_options(auto_resize_rows=30)

    allow_end: bool = True,
) -> int | None

Sheet control actions

For example: sheet.bind("<Control-B>", sheet.paste)

cut(event: object = None, validation: bool = True) -> None | EventDataDict
paste(event: object = None, validation: bool = True) -> None | EventDataDict
delete(event: object = None, validation: bool = True) -> None | EventDataDict
copy(event: object = None) -> None | EventDataDict
undo(event: object = None) -> None | EventDataDict
redo(event: object = None) -> None | EventDataDict

    validation (bool) when False disables any bound edit_validation() function from running.

Scroll Positions and Cell Visibility
Sync scroll positions between widgets

sync_scroll(widget: object) -> Sheet

    Sync scroll positions between Sheets, may or may not work with other widgets. Uses scrollbar positions.

Syncing two sheets:

self.sheet1.sync_scroll(self.sheet2)

Syncing three sheets:

# syncs sheet 1 and 2 between each other
self.sheet1.sync_scroll(self.sheet2)

# syncs sheet 1 and 3 between each other
self.sheet1.sync_scroll(self.sheet3)

# syncs sheet 2 and 3 between each other
self.sheet2.sync_scroll(self.sheet3)

Unsync scroll positions between widgets

unsync_scroll(widget: object = None) -> Sheet

    Leaving widget as None unsyncs all previously synced widgets.

See or scroll to a specific cell on the sheet

see(
    row: int = 0,
    column: int = 0,
    keep_yscroll: bool = False,
    keep_xscroll: bool = False,
    bottom_right_corner: bool = False,
    check_cell_visibility: bool = True,
    redraw: bool = True,
) -> Sheet

Check if a cell has any part of it visible

cell_visible(r: int, c: int) -> bool

Check if a cell is totally visible

cell_completely_visible(r: int, c: int, seperate_axes: bool = False) -> bool

    separate_axes returns tuple of bools e.g. (cell y axis is visible, cell x axis is visible)

set_xview(position: None | float = None, option: str = "moveto") -> Sheet | tuple[float, float]

Notes:

    If position is None then tuple[float, float] of main table xview() is returned.
    xview and xview_moveto have the same behaviour.

set_yview(position: None | float = None, option: str = "moveto") -> Sheet | tuple[float, float]

    If position is None then tuple[float, float] of main table yview() is returned.
    yview and yview_moveto have the same behaviour.

get_xview() -> tuple[float, float]

get_yview() -> tuple[float, float]

set_view(x_args: [str, float], y_args: [str, float]) -> Sheet

Hiding Columns

Note that once you have hidden columns you can use the function displayed_column_to_data(column) to retrieve a column data index from a displayed index.
Display only certain columns

display_columns(
    columns: None | Literal["all"] | Iterator[int] = None,
    all_columns_displayed: None | bool = None,
    reset_col_positions: bool = True,
    refresh: bool = False,
    redraw: bool = False,
    deselect_all: bool = True,
    **kwargs,
) -> list[int] | None

Parameters:

    columns (int, iterable, "all") are the columns to be displayed, omit the columns to be hidden.
    Use argument True with all_columns_displayed to display all columns, use False to display only the columns you've set using the columns arg.
    You can also use the keyword argument all_displayed instead of all_columns_displayed.

Examples:

# display all columns
self.sheet.display_columns("all")

# displaying specific columns only
self.sheet.display_columns([2, 4, 7], all_displayed = False)

Get all columns displayed boolean

Get the bool

@property
all_columns()

    e.g. get_all_columns_displayed = sheet.all_columns.

Set the bool

@all_columns.setter
all_columns(a: bool)

e.g. sheet.all_columns = True.

all_columns_displayed(a: bool | None = None) -> bool

    a (bool, None) Either set by using bool or get by leaving None e.g. all_columns_displayed().

