npm package: @runn/react-table-6
Description: A fast, lightweight, opinionated table and datagrid built on React
Latest version: 6.11.5-custom2

# React Table v6

`react-table` is a **lightweight, fast and extendable datagrid** built for React

## Important! This is not the most recent version of React Table and is no longer receiving long-term support.

This is a v6 of react-table, due to the incredibly massive differences from v7 this branch exists as a way to access its docs and source. I do not intend on offering any long-term support for it. If you intend to keep using v6, I recommend maintaining your own fork of the library and keeping it up to date for your version of React. Otherwise, look into using [the most recent version](https://github.com/tannerlinsley/react-table) of react-table!

## Features

- Lightweight at 11kb (and just 2kb more for styles)
- Fully customizable (JSX, templates, state, styles, callbacks)
- Client-side & Server-side pagination
- Multi-sort
- Filters
- Pivoting & Aggregation
- Minimal design & easily themeable
- Fully controllable via optional props and callbacks

## Installation

Note that this installation guide uses the `react-table-v6` version of the package; while you could access the earier versions of the package by `react-table` name, in order to provide a better migration workflow from v6 to the most recent version of the 6.x.x exists as `react-table-v6`.

1.  Install React Table as a dependency

```bash
# Yarn
$ yarn add react-table-v6

# NPM
$ npm install react-table-v6
```

## Usage

2.  Import the `react-table-v6` module

```javascript
// ES6
import ReactTable from 'react-table-v6'
// ES5
var ReactTable = require('react-table-v6').default
```

3.  Import styles by including `react-table.css`

```javascript
// JS (Webpack)
import 'react-table-v6/react-table.css'
// Old-school
<link rel="stylesheet" href="node_modules/react-table-v6/react-table.css">
```

See the example below for further usage.

##### CDN

```html
<!-- CSS -->
<link
  rel="stylesheet"
  href="https://unpkg.com/react-table-v6@latest/react-table.css"
/>

<!-- JS -->
<script src="https://unpkg.com/react-table-v6@latest/react-table.js"></script>
<script src="https://unpkg.com/react-table-v6@latest/react-table.min.js"></script>

<script>
  var ReactTable = window.ReactTable.default
</script>
```

## Example

```javascript
import ReactTable from 'react-table-v6'
import 'react-table-v6/react-table.css'

render() {
  const data = [{
    name: 'Tanner Linsley',
    age: 26,
    friend: {
      name: 'Jason Maurer',
      age: 23,
    }
  },{
    ...
  }]

  const columns = [{
    Header: 'Name',
    accessor: 'name' // String-based value accessors!
  }, {
    Header: 'Age',
    accessor: 'age',
    Cell: props => <span className='number'>{props.value}</span> // Custom cell components!
  }, {
    id: 'friendName', // Required because our accessor is not a string
    Header: 'Friend Name',
    accessor: d => d.friend.name // Custom value accessors!
  }, {
    Header: props => <span>Friend Age</span>, // Custom header components!
    accessor: 'friend.age'
  }]

  return <ReactTable
    data={data}
    columns={columns}
  />
}
```

## Data

Simply pass the `data` prop anything that resembles an array or object. Client-side sorting and pagination are built in, and your table will update gracefully as you change any props. [Server-side data](#server-side-data) is also supported!

```javascript
<ReactTable
  data={[...]}
/>
```

**Pro Tip: Using the `resolveData` prop** - Any time the `data` prop value changes (using a `===` comparison), the table will update, but sometimes you need to materialize, alter, or shape this data before it enters the table. To do this, you can use the `resolveData` prop! It receives the `data` prop as the only parameter and returns the resolved data.

```javascript
<ReactTable
  data={myData} // The data prop should be immutable and only change when you want to update the table
  resolveData={data => data.map(row => row)} // But you can break immutability here because `resolveData` runs when the `data` prop changes!
/>
```

