Probably just a change to the template. Look at the source code for that column:
HTML Code:
<td id="f380" class="alt1Active" align="left" onclick="window.location.href='forumdisplay.php?f=380';" onmouseout="this.className='alt1Active';" onmouseover="this.className='alt2Active';" style="">
other stuff
</td>
Just change yours to have the same effect.
To find the template to modify, do this - vboptions > General Settings > Add Template Name in HTML Comments > set to Yes . Then go back to your page and view the source code and you will see the name of the template called around your part of the code.