Hide specific columns

hide_columns(
    columns: int | set | Iterator[int] = set(),
    redraw: bool = True,
    deselect_all: bool = True,
    data_indexes: bool = False,
) -> Sheet

Parameters:

    NOTE: columns (int) by default uses displayed column indexes, not data indexes. In other words the indexes of the columns displayed on the screen are the ones that are hidden, this is useful when used in conjunction with get_selected_columns().
    data_indexes when False it makes the columns parameter indexes represent displayed columns and not the underlying Sheet data columns. When True the indexes represent data indexes.

Example:

columns_to_hide = set(sheet.data_c(c) for c in sheet.get_selected_columns())
sheet.hide_columns(
    columns_to_hide,
    data_indexes=True,
)

Unhide specific columns

show_columns(
    columns: int | Iterator[int],
    redraw: bool = True,
    deselect_all: bool = True,
) -> Sheet

Parameters:

    NOTE: columns (int) uses data column indexes, not displayed indexes. In other words the indexes of the columns which represent the underlying data are shown.

Notes:

    Will return if all columns are currently displayed (Sheet.all_columns).

Example:

# converting displayed column indexes to data indexes using data_c(c)
columns = set(sheet.data_c(c) for c in sheet.get_selected_columns())

# hiding columns
sheet.hide_columns(
    columns,
    data_indexes=True,
)

# showing them again
sheet.show_columns(columns)

Displayed column index to data

Convert a displayed column index to a data index. If the internal all_columns_displayed attribute is True then it will simply return the provided argument.

displayed_column_to_data(c)
data_c(c)

Get currently displayed columns

@property
displayed_columns() -> list[int]

    e.g. columns = sheet.displayed_columns

Hiding Rows

Note that once you have hidden rows you can use the function displayed_row_to_data(row) to retrieve a row data index from a displayed index.
Display only certain rows

display_rows(
    rows: None | Literal["all"] | Iterator[int] = None,
    all_rows_displayed: None | bool = None,
    reset_row_positions: bool = True,
    refresh: bool = False,
    redraw: bool = False,
    deselect_all: bool = True,
    **kwargs,
) -> list[int] | None

Parameters:

    rows (int, iterable, "all") are the rows to be displayed, omit the rows to be hidden.
    Use argument True with all_rows_displayed to display all rows, use False to display only the rows you've set using the rows arg.
    You can also use the keyword argument all_displayed instead of all_rows_displayed.

Examples:

    An example of row filtering using this function can be found here.
    More examples below:

# display all rows
self.sheet.display_rows("all")

# display specific rows only
self.sheet.display_rows([2, 4, 7], all_displayed = False)

Hide specific rows

hide_rows(
    rows: int | set | Iterator[int] = set(),
    redraw: bool = True,
    deselect_all: bool = True,
    data_indexes: bool = False,
) -> Sheet

Parameters:

    NOTE: rows (int) by default uses displayed row indexes, not data indexes. In other words the indexes of the rows displayed on the screen are the ones that are hidden, this is useful when used in conjunction with get_selected_rows().
    data_indexes when False it makes the rows parameter indexes represent displayed rows and not the underlying Sheet data rows. When True the indexes represent data indexes.

Example:

rows_to_hide = set(sheet.data_r(r) for r in sheet.get_selected_rows())
sheet.hide_rows(
    rows_to_hide,
    data_indexes=True,
)

Unhide specific rows

show_rows(
    rows: int | Iterator[int],
    redraw: bool = True,
    deselect_all: bool = True,
) -> Sheet

Parameters:

    NOTE: rows (int) uses data row indexes, not displayed indexes. In other words the indexes of the rows which represent the underlying data are shown.

Notes:

    Will return if all rows are currently displayed (Sheet.all_rows).

Example:

# converting displayed row indexes to data indexes using data_r(r)
rows = set(sheet.data_r(r) for r in sheet.get_selected_rows())

# hiding rows
sheet.hide_rows(
    rows,
    data_indexes=True,
)

# showing them again
sheet.show_rows(rows)

Get or set the all rows displayed boolean

Get the bool

@property
all_rows()

    e.g. get_all_rows_displayed = sheet.all_rows.