## Props

These are all of the available props (and their default values) for the main `<ReactTable />` component.

```javascript
{
  // General
  data: [],
  resolveData: data => resolvedData,
  loading: false,
  showPagination: true,
  showPaginationTop: false,
  showPaginationBottom: true
  showPageSizeOptions: true,
  pageSizeOptions: [5, 10, 20, 25, 50, 100],
  defaultPageSize: 20,
  minRows: undefined, // controls the minimum number of rows to display - default will be `pageSize`
  // NOTE: if you set minRows to 0 then you get rid of empty padding rows BUT your table formatting will also look strange when there are ZERO rows in the table
  showPageJump: true,

  },
  defaultSortMethod: (a, b, desc) => {
    // force null and undefined to the bottom
    a = a === null || a === undefined ? '' : a
    b = b === null || b === undefined ? '' : b
    // force any string values to lowercase
    a = typeof a === 'string' ? a.toLowerCase() : a
    b = typeof b === 'string' ? b.toLowerCase() : b
    // Return either 1 or -1 to indicate a sort priority
    if (a > b) {
      return 1
    }
    if (a < b) {
      return -1
    }
    // returning 0, undefined or any falsey value will use subsequent sorts or
    // the index as a tiebreaker
    return 0
  },
  PadRowComponent: () => <span>&nbsp;</span>, // the content rendered inside of a padding row

  // Controlled State Overrides (see Fully Controlled Component section)

  },

  // Global Expander Column Defaults
  // To override only some values, import { ReactTableDefaults } from 'react-table-v6

  expanderDefaults: {
    sortable: false,

  },

  // Global Pivot Column Defaults
  pivotDefaults: {},

  // Text
  previousText: 'Previous',
  nextText: 'Next',
  loadingText: 'Loading...',
  noDataText: 'No rows found',
  pageText: 'Page',
  ofText: 'of',
  rowsText: 'rows',

  // Accessibility Labels
  pageJumpText: 'jump to page',
  rowsSelectorText: 'rows per page',
}
```

You can easily override the core defaults like so:

```javascript
import { ReactTableDefaults } from 'react-table-v6'

Object.assign(ReactTableDefaults, {
  defaultPageSize: 10,
  minRows: 3
  // etc...
})
```

Or just define them as props

```javascript
<ReactTable
  defaultPageSize={10}
  minRows={3}
  // etc...
/>
```

## Columns

`<ReactTable />` requires a `columns` prop, which is an array of objects containing the following properties

```javascript
[{
  // Renderers - For more information, see "Renderers" section below
  Cell: JSX | String | Function // Used to render a standard cell, defaults to the accessed value
  Header: JSX | String | Function // Used to render the header of a column or column group
  Footer: JSX | String | Function // Used to render the footer of a column
  Filter: JSX | cellInfo => ( // Used to render the filter UI of a filter-enabled column
    <select onChange={event => onFiltersChange(event.target.value)} value={filter ? filter.value : ''}></select>
    // The value passed to onFiltersChange will be the value passed to filter.value of the filterMethod
  )
  Aggregated: JSX | String | Function // Used to render aggregated cells. Defaults to a comma separated list of values.
  Pivot: JSX | String | Function | cellInfo => ( // Used to render a pivoted cell
    <span>
      <Expander /><PivotValue /> // By default, will utilize the the PivotValue and Expander components at run time
    </span>
  ),
  PivotValue: JSX | String | Function // Used to render the value inside of a Pivot cell
  Expander: JSX | String | Function // Used to render the expander in both Pivot and Expander cells

  // General
  accessor: 'propertyName', // or Accessor eg. (row) => row.propertyName (see "Accessors" section for more details)
  id: 'myProperty', // Conditional - A unique ID is required if the accessor is not a string or if you would like to override the column name used in server-side calls
  sortable: boolean, // Overrides the table option
  resizable: boolean, // Overrides the table option
  filterable: boolean, // Overrides the table option
  show: true, // can be used to hide a column
  width: undefined, // A hardcoded width for the column. This overrides both min and max width options
  minWidth: 100, // A minimum width for this column. If there is extra room, column will flex to fill available space (up to the max-width, if set)
  maxWidth: undefined, // A maximum width for this column.

  // Special
  pivot: false,
  // Turns this column into a special column for specifying pivot position in your column definitions.
  // The `pivotDefaults` options will be applied on top of this column's options.
  // It will also let you specify rendering of the header (and header group if this special column is placed in the `columns` option of another column)
  expander: false,
  // Turns this column into a special column for specifying expander position and options in your column definitions.
  // The `expanderDefaults` options will be applied on top of this column's options.
  // It will also let you specify rendering of the header (and header group if this special column is placed in the `columns` option of another column) and
  // the rendering of the expander itself via the `Expander` property

  // Cell Options
  className: '', // Set the classname of the `td` element of the column
  style: {}, // Set the style of the `td` element of the column
  // Header & HeaderGroup Options
  headerClassName: '', // Set the classname of the `th` element of the column
  headerStyle: {}, // Set the style of the `th` element of the column
  getHeaderProps: (state, rowInfo, column, instance) => ({}), // a function that returns props to decorate the `th` element of the column

  // Header Groups only
  columns: [...], // See Header Groups section below

  // Footer
  footerClassName: '', // Set the classname of the `td` element of the column's footer
  footerStyle: {}, // Set the style of the `td` element of the column's footer
  getFooterProps: (state, rowInfo, column, instance) => ({}), // A function that returns props to decorate the `td` element of the column's footer

  // Filtering
  filterMethod: (filter, row || rows, column) => {return true}, // A function returning a boolean that specifies the filtering logic for the column
    // 'filter' == an object specifying which filter is being applied. Format: {id: [the filter column's id], value: [the value the user typed in the filter field], pivotId: [if filtering on a pivot column, the pivotId will be set to the pivot column's id and the `id` field will be set to the top level pivoting column]}
    // 'row' || 'rows' == the row (or rows, if filterAll is set to true) of data supplied to the table
    // 'column' == the column that the filter is on
  filterAll: false
}]
```

