Column dragging with rowspan issue

[empatel96]

Hi,

I've got an issue with dragging a column when I have a rowspan set for any of the TD's.
<tr> <td>1</td> <td>7</td> <td>13</td> </tr> <tr> <td rowspan="2">2</td> <td>8</td> <td>14</td> </tr> <tr> <td>9</td> <td>15</td> </tr>

Notice how the cell with 9 doesn't stick to it's column but switches into other columns when dragging. And the same goes for other cells within the same row.

After Drag

The table will be used to create new columns dynamically and some will possibly have customised rowspans so I'm not sure about how to go about doing it