@all_rows.setter
all_rows(a: bool)

e.g. sheet.all_rows = True.

all_rows_displayed(a: bool | None = None) -> bool

    a (bool, None) Either set by using bool or get by leaving None e.g. all_rows_displayed().

Displayed row index to data

Convert a displayed row index to a data index. If the internal all_rows_displayed attribute is True then it will simply return the provided argument.

displayed_row_to_data(r)
data_r(r)

Get currently displayed rows

@property
displayed_rows() -> list[int]

    e.g. rows = sheet.displayed_rows

Hiding Sheet Elements

        "top_left",
        "x_scrollbar",
        "y_scrollbar",
    ] = "all",
) -> Sheet

    canvas (str) options are all, row_index, header, top_left, x_scrollbar, y_scrollbar
        all hides the entire table and is the default.

Show parts of the Sheet or all of it

show(
    canvas: Literal[
        "all",
        "row_index",
        "header",
        "top_left",
        "x_scrollbar",
        "y_scrollbar",
    ] = "all",
) -> Sheet

    canvas (str) options are all, row_index, header, top_left, x_scrollbar, y_scrollbar
        all shows the entire table and is the default.

Sheet Height and Width
Modify widget height and width in pixels

height_and_width(
    height: int | None = None,
    width: int | None = None,
) -> Sheet

    height (int, None) set a height in pixels.
    width (int, None) set a width in pixels. If both arguments are None then table will reset to default tkinter canvas dimensions.

get_frame_y(y: int) -> int

    Adds the height of the Sheets header to a y position.

get_frame_x(x: int) -> int

    Adds the width of the Sheets index to an x position.

Cell Text Editor
Open the currently selected cell in the main table

open_cell(ignore_existing_editor: bool = True) -> Sheet

    Function utilises the currently selected cell in the main table, even if a column/row is selected, to open a non selected cell first use set_currently_selected() to set the cell to open.

Open the currently selected cell but in the header

open_header_cell(ignore_existing_editor: bool = True) -> Sheet

    Also uses currently selected cell, which you can set with set_currently_selected().

Open the currently selected cell but in the index

open_index_cell(ignore_existing_editor: bool = True) -> Sheet

    Also uses currently selected cell, which you can set with set_currently_selected().

Set the cell text editor value if it is open

    text: str = "",
) -> Sheet

Index:

set_index_text_editor_value(
    text: str = "",

Treeview Mode

tksheet has a treeview mode which behaves similarly to the ttk treeview widget, it is not a drop in replacement for it though.
Treeview limitations and warnings

There are some key limitations to the treeview mode, most have been listed under separate headings below but the list is not exhaustive.

There may be other conflicts between the treeview mode and some of tksheets non-treeview functions.
Treeview usable bindings

The only bindings (using enable_bindings()) which will not cause issues are:

    "single_select"
    "drag_select"
        "select_all"
    "column_select"
    "row_select"
    "column_width_resize"
    "double_click_column_resize"
    "row_width_resize"
    "column_height_resize"
    "arrowkeys" # all arrowkeys including page up and down
    "up"
    "down"
    "left"
    "right"
    "prior" # page up
    "next" # page down
    "row_height_resize"
    "double_click_row_resize"
    "right_click_popup_menu"
    "rc_select"
    "rc_insert_column"
    "rc_delete_column"
    "ctrl_click_select" / "ctrl_select"
    "copy"
    "cut"
    "paste"
    "delete"
    "edit_cell"
    "edit_header"
    "edit_index"

Note on undo:

Take care if using "undo" because, for example, if a cell edit happens then an .insert() occurs then it will potentially make the saved cell coordinates in the undo stack relate to the wrong cells. This is because the treeview functions do not add to the undo stack.
Treeview function limitations

Many functions designed for normal tksheet usage will cause issues when used with treeview mode.