## Renderers

React Table supports very flexible renderers for just about everything:

- `Cell` - Renders a standard cell
- `Header` - Renders a column header or column group header
- `Footer` - Renders a column footer
- `Filter` - Renders a column's filter UI
- `Aggregated` - Renders an aggregated cell
- `Pivot` - Renders a pivoted cell (by default, will utilize `Expander` and `PivotValue` renderers)
- `PivotValue` - Renders the value inside a `Pivot` renderer
- `Expander` - Renders the Expander used in both the default `Pivot` renderer and any expander-designated column

Any of these renderers can be one of the following:

- A React Class
- JSX or any rendered react component
- Stateless functional component
- Function that returns any primitive

All of these formats receive the following props:

```javascript
{
  // Row-level props
  row: Object, // the materialized row of data
  original: , // the original row of data
  index: '', // the index of the row in the original array
  viewIndex: '', // the index of the row relative to the current view
  level: '', // the nesting level of this row
  nestingPath: '', // the nesting path of this row
  aggregated: '', // true if this row's values were aggregated
  groupedByPivot: '', // true if this row was produced by a pivot
  subRows: '', // any sub rows defined by the `subRowKey` prop

  // Cells-level props
  isExpanded: '', // true if this row is expanded
  value: '', // the materialized value of this cell
  resized: '', // the resize information for this cell's column
  show: '', // true if the column is visible
  width: '', // the resolved width of this cell
  maxWidth: '', // the resolved maxWidth of this cell
  tdProps: '', // the resolved tdProps from `getTdProps` for this cell
  columnProps: '', // the resolved column props from 'getProps' for this cell's column
  classes: '', // the resolved array of classes for this cell
  styles: '' // the resolved styles for this cell
}
```

## Accessors

Accessors are functions that return the value to populate the row's value for the column.
This lets the render function not have to worry about accessing the correct data, the value is automatically populated in it's props.

If a `string` or `array` is passed the default accessor is used.
The default accessor will parse the input into an array and recursively flatten it.
Any values that contain a dot (`.`) will be split.
Any values that contain bracket (`[]`) will be split.
This array is then used as the path to the value to return.

("\$" is the placeholder value that would be returned by the default accessor)

| value        | path            | data                    |
| ------------ | --------------- | ----------------------- |
| "a"          | ["a"]           | {"a": \$}               |
| "a.b"        | ["a", "b"]      | {"a": {"b": \$}}        |
| "a[0]"       | ["a", "0"]      | {"a": [$]}              |
| ["a.b", "c"] | ["a", "b", "c"] | {"a": {"b": {"c": \$}}} |

_NOTE_
If your data has a field/key with a dot (`.`) you will need to supply a custom accessor.

## Column Header Groups

To group columns with another header column, just nest your columns in a header column. Header columns utilize the same header properties as regular columns.

```javascript
const columns = [{
  Header: 'Favorites',
  headerClassName: 'my-favorites-column-header-group'
  columns: [{
    Header: 'Color',
    accessor: 'favorites.color'
  }, {
    Header: 'Food',
    accessor: 'favorites.food'
  }, {
    Header: 'Actor',
    accessor: 'favorites.actor'
  }]
}]
```

## Custom Cell, Header and Footer Rendering

You can use any react component or JSX to display content in column headers, cells and footers. Any component you use will be passed the following props (if available):

- `row` - Original row from your data
- `original` - The post-accessed values from the original row
- `index` - The index of the row
- `viewIndex` - the index of the row relative to the current page
- `level` - The nesting depth (zero-indexed)
- `nestingPath` - The nesting path of the row
- `aggregated` - A boolean stating if the row is an aggregation row
- `subRows` - An array of any expandable sub-rows contained in this row

```javascript
// This column uses a stateless component to produce a different colored bar depending on the value
// You can also use stateful components or any other function that returns JSX
const columns = [
  {
    Header: () => (
      <span>
        <i className="fa-tasks" /> Progress
      </span>
    ),
    accessor: 'progress',
    Cell: row => (
      <div
        style={{
          width: '100%',
          height: '100%',
          backgroundColor: '#dadada',
          borderRadius: '2px'
        }}
      >
        <div
          style={{
            width: `${row.value}%`,
            height: '100%',
            backgroundColor:
              row.value > 66
                ? '#85cc00'
                : row.value > 33
                ? '#ffbf00'
                : '#ff2e00',
            borderRadius: '2px',
            transition: 'all .2s ease-out'
          }}
        />
      </div>
    )
  }
]
```

## Styles

- React-table ships with a minimal and clean stylesheet to get you on your feet quickly.
- The stylesheet is located at `react-table-v6/react-table.css`.
- There are countless ways to import a stylesheet. If you have questions on how to do so, consult the documentation of your build system.

