### SCSS

The update to tables splits out the `scss` files into multiple partial files with specific functionality, with a main index file bringing them together.

### JavaScript

#### Getting component class reference

##### ES2015

```javascript
import { DataTableV2 } from 'carbon-components';
```

##### With pre-build bundle (`carbon-components.min.js`)

```javascript
var DataTableV2 = CarbonComponents.DataTableV2;
```

#### Instantiating

```javascript
// `#my-data-table-v2` is an element with `[data-data-table-v2]` attribute
DataTableV2.create(document.getElementById('my-data-table-v2'));
```

#### Public Methods

| Name        | Params | Descriptions                                                                                                      |
|-------------|--------|-------------------------------------------------------------------------------------------------------------------|
| release     |        | Deletes the instance and removes document event listeners                                                         |
| refreshRows |        | When adding in new table rows, reinitialize parent-child relationships. Not required if not using expandable rows |

##### Example - Keeping data table in sync with dynamic change in rows list (For expantable table)

```javascript
// `#my-data-table-v2` is an element with `[data-data-table-v2]` attribute
var dataTableV2Instance = DataTableV2.create(document.getElementById('my-data-table-v2'));
dataTableV2Instance.refreshRows();
```

  if (!myApplication.shouldToggleExpando(evt.target)) {
    evt.preventDefault();
  }
});
```

##### Example - Sorting table content

```javascript
document.addEventListener('data-table-v2-aftertogglesort', function (evt) {
  // `evt.target` will be `div.bx--data-table-v2-container`
  // `evt.detail.element` will be `button.bx--table-sort-v2` whose sorting is changed,
  // and will have `bx--table-sort-v2--ascending` class or not depending on the sorting state
  evt.target.querySelector('tbody').innerHTML
    = myApplication.resortTableContent(evt.target, evt.detail.element);
});
```

### FAQ

**How do I sort the tables**
The table component does not sort the table for you, rather it emits an event and toggles the sort UI. It is up to the user to re-render the table rows sorted; you can see this in action [in the React Storybook](http://react.carbondesignsystem.com/?selectedKind=DataTable&selectedStory=with%20sorting&full=0&addons=1&stories=1&panelRight=0&addonPanel=storybook%2Factions%2Factions-panel).

**How do I use the expandable rows**
If you would like to programmatically expand table rows, you can add the `bx--expandable-row-v2` to the `selectorParentRows` elements.

**How do I activate the batch actions pane**
If you would like to programmatically activate the batch actions pane, you can add `bx--batch-actions--active` to the `bx--batch-actions` element.