The following relates to non-treeview mode functions:

Okay:

    Modifying headers or columns.
    Modifying table or header cell contents.
    Modifying any highlights, table data formatting, table/header dropdown boxes/checkboxes, etc.

Not okay:

    Modifying the row index, unless it's through user input.
    Modifying rows, e.g. inserting, moving or deleting rows using non-treeview functions.
    Enabling and using undo, probably.

Treeview other limitations

Text alignment

The index text alignment must be "w" aka west or left.
Creating a treeview mode sheet

You can make a treeview mode sheet by using the initialization parameter treeview:

sheet = Sheet(parent, treeview=True)

See the other sections on sheet initialization and examples for the other usual Sheet() parameters.
Treeview mode functions

Functions designed for use with treeview mode.
Insert an item

insert(
    parent: str = "",
    index: None | int | Literal["end"] = None,
    iid: None | str = None,
    text: None | str = None,
    values: None | list[object] = None,
    create_selections: bool = False,
) -> str

Parameters:

    parent is the iid of the parent item (if any). If left as "" then the item will not have a parent.
    index is the row number for the item to be placed at, leave as None for the end.
    iid is a new and unique item id. It will be generated automatically if left as None.
    text is the displayed text in the row index for the item.
    values is a list of values which will become the items row in the sheet.
    create_selections when True selects the row that has just been created.

Notes:

    Returns the iid.

Example:

sheet.insert(
    iid="top level",
    text="Top level",
    values=["cell A1", "cell B1"],
)
sheet.insert(
    parent="top level",
    iid="mid level",
    text="Mid level",
    values=["cell A2", "cell B2"],
)

Insert multiple items

bulk_insert(
    data: list[list[object]],
    parent: str = "",
    index: None | int | Literal["end"] = None,
    iid_column: int | None = None,
    text_column: int | None | str = None,
    create_selections: bool = False,
    include_iid_column: bool = True,
    include_text_column: bool = True,
) -> dict[str, int]

Parameters:

    parent is the iid of the parent item (if any). If left as "" then the items will not have a parent.
    index is the row number for the items to be placed at, leave as None for the end.
    iid_column if left as None iids will be automatically generated for the new items, else you can specify a column in the data which contains the iids.
    text_column:
        If left as None there will be no displayed text next to the items.
        A text column can be provided in the data and text_column set to an int representing its index to provide the displayed text for the items.
        Or if a str is used all items will have that str as their displayed text.
    create_selections when True selects the row that has just been created.
    include_iid_column when False excludes the iid column from the inserted rows.
    include_text_column when the text_column is an int setting this to False excludes that column from the treeview.

Notes:

    Returns a dict[str, int] of key: new iids, value: their data row number.

Example:

sheet.insert(
    iid="top level",
    text="Top level",
    values=["cell A1", "cell B1"],
)
sheet.insert(
    parent="top level",
    iid="mid level",
    text="Mid level",
    values=["cell A2", "cell B2"],
)

Build a tree from data

This takes a list of lists where sublists are rows and a few arguments to bulk insert items into the treeview. Note that:

    It resets the sheet so cannot be used to bulk add to an already existing treeview.

tree_build(
    data: list[list[object]],
    iid_column: int,
    parent_column: int,
    text_column: None | int = None,
    push_ops: bool = False,
    row_heights: Sequence[int] | None | False = None,
    open_ids: Iterator[str] | None = None,
    safety: bool = True,
    ncols: int | None = None,
    lower: bool = False,
    include_iid_column: bool = True,
    include_parent_column: bool = True,
    include_text_column: bool = True,
) -> Sheet

Parameters:

    data a list of lists, one column must be an iid column, another must be a parent iid column.
    text_column if an int is used then the values in that column will populate the row index.
    push_ops when True the newly inserted rows will push all existing sheet options such as highlights downwards.
    row_heights a list of ints can be used to provide the displayed row heights in pixels (does not include hidden items). Only use if you know what you're doing here.
    open_ids a list of iids which will be opened.
    safety when True checks for infinite loops, empty iid cells and duplicate iids. No error or warning will be generated.
        In the case of infinite loops the parent iid cell will be cleared.
        In the case of empty iid cells the row will be ignored.
        In the case of duplicate iids they will be renamed and "DUPLICATED_<number>" will be attached to the end.
    ncols is like maximum columns, an int which limits the number of columns that are included in the loaded data.
    lower makes all item ids - iids lower case.
    include_iid_column when False excludes the iid column from the inserted rows.
    include_parent_column when False excludes the parent column from the inserted rows.
    include_text_column when the text_column is an int setting this to False excludes that column from the treeview.