#### Classes

- Adding a `-striped` className to ReactTable will slightly color odd numbered rows for legibility
- Adding a `-highlight` className to ReactTable will highlight any row as you hover over it

#### CSS

We think the default styles looks great! But, if you prefer a more custom look, all of the included styles are easily overridable. Every single component contains a unique class that makes it super easy to customize. Just go for it!

#### JS Styles

Every single react-table element and `get[ComponentName]Props` callback supports `classname` and `style` props.

## Custom Props

#### Built-in Components

Every single built-in component's props can be dynamically extended using any one of these prop-callbacks:

```javascript
<ReactTable
  getProps={fn}
  getTableProps={fn}
  getTheadGroupProps={fn}
  getTheadGroupTrProps={fn}
  getTheadGroupThProps={fn}
  getTheadProps={fn}
  getTheadTrProps={fn}
  getTheadThProps={fn}
  getTheadFilterProps={fn}
  getTheadFilterTrProps={fn}
  getTheadFilterThProps={fn}
  getTbodyProps={fn}
  getTrGroupProps={fn}
  getTrProps={fn}
  getTdProps={fn}
  getPaginationProps={fn}
  getLoadingProps={fn}
  getNoDataProps={fn}
  getResizerProps={fn}
/>
```

If used, **a callback prop must return a valid object**, even if it's an empty one.

These callbacks are executed with each render of the element with four parameters:

1.  Table State
2.  RowInfo (undefined if not applicable)
3.  Column (undefined if not applicable)
4.  React Table Instance

This makes it extremely easy to add, say... a row click callback!

```javascript
// When any Td element is clicked, we'll log out some information
<ReactTable
  getTdProps={(state, rowInfo, column, instance) => {
    return {
      onClick: (e, handleOriginal) => {
        console.log('A Td Element was clicked!')
        console.log('it produced this event:', e)
        console.log('It was in this column:', column)
        console.log('It was in this row:', rowInfo)
        console.log('It was in this table instance:', instance)

        // IMPORTANT! React-Table uses onClick internally to trigger
        // events like expanding SubComponents and pivots.
        // By default a custom 'onClick' handler will override this functionality.
        // If you want to fire the original onClick handler, call the
        // 'handleOriginal' function.
        if (handleOriginal) {
          handleOriginal()
        }
      }
    }
  }}
/>
```

You can use these callbacks for dynamic styling as well!

```javascript
// Any Tr element will be green if its (row.age > 20)
<ReactTable
  getTrProps={(state, rowInfo, column) => {
    return {
      style: {
        background: rowInfo.row.age > 20 ? 'green' : 'red'
      }
    }
  }}
/>
```

#### Column Components

Just as core components can have dynamic props, columns and column headers can too!

You can utilize either of these prop callbacks on columns:

```javascript
const columns = [{
  getHeaderProps: () => (...),
  getProps: () => (...)
}]
```

In a similar fashion these can be used to dynamically style just about anything!

```javascript
// This columns cells will be red if (row.name === Santa Clause)
const columns = [
  {
    getProps: (state, rowInfo, column) => {
      return {
        style: {
          background: rowInfo.row.name === 'Santa Clause' ? 'red' : null
        }
      }
    }
  }
]
```

## Pivoting and Aggregation

Pivoting the table will group records together based on their accessed values and allow the rows in that group to be expanded underneath it.
To pivot, pass an array of `columnID`'s to `pivotBy`. Remember, a column's `id` is either the one that you assign it (when using a custom accessors) or its `accessor` string.

```javascript
<ReactTable
  ...
  pivotBy={['lastName', 'age']}
/>
```

Naturally when grouping rows together, you may want to aggregate the rows inside it into the grouped column. No aggregation is done by default, however, it is very simple to aggregate any pivoted columns:

```javascript
// In this example, we use lodash to sum and average the values, but you can use whatever you want to aggregate.
const columns = [
  {
    Header: 'Age',
    accessor: 'age',
    aggregate: (values, rows) => _.round(_.mean(values)),
    Aggregated: row => {
      // You can even render the cell differently if it's an aggregated cell
      return <span>row.value (avg)</span>
    }
  },
  {
    Header: 'Visits',
    accessor: 'visits',
    aggregate: (values, rows) => _.sum(values)
  }
]
```

Pivoted columns can be sorted just like regular columns including holding down the `<shift>` button to multi-sort.

