# TableConversionAdditionalSlot

interface

By default, only the `tableRow` elements from the `table` model are downcast inside the `<table>` and all other elements are pushed outside the table. This handler allows creating additional slots inside the table for other elements.

Take this model as an example:

```xml
<table>
  <tableRow>...</tableRow>
  <tableRow>...</tableRow>
  <tableColumnGroup>...</tableColumnGroup>
</table>
```

By default, downcasting result will be:

```xml
<table>
  <tbody>
	<tr>...</tr>
	<tr>...</tr>
  </tbody>
</table>
<colgroup>...</colgroup>
```

To allow the `tableColumnGroup` element at the end of the table, use the following configuration:

```typescript
const additionalSlot = {
  filter: element => element.is( 'element', 'tableColumnGroup' ),
  positionOffset: 'end'
}
```

Now, the downcast result will be:

```xml
<table>
  <tbody>
	<tr>...</tr>
	<tr>...</tr>
  </tbody>
  <colgroup>...</colgroup>
</table>
```