Notes:

    Returns the Sheet object.

Example:

data = [
    ["id1", "", "id1 val"],
    ["id2", "id1", "id2 val"],
]
sheet.tree_build(
    data=data,
    iid_column=0,
    parent_column=1,
    include_iid_column=False,
    include_parent_column=False,
)

Reset the treeview

tree_reset() -> Sheet

Get treeview iids that are open

tree_get_open() -> set[str]

Set the open treeview iids

tree_set_open(open_ids: Iterator[str]) -> Sheet

    Any other iids are closed as a result.

Open treeview iids

tree_open(*items, redraw: bool = True) -> Sheet

    Opens all given iids.

Close treeview iids

tree_close(*items, redraw: bool = True) -> Sheet

    Closes all given iids.

Set or get an iids attributes

item(
    item: str,
    iid: str | None = None,
    text: str | None = None,
    values: list | None = None,
    open_: bool | None = None,
    redraw: bool = True,
) -> DotDict | Sheet

Parameters:

    item iid, required argument.
    iid use a str to rename the iid.
    text use a str to get the iid new display text in the row index.
    values use a list of values to give the item a new row of values (does not include row index).
    open_ use a bool to set the item as open or closed. False is closed.

Notes:

    If no arguments are given a DotDict is returned with the item attributes.

{
    "text": ...,
    "values": ...,
    "open_": ...,
}

Get an iids row number

itemrow(item: str) -> int

    Includes hidden rows in counting row numbers.

Get a row numbers item

rowitem(row: int, data_index: bool = False) -> str | None

    Includes hidden rows in counting row numbers. See here for more information.

Get treeview children

get_children(item: None | str = None) -> Generator[str]

    item:
        When left as None will return all iids currently in treeview, including hidden rows.
        Use an empty str ("") to get all top level iids in the treeview.
        Use an iid to get the children for that particular iid. Does not include all descendants.

get_nodes(item: None | str = None) -> Generator[str]:

    Exactly the same as above but instead of retrieving iids in the order that they appear in the treeview it retrieves iids from the internal dict which may not be ordered.

Get item descendants

descendants(item: str, check_open: bool = False) -> Generator[str]:

    Returns a generator which yields item ids in the order that they appear in the treeview.

Get the currently selected treeview item

@property
tree_selected() -> str | None:

    Returns the item id of the currently selected box row. If nothing is selected returns None.

Delete treeview items

del_items(*items) -> Sheet

    *items the iids of items to delete.
    Also deletes all item descendants.

Move items to a new parent

set_children(parent: str, *newchildren) -> Sheet

    parent the new parent for the items.
    *newchildren the items to move.

Move an item to a new parent

move(item: str, parent: str, index: int | None = None) -> Sheet

    item is the iid to move.
    parent is the new parent for the item.
        Use an empty str ("") to move the item to the top.
    index:
        Leave as None to move to item to the end of the top/children.
        Use an int to move the item to an index within its parents children (or within top level items if moving to the top).
    reattach() is exactly the same as move().

Check an item exists

exists(item: str) -> bool

    item - a treeview iid.

Get an items parent

parent(item: str) -> str

    item - a treeview iid.

Get an items index

index(item: str) -> int

    item - a treeview iid.

Check if an item is currently displayed

item_displayed(item: str) -> bool

    item - a treeview iid.

Display an item

Make sure an items parents are all open, does not scroll to the item.

display_item(item: str, redraw: bool = False) -> Sheet

    item - a treeview iid.