## Sub Tables and Sub Components

By adding a `SubComponent` props, you can easily add an expansion level to all root-level rows:

```javascript
<ReactTable
  data={data}
  columns={columns}
  defaultPageSize={10}
  SubComponent={row => {
    return (
      <div>
        You can put any component you want here, even another React Table! You
        even have access to the row-level data if you need! Spark-charts,
        drill-throughs, infographics... the possibilities are endless!
      </div>
    )
  }}
/>
```

## Server-side Data

If you want to handle pagination, sorting, and filtering on the server, `react-table` makes it easy on you.

1.  Feed React Table `data` from somewhere dynamic. eg. `state`, a redux store, etc...
1.  Add `manual` as a prop. This informs React Table that you'll be handling sorting and pagination server-side
1.  Subscribe to the `onFetchData` prop. This function is called at `componentDidMount` and any time sorting, pagination or filterting is changed in the table
1.  In the `onFetchData` callback, request your data using the provided information in the params of the function (current state and instance)
1.  Update your data with the rows to be displayed
1.  Optionally set how many pages there are total

```javascript
<ReactTable
  ...
  data={this.state.data} // should default to []
  pages={this.state.pages} // should default to -1 (which means we don't know how many pages we have)
  loading={this.state.loading}
  manual // informs React Table that you'll be handling sorting and pagination server-side
  onFetchData={(state, instance) => {
    // show the loading overlay
    this.setState({loading: true})
    // fetch your data
    Axios.post('mysite.com/data', {
      page: state.page,
      pageSize: state.pageSize,
      sorted: state.sorted,
      filtered: state.filtered
    })
      .then((res) => {
        // Update react-table
        this.setState({
          data: res.data.rows,
          pages: res.data.pages,
          loading: false
        })
      })
  }}
/>
```

For a detailed example, take a peek at our <a href="https://react-table.js.org/#/story/server-side-data" target="\_parent">async table mockup</a>

## Fully Controlled Component

React Table by default works fantastically out of the box, but you can achieve even more control and customization if you choose to maintain the state yourself. It is very easy to do, even if you only want to manage _parts_ of the state.

Here are the props and their corresponding callbacks that control the state of the a table:

```javascript
<ReactTable
  // Props
  page={0} // the index of the page you wish to display
  pageSize={20} // the number of rows per page to be displayed
  sorted={[{ // the sorting model for the table
      id: 'lastName',
      desc: true
    }, {
      id: 'firstName',
      desc: true
  }]}
  expanded={{ // The nested row indexes on the current page that should appear expanded
    1: true,
    4: true,
    5: {
      2: true,
      3: true
    }
  }}
  filtered={[{ // the current filters model
    id: 'lastName',
    value: 'linsley'
  }]}
  resized={[{ // the current resized column model
    "id": "lastName",
    "value": 446.25
  }]}

  // Callbacks
  onPageChange={(pageIndex) => {...}} // Called when the page index is changed by the user
  onPageSizeChange={(pageSize, pageIndex) => {...}} // Called when the pageSize is changed by the user. The resolve page is also sent to maintain approximate position in the data
  onSortedChange={(newSorted, column, shiftKey) => {...}} // Called when a sortable column header is clicked with the column itself and if the shiftkey was held. If the column is a pivoted column, `column` will be an array of columns
  onExpandedChange={(newExpanded, index, event) => {...}} // Called when an expander is clicked. Use this to manage `expanded`
  onFilteredChange={(filtered, column) => {...}} // Called when a user enters a value into a filter input field or the value passed to the onFiltersChange handler by the Filter option.
  onResizedChange={(newResized, event) => {...}} // Called when a user clicks on a resizing component (the right edge of a column header)
/>
```

## Functional Rendering

Possibly one of the coolest features of React-Table is its ability to expose internal components and state for custom render logic. The easiest way to do this is to pass a function as the child of `<ReactTable />`.

The function you pass will be called with the following items:

- Fully-resolved state of the table
- A function that returns the standard table component
- The instance of the component

You can then return any JSX or react you want! This turns out to be perfect for:

- Accessing the internal state of the table without a `ref`
- Decorating the table or extending it with your own UI
- Building your own custom display logic

Accessing internal state and wrapping with more UI:

```javascript
<ReactTable data={data} columns={columns}>
  {(state, makeTable, instance) => {
    return (
      <div
        style={{
          background: '#ffcf00',
          borderRadius: '5px',
          overflow: 'hidden',
          padding: '5px'
        }}
      >
        <pre>
          <code>
            state.allVisibleColumns ==={' '}
            {JSON.stringify(state.allVisibleColumns, null, 4)}
          </code>
        </pre>
        {makeTable()}
      </div>
    )
  }}
</ReactTable>
```

The possibilities are endless!

