## Description

The RTE misses table configuration for floating toolbar

### Expected behavior

I would like to remove columns, remove rows and do things with the floating table toolbar

Add:

```yaml
table:
defaultHeadings: { rows: 1 }
contentToolbar:
- tableColumn
- tableRow
- mergeTableCells
- tableProperties
- tableCellProperties
- toggleTableCaption
```

### Actual behavior

Nothing

### Screenshots

## Versions

15.0.2

Start from the RTE configuration used by the TYPO3 package and compare its table setup with the YAML shown in the issue. The work is done when the floating table toolbar exposes column, row, merge, table-property, cell-property, and caption actions on TYPO3 v12.4.
