# API        
The component is highly configurable and customizable through many *Input*s and *Event*s.
  
## app-ftn-data-table
* `title` (`string` | default: `''`) table's name - it's highly recommend it's set for accessibility reasons as this will provide a better experience when interacting with the component, especially through a SR.
* `showTitle` (`boolean` | default: `true`): if `false`, the title is not shown into the component. Useful when want the header component visible (with its Reload and Coulumn Selector buttons), but not the title.
* `className` (`string` | default: `''`) setting class for datatable (Bootstrap Class DataTable). 
* `items` (`JsonObject[]` | default: `[]`) table data to show.
* `itemCount` (`number` | default: `0`) items's count.
* `showButtonReloadItems` (`boolean` | default: `false`) show/hide button reload datatable items.
* `showButtonChooseColumns` (`boolean` | default: `false`) show/hide button for choose columns.  
* `header` (`boolean` | default: `true`) show/hide the table header sub-component - this holds the table name and two buttons (_reload table_ and _column selector_).
* `pagination` (`boolean` | default: ) enable pagination. If `true`, pagination controls are shown at the bottom of the table.
* `indexColumn` (`boolean` | default: `true`) when `true` the table shows a 0-indexed column.
* `indexColumnHeader` (`string` | default: `''`) text shown as column header for the index column.
* `selectColumn` (`boolean` | default: `false`) when `true` the table shows a checkbox column for selecting specific row.
* `multiSelect` (`boolean` | default: `false`) allows multi-row selection, showing a checkbox at select's column header.
* `labels` (`DataTableTranslations` | default: `defaultTranslations`) interface holding all needed labels. You can pass a subset of the labels. The missing labels will be defaulted.
* `expandableRow` (`boolean` | default: `false`) when `true` each row will have a collapsible content.
* `selectOnRowClick` (`boolean` | default: `false`) when `true` each row is selectable via a single-click.
* `reload` (`function(): void` | default: `null`) function that is invoked when the table needs to re-render its data. Note: most of the times this is the place where the developer connects to a server in order to pull down the item set.
* `autoReload`  (`boolean` | default: `false`) when `true`, the `reload` function gets invoked and init time (`ngOnInit`).
* `rowColors` (`function(): 'color` | default: `null`) custom function that must return a _CSS color_ that will be applied to the entire row.
* `rowTooltip` (`function` | default: `null`) custom function to show a title tooltip when hovering the row.
* `showReloading` (`boolean` | default: `true`) when `true` an overlay with a gear icon is shown on top of the table while it's reloading.
* `noDataMessage` (`string` | default: `''`) message displayed when no item are displayed. If it's empty nothing is shown.
* `pageLimits` (`number[]` | default: `[10, 25, 50, 100, 250]`) items per page selector options.
* `primaryColumn` (`string` | default: first data column) it identifies which columns has be marked as primary. This is an important aspect from an accessibility and SR perspective. If not given, the first column will be the primary column.
* `page` (`number` | default: `0`) page to load, valid only if pagination is enabled.
* `limit` (`number` | default: `10`) number of items per page, valid only pagination is enabled. If `limit` value is not a valid (not contained into `pageLimits` array) it will be defaulted to `pageLimits`'s first value. 
* `sortBy` (`string` | default: `''`) column table is sorted by.
* `sortAsc` (`boolean` | default: `true`) valid only if `sortBy` is not defaulted. Defines the sorting order. If `true` sort is ascending, descending otherwise.

## data-table-column
* `property` (`string` | default: _no default_) item's `JSONObject` key used to retrieve the row cell content.
* `header` (`string` | default: _no default_) column header text.
* `sortable` (`boolean` | default: `false`) marks the columns as sortable.
* `resizable` (`boolean` | default: `false`) marks the columns as resizable.
* `visible` (`boolean` | default: `true`) marks the columns visible.
* `width` (`number | string` | default: `''`) defines the column width. It can be a string like `2rem` or a number. If it's a number, it will be considered as pixels.

### Custom column templates
data-column's content and header are not restricted to be text only. They can hold more complex components. In order to do that developers can use two references: `#dataTableHeader` and `#dataTableCell`.

#### Usage and sample
```html
<app-ftn-data-table>
  ...
  <data-table-column
    header="Actions">
    <ng-template #dataTableHeader let-item="item">
      <i>Actions</i>
    </ng-template>
    <ng-template #dataTableCell let-item="item">
      <button (click)="carClicked(item)" class="btn btn-sm btn-default">Buy</button>
    </ng-template>
  </data-table-column>
  ...
</app-ftn-data-table>
```