## Sorting

Sorting comes built in with React-Table.

- Click a column header to sort by its accessor.
- Click it again to reverse the sort.
- Set `defaultSortDesc` property to `true` to make the first sort direction default to descending.
- Override a specific column's default sort direction by using the same `defaultSortDesc` property on a column, set to `true`

## Multi-Sort

When clicking on a column header, hold shift to multi-sort! You can toggle `ascending` `descending` and `none` for multi-sort columns. Clicking on a header without holding shift will clear the multi-sort and replace it with the single sort of that column. It's quite handy!

You can set the `multiSort` prop to `false` to disable this feature (which may be useful for server-side sorting when you are not
going to sort multiple columns).

## Custom Sorting Algorithm

To override the default sorting algorithm for the whole table use the `defaultSortMethod` prop.

To override the sorting algorithm for a single column, use the `sortMethod` column property.

Supply a function that implements the native javascript [`Array.sort`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort) interface. This is React Table's default sorting algorithm:

- `a` the first value to compare
- `b` the second value to compare
- `desc` true if sort is descending, false if ascending

```javascript
defaultSortMethod = (a, b, desc) => {
  // force null and undefined to the bottom
  a = a === null || a === undefined ? -Infinity : a
  b = b === null || b === undefined ? -Infinity : b
  // force any string values to lowercase
  a = typeof a === 'string' ? a.toLowerCase() : a
  b = typeof b === 'string' ? b.toLowerCase() : b
  // Return either 1 or -1 to indicate a sort priority
  if (a > b) {
    return 1
  }
  if (a < b) {
    return -1
  }
  // returning 0 or undefined will use any subsequent column sorting methods or the row index as a tiebreaker
  return 0
}
```

## Filtering

Filtering can be enabled by setting the `filterable` option on the table.

If you don't want particular column to be filtered you can set the `filterable={false}` option on the column.

By default the table tries to filter by checking if the row's value starts with the filter text. The default method for filtering the table can be set with the table's `defaultFilterMethod` option.

If you want to override a particular column's filtering method, you can set the `filterMethod` option on a column.

By default, `filterMethod` is passed a single row of data at a time, and you are responsible for returning `true` or `false`, indicating whether it should be shown.

Alternatively, you can set `filterAll` to `true`, and `filterMethod` will be passed the entire array of rows to be filtered, and you will then be responsible for returning the new filtered array. This is extremely handy when you need to utilize a utility like fuzzy matching that requires the entire array of items.

To completely override the filter that is shown, you can set the `Filter` column option. Using this option you can specify the JSX that is shown. The option is passed an `onChange` method which must be called with the the value that you want to pass to the `filterMethod` option whenever the filter has changed.

See <a href="https://codesandbox.io/s/github/tannerlinsley/react-table/tree/v6/examples/custom-filtering" target="\_parent">Custom Filtering</a> demo for examples.

## Component Overrides

Though we confidently stand by the markup and architecture behind it, `react-table` does offer the ability to change the core componentry it uses to render everything. You can extend or override these internal components by passing a react component to it's corresponding prop on either the global props or on a one-off basis like so:

```javascript
// Change the global default
import { ReactTableDefaults } from 'react-table-v6'
Object.assign(ReactTableDefaults, {
  TableComponent: component,
  TheadComponent: component,
  TbodyComponent: component,
  TrGroupComponent: component,
  TrComponent: component,
  ThComponent: component,
  TdComponent: component,
  TfootComponent: component,
  ExpanderComponent: component,
  AggregatedComponent: component,
  PivotValueComponent: component,
  PivotComponent: component,
  FilterComponent: component,
  PaginationComponent: component,
  PreviousComponent: undefined,
  NextComponent: undefined,
  LoadingComponent: component,
  NoDataComponent: component,
  ResizerComponent: component
})

// Or change per instance
<ReactTable
  TableComponent={Component},
  TheadComponent={Component},
  // etc...
  />
```

If you choose to change the core components React-Table uses to render, you must make sure your replacement components consume and utilize all of the supplied and inherited props that are needed for that component to function properly. We would suggest investigating <a href="https://github.com/tannerlinsley/react-table/blob/v6/src/index.js" target="\_parent">the source</a> for the component you wish to replace.

# HOC Extensions

This section is about expanding ReactTable using Higher Order Components/Functions.

## Covered in this section

- A Brief explanation of HOCs and why they are a good approach for ReactTable enhancements
- Documentation of the currently available HOCs
- TreeTable
- SelectTable
- Documentation of the standard for writing HOCs with ReactTable

## What are HOCs and why use them with ReactTable

HOCs (or Higher Order Components/Functions) are either a React Component (or a function that returns a React Component)
that are used to enhance the functionality of an existing component. How much you can enhance depends on the props that
the component exposes.

