Does Firefox support position: relative on table elements?
When I try to use position: relative / position: absolute on a <th> or <td> in Firefox it doesn't seem to work.
Easy and most proper way would be to wrap the contents of the cell in a div and add position:relative to that div.
example:
<td>
<div style="position:relative">
This will be positioned normally
<div style="position:absolute; top:5px; left:5px;">
This will be positioned at 5,5 relative to the cell
</div>
</div>
</td>
That should be no problem. Remember to also set:
display: block;