Scroll to an item

    Make sure an items parents are all open and scrolls to the item.

scroll_to_item(item: str, redraw: bool = False) -> Sheet

    item - a treeview iid.

Get currently selected items

selection(cells: bool = False) -> list[str]

Notes:

    Returns a list of selected iids (selected rows but as iids).

Parameters:

    cells when True any selected cells will also qualify as selected items.

Set selected items

selection_set(*items, run_binding: bool = True, redraw: bool = True) -> Sheet

    Sets selected rows (items).

Add selected items

selection_add(*items, run_binding: bool = True, redraw: bool = True) -> Sheet

Remove selections

selection_remove(*items, redraw: bool = True) -> Sheet

Toggle selections

selection_toggle(*items, redraw: bool = True) -> Sheet

Progress Bars

Progress bars can be created for individual cells. They will only update when tkinter updates.
Create a progress bar

create_progress_bar(
    row: int,
    column: int,
    bg: str,
    fg: str,
    name: Hashable,
    percent: int = 0,
    del_when_done: bool = False,
) -> Sheet

    row the row coordinate to create the bar at.
    column the column coordinate to create the bar at.
    bg the background color for the bar.
    fg the text color for the bar.
    name a name is required for easy referral to the bar later on.
        Names can be re-used for multiple bars.
    percent the starting progress of the bar as an int either 0, 100 or a number in between.
    del_when_done if True the Sheet will automatically delete the progress bar once it is modified with a percent of 100 or more.

Modify progress bars

progress_bar(
    name: Hashable | None = None,
    cell: tuple[int, int] | None = None,
    percent: int | None = None,
    bg: str | None = None,
    fg: str | None = None,
) -> Sheet

Either name or cell can be used to refer to existing progress bars:

    name the name given to a progress bar, or multiple progress bars.
        If this parameter is used then cell will not be used.
        Will modify all progress bars with the given name.
    cell (tuple[int, int]) a tuple of two ints representing the progress bars location, (row, column).
        Can only refer to one progress bar.

Values that can be modified:

    bg the background color for the bar, leave as None for no change.
    fg the text color for the bar, leave as None for no change.
    percent the progress of the bar as an int either 0, 100 or a number in between, leave as None for no change.

Delete progress bars

Note that this will delete the progress bars data from the Sheet as well.

del_progress_bar(
    name: Hashable | None = None,
    cell: tuple[int, int] | None = None,
) -> Sheet

Either name or cell can be used to refer to existing progress bars:

    name the name given to a progress bar, or multiple progress bars.
        Will delete all progress bars with the given name.
        If this parameter is used then cell will not be used.
    cell (tuple[int, int]) a tuple of two ints representing the progress bars location, (row, column).
        Can only refer to one progress bar.

Tags

Tags can be used to keep track of specific cells, rows and columns wherever they move. Note that:

    If rows/columns are deleted the the associated tags will be also.
    There is no equivalent tag_bind functionality at this time.
    All tagging functions use data indexes (not displayed indexes) - this is only relevant when there are hidden rows/columns.

Tag a specific cell

tag_cell(
    cell: tuple[int, int],
    *tags,
) -> Sheet

Example:

sheet.tag_cell((0, 0), "tag a1", "tag a1 no.2")

Tag specific rows

tag_rows(
    rows: int | Iterator[int],
    *tags,
) -> Sheet

Tag specific columns

tag_columns(
    columns: int | Iterator[int],
    *tags,
) -> Sheet

Tag using a span

tag(
    *key: CreateSpanTypes,
    tags: Iterator[str] | str = "",
) -> Sheet

Untag

untag(
    cell: tuple[int, int] | None = None,
    rows: int | Iterator[int] | None = None,
    columns: int | Iterator[int] | None = None,
) -> Sheet

    This removes all tags from the cell, rows or columns provided.

