Resize forum listing tables on forum homepage

[muan]

Hope someone can help here, I have tried looking but can't find the answer !

All I am after doing is reducing the width of the 'Last Post' column on the forum homepage in the skin I'm working on. The posts I've read seem to suggest that the column sizes / percentages are set in the forumhome_forumbit_level1_post / nopost templates but I can't see anything in there referring to anysuch values.

Running VB 3.7.0 Release Candidate 1

Here is my forumhome_forumbit_level1_nopost template

<tbody>
<tr>
<td class="tcat" colspan="<if condition="$vboptions[showmoderatorcolumn]">6<else />5</if>">
<if condition="$childforumbits">
<a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumbit_$forumid')"><img id="collapseimg_forumbit_$forumid" src="$stylevar[imgdir_button]/collapse_tcat{$collapseimg_forumid}.gif" alt="" border="0" /></a>
</if>
<a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]">$forum[title]</a>
<if condition="$show['forumdescription']"><div class="smallfont">$forum[description]</div></if>
<if condition="$show['subforums']"><div class="smallfont"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div></if>
</td>
</tr>
</tbody>
<if condition="$childforumbits">
<tbody id="collapseobj_forumbit_$forumid" style="{$collapseobj_forumid}">
$childforumbits
</tbody>
</if>

Thanks in advance if anyone can help me out :)
