<if> conditional for particular row in a table

[sparklywater]

I'm not sure what you mean. This is the query I am using to fetch the rows:

SELECT post.postid, post.pagetext as pagetext, post.userid, post.username, post.dateline AS date, thread.forumid, thread.title as thread_title, thread.threadid, forum.forumid, forum.title as forum_title, thread.replycount as replies, thread.views as views
FROM " . TABLE_PREFIX . "thread AS thread
INNER JOIN " . TABLE_PREFIX . "post AS post on (post.postid = thread.lastpostid)
INNER JOIN " . TABLE_PREFIX . "forum AS forum on (thread.forumid = forum.forumid)
WHERE post.visible = '1' AND thread.visible = '1' AND open = '1'
ORDER BY date DESC
LIMIT $sel_limitlowerminus1,$perpage

And this is the code for constructing the rows:

<tr> 
 
<td alt="Go to last post in thread '$WQfield[thread_title]'" title="Go to last post in thread '$WQfield[thread_title]'" style="cursor:pointer;" onclick="window.location.href='$vboptions[bburl]/showthread.php?$session[sessionurl]p=$WQfield[postid]'" class="alt1" WIDTH="42%" VALIGN="middle" align="left"><div style="font-size: 11px"><a href="$vboptions[bburl]/showthread.php?$session[sessionurl]p=$WQfield[postid]"><b>$WQfield[thread_title]</td><td align="center" class="alt1" WIDTH="23%" VALIGN="middle"><span style="font-size: 11px">$WQfield[date]</span></td>

<td alt="View profile of $WQfield[username]" title="View profile of $WQfield[username]" style="cursor:pointer;" onclick="window.location.href='$vboptions[bburl]/member.php?$session[sessionurl]u=$WQfield[userid]'" align="center" class="alt1" WIDTH="19%" VALIGN="middle"><div style="font-size: 11px"><a href='$vboptions[bburl]/member.php?$session[sessionurl]u=$WQfield[userid]'><b>$WQfield[username]</b></a></div></td>

<td align="center" class="alt1" WIDTH="8%" VALIGN="middle" align="center" style="font-size: 11px">$WQfield[views]</td>

<td onclick="who($WQfield[threadid]); return false;" alt="View who has posted in thread '$WQfield[thread_title]'" title="View who has posted in thread '$WQfield[thread_title]'" align="center" class="alt1" WIDTH="8%" VALIGN="middle" align="center" style="font-size: 11px; cursor:pointer"><a alt="View who has posted in thread '$WQfield[thread_title]'" title="View who has posted in thread '$WQfield[thread_title]'" href="misc.php?do=whoposted&amp;t=$WQfield[threadid]" onclick="who($WQfield[threadid]); return false;">$WQfield[replies]</a></td>

</tr>

Basically I want to be able to add something to a particular row of that table.