Delete tags

tag_del(
    *tags,
    cells: bool = True,
    rows: bool = True,
    columns: bool = True,
) -> Sheet

    This deletes the provided tags from all cells if True, rows if True and columns if True.

Get cells, rows or columns associated with tags

tag_has(
    *tags,
) -> DotDict

Notes:

    Returns all cells, rows and columns associated with any of the provided tags in the form of a dict with dot notation accessbility which has the following keys:
        "cells" - with a value of set[tuple[int, int]] where the tuples are cell coordinates - (row, column).
        "rows" - with a value of set[int] where the ints are rows.
        "columns" - with a value of set[int] where the ints are columns.
    Returns data indexes.
    This function updates the sets with any cells/rows/columns associated with each tag, it does not return cells/rows/columns that have all the provided tags.

Example:

sheet.tag_rows((0, 1), "row tag a", "row tag b")
sheet.tag_rows(4, "row tag b")
sheet.tag_rows(5, "row tag c")
sheet.tag_rows(6, "row tag d")
with_tags = sheet.tag_has("row tag b", "row tag c")

print (with_tags.rows)
# prints {0, 1, 4, 5}

Example Loading Data from Excel

Using pandas library, requires additional libraries:

    pandas
    openpyxl

from tksheet import Sheet
import tkinter as tk
import pandas as pd


class demo(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.grid_columnconfigure(0, weight = 1)
        self.grid_rowconfigure(0, weight = 1)
        self.frame = tk.Frame(self)
        self.frame.grid_columnconfigure(0, weight = 1)
        self.frame.grid_rowconfigure(0, weight = 1)
        self.sheet = Sheet(self.frame,
                           data = pd.read_excel("excel_file.xlsx",      # filepath here
                                                #sheet_name = "sheet1", # optional sheet name here
                                                engine = "openpyxl",

        self.sheet.enable_bindings()
        self.frame.grid(row = 0, column = 0, sticky = "nswe")
        self.sheet.grid(row = 0, column = 0, sticky = "nswe")

Example Custom Right Click and Text Editor Validation

This is to demonstrate:

    Adding your own commands to the in-built right click popup menu (or how you might start making your own right click menu functionality)
    Validating text editor input; in this demonstration the validation removes spaces from user input.

from tksheet import Sheet
import tkinter as tk


class demo(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.grid_columnconfigure(0, weight=1)
        self.grid_rowconfigure(0, weight=1)
        self.frame = tk.Frame(self)
        self.frame.grid_columnconfigure(0, weight=1)
        self.frame.grid_rowconfigure(0, weight=1)
        self.sheet = Sheet(self.frame,
                           data=[[f"Row {r}, Column {c}\nnewline1\nnewline2" for c in range(50)] for r in range(500)])
        self.sheet.enable_bindings(
            "single_select",
            "drag_select",
            "edit_cell",
            "paste",
            "cut",
            "copy",
            "delete",
            "select_all",
            "column_select",
            "row_select",
            "column_width_resize",
            "double_click_column_resize",
            "arrowkeys",
            "row_height_resize",
            "double_click_row_resize",
            "right_click_popup_menu",
            "rc_select",
        )
        self.sheet.extra_bindings("begin_edit_cell", self.begin_edit_cell)
        self.sheet.edit_validation(self.validate_edits)
        self.sheet.popup_menu_add_command("Say Hello", self.new_right_click_button)
        self.frame.grid(row=0, column=0, sticky="nswe")
        self.sheet.grid(row=0, column=0, sticky="nswe")

    def new_right_click_button(self, event=None):
        print ("Hello World!")

    def begin_edit_cell(self, event=None):
        return event.value

    def validate_edits(self, event):
        # remove spaces from any cell edits, including paste
        if isinstance(event.value, str) and event.value:
            return event.value.replace(" ", "")


app = demo()
app.mainloop()

    If you want a totally new right click menu you can use self.sheet.bind("<3>", <function>) with a tk.Menu of your own design (right click is <2> on MacOS) and don't use "right_click_popup_menu" with enable_bindings().
