Delete Cell leaves a wrong rowspan

[Tobiasz Cudnik]

Delete Cell leaves a wrong rowspan.

1. Use following content:

   <table border="1" cellpadding="1" cellspacing="1" style="width: 500px; ">
   	<tbody>
   		<tr>
   			<td>
   				1</td>
   			<td>
   				&nbsp;</td>
   		</tr>
   		<tr>
   			<td>
   				2</td>
   			<td colspan="1" rowspan="2">
   				&nbsp;</td>
   		</tr>
   		<tr>
   			<td>
   				3</td>
   		</tr>
   	</tbody>
   </table>
   

2. Delete any of the left column's cells (labeled with 1, 2 or 3).

Result: The table has 2 rows and rowspan=2 on the second one (which is wrong).

These is almost the same TC:

1. Insert below

   <table border="1" cellpadding="1" cellspacing="1" style="width: 500px">
   	<tbody>
   		<tr>
   			<td rowspan="3">&nbsp;</td>
   			<td>&nbsp;</td>
   		</tr>
   		<tr>
   			<td>&nbsp;</td>
   		</tr>
   		<tr>
   			<td>&nbsp;</td>
   		</tr>
   	</tbody>
   </table>
   

2. Remove one of single cells.

Rowspan set to 3 stays.
