/**
 * 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:
 *
 * ```ts
 * 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>
 * ```
