Tabelle cell lost after style has been applied

[Ralf Pöhlmann]

1. Add a new table (2x3)
2. Enter some text in all cells beside the last cell in the middle row

foo|bar|test foo|bar|<LEAVE THIS CELL EMPTY> foo|bar|test

3. Select all
4. Apply style heading 1

--> The Empty cell is removed (TD is lost). It's now impossible to enter some text in this cell.

	<tbody>
		<tr>

			<td>

		</tr>
		<tr>
			<td>

			<td>

		</tr>
		<tr>
			<td>
				test</td>
			<td>

		</tr>
	</tbody>
</table>