Fortunately, ReactTable exposes a LOT of functionality as props to the component. In some cases there are too many
props to keep track of and that is where HOCs come in.

You can write a HOC that just focusses on the additional functionality you want to enhance and keep those enhancements to
reuse over and over again when you need them. You don't have to edit the ReactTable source code, just wrap ReactTable in one or
more HOCs (more on some issues related to chaining HOCs later) that provide the additional functionality you want to expose.

The most obvious HOC is one that can add `checkbox` or select functionality. The HOC included provides `select` functionality
that allows the developer to specify if they want a `checkbox` or `radio` style of select column. The implementation of the
selection is recorded (e.g. in component state, Redux, etc.) and how to manage multiple selections. The HOC really only handles
the rendering pieces.

But there is more documentation on the `select` HOC below.

## Currently Available HOCs

Any of the below HOCs can be imported from react-table like so:

```javascript
import ReactTable from "react-table-v6";
import treeTableHOC from "react-table-v6/lib/hoc/treeTable";

const TreeTable = treeTableHOC(ReactTable);
```

Swap `treeTable` and `TreeTable` with any of the other HOC names as necessary.

### TreeTable

TreeTable takes over the rendering of the generated pivot rows of ReactTable so that they appear more like an expandable Tree.

It accomplishes this by rendering a 100% wide div and then only rendering the cell that controls the pivot at that level.

Using it is as simple as doing the following:

```javascript
const TreeTable = treeTableHOC(ReactTable);
```

After you have done the above, you can then use `TreeTable` just as you would `ReactTable` but it will render pivots using
the Tree style described above.

### SelectTable

SelectTable is a little trickier. The HOCs attempt to avoid adding additional state and, as there is no internal ID for a row that
can be relied on to be static (ReactTable just reuses indexes when rendering) the developer has to maintain the state outside of even
the wrapped component. So it is largely based on callbacks.

You include the HOC in the same manner as you would for the treeTableHOC but then need to provide the following overrides:

- isSelected - returns `true` if the key passed is selected otherwise it should return `false`
- selectAll - a property that indicates if the selectAll is set (`true|false`)
- toggleAll - called when the user clicks the `selectAll` checkbox/radio
- toggleSelection - called when the use clicks a specific checkbox/radio in a row
- selectType - either `checkbox|radio` to indicate what type of selection is required

**Note:** The select field defaults to the accessor `_id` property in order to render the select field for that particular row. If your objects have different
unique ID fields, make sure to tell React Table that by passing it the `keyField` property.

```javascript
<ReactTable keyField="id" />
```

In the case of `radio` there is no `selectAll` displayed but the developer is responsible for only making one selection in
the controlling component's state. You could select multiple but it wouldn't make sense and you should use `checkbox` instead.

You also have to decide what `selectAll` means. Given ReactTable is a paged solution there are other records off-page. When someone
selects the `selectAll` checkbox, should it mark every possible record, only what might be visible to due a Filter or only those items
on the current page?

The example opts for the middle approach so it gets a `ref` to the ReactTable instance and pulls the `sortedData` out of the resolved
state (then walks through those records and pulls their ID into the `selection` state of the controlling component).

You can also replace the input component that is used to render the select box and select all box:

- SelectAllInputComponent - the checkbox in the top left corner
- SelectInputComponent - the checkbox used on a row

### SelectTreeTable

SelectTreeTable is a combination of TreeTable and SelectTable.

To function correctly the chain has to be in the correct order as follows (see the comments in the guid on HOCs below).

```javascript
const SelectTreeTable = selectTableHOC(treeTableHOC(ReactTable));
```

In this particular instance it is (probably) because the functions need access to the state on the wrapped component to manage
the selected items. Although that is not totally clearly the issue.

### FoldableTable

FoldableTable is a HOC that make the columns are foldable. The reason I developed this HOC because when working on the real project related to the financial which display so many columns for validation and comparison.

So foldable columns allow users to temporary hidden the unwanted to columns so that they can focus on the data that they want to see.

#### How it works

```javascript
const FoldableTable = FoldableTableHOC(ReactTable);
```

It will scan all the columns which `foldable` is `true` and apply the foldable column feature. This feature will work for both normal columns and header columns as samples below.

- With Header Columns

```javascript
render(){
  return <FoldableTable
           columns={[{
              Header: "Name",
              foldable: true,
              columns: [{
                  Header: "First Name",
                  accessor: "first_name"
                },{
                  Header: "Last Name",
                  accessor: "last_name"
                }]
              },{
              Header: "Info",
              foldable: true,
              columns: [{
                  Header: "Email",
                  accessor: "email"
                },{
                  Header: "Gender",
                  accessor: "gender"
               }]
            }]
        }/>
}
```

![With Header Columns](https://raw.githubusercontent.com/baoduy/Images/master/Wordpress/JavaScripts/react-table%20foldableHOC/FoldableTable%20With%20Header.gif)

- With Nornal Columns

```javascript
render() {
    return <FoldableTable
        columns={[{
                Header: "First Name",
                accessor: "first_name"
            },
            {
                Header: "Last Name",
                accessor: "last_name",
                foldable: true,
            },
            {
                Header: "Email",
                accessor: "email",
                foldable: true,
            },
            {
                Header: "Gender",
                accessor: "gender",
                foldable: true,
            }]}></FoldableTable>
}
```

![With Normal Columns](https://raw.githubusercontent.com/baoduy/Images/master/Wordpress/JavaScripts/react-table%20foldableHOC/FoldableTable%20Without%20Header.gif)

- The `FoldableTable` also fully compatible with existing HOCs, below is with selectTableHOC.

![With Normal Columns](https://raw.githubusercontent.com/baoduy/Images/master/Wordpress/JavaScripts/react-table%20foldableHOC/FoldableTable%20With%20selectTable.gif)

#### State management

If you would like to manage the state of FoldableTable, then add the following codes.

```javascript
render() {
    return <FoldableTable
        onFoldChange={newFolded => this.setState(p => { return { folded: newFolded } })}
       folded={this.state.folded}
       />
}
```

#### Custom Components

- FoldIconComponent: to render the Icon of buttons.
- FoldButtonComponent: to render the folding buttons for each Column.
  With default rendering as below.

```javascript
const defaultFoldIconComponent = ({ collapsed }) => {
  //Render your Icon here
};

const defaultFoldButtonComponent = ({ header, collapsed, icon, onClick }) => {
  //Render your button here.
};
```

### AdvancedExpandTable

HOC which allows any Cell in the row to toggle the row's
SubComponent (expand/collapse). Also allows the SubComponent to toggle itself. Technically supports toggling any row's SubComponent.

These are the expand functions available to any SubComponent or Column Cell:

```
toggleRowSubComponent
showRowSubComponent
hideRowSubComponent
```

They are available through the `props.columnProps.rest` object.

On any change to the props, the table will reset the expanded state.

Accepts a onExpandedChange callback to be called whenever the table expanded state changes

Note: only supports 1 level of nesting.

Example usage in a Column Cell Renderer:

```javascript
    Cell: props => {
      const {
        value
        columnProps: { rest: { showRowSubComponent } },
        nestingPath
      } = props;
      return (
        <div>
          <button
            onClick={e => showRowSubComponent(nestingPath, e)}
          >
            {value}
          </button>
        </div>
      );
    }
```

Example usage in the ReactTable SubComponent (toggle itself):

```javascript
  const AdvancedExpandReactTable = advancedExpandTableHOC(ReactTable);

  <AdvancedExpandReactTable>
  ...
  SubComponent={({ row, nestingPath, toggleRowSubComponent }) => {
    return (
      <div>
        <button
          onClick={e => toggleRowSubComponent({ nestingPath }, e)}
        >
          {row.value}
        </button>
      </div>
    );
  }}
  />
```

Each Column Renderer (E.g. Cell ) gets the expand functions in its props and each SubComponent gets the expand functions in its props

Expand functions takes the `nestingPath` or `rowInfo` given to each
Column Renderer and SubComponent already by ReactTable.

## HOC Guide for ReactTable

There are a few rules required when writing a HOC for ReactTable (other than meeting the normal lint standards - which are
still being developed).

Firstly, there are issues with `ref` when you write a HOC. Consider a deeply nested component wrapped in multiple HOCs...

A HOC in the middle of the chain requires access to the instance of the component it thinks it is wrapping but there is at
least one other wrapper in the way. The challenge is: How do I get to the actual wrapped component?

Each HOC is required to be a React Class so that a `ref` can be obtained against each component:

```Javascript
<Component ... ref={r => this.wrappedInstance = r} />
```

_NOTE:_ "Component" can also be the `<ReactTable />` instance.

Then the following method needs
to be placed on the class so that it exposes the correct instance of ReactTable:

```Javascript
getWrappedInstance() {
  if (!this.wrappedInstance) console.warn('<component name here> - No wrapped instance')
  if (this.wrappedInstance.getWrappedInstance) return this.wrappedInstance.getWrappedInstance()
  else return this.wrappedInstance
}
```

Essentially this will walk down the chain (if there are chained HOCs) and stop when it gets to the end and return the wrapped instance.

Finally, sometimes the chains need to be in a specific order to function correctly. It is not clear if this is just an architectural
issue or if it would be better solved using a library like `recompose`. Anyone who is able to contribute a reliable solution to this
is welcome to submit a PR.
