You might ask the Web Standards Group for some help - it's where I go when I get into a bind - their mail list is truly excellent reading.
Edit: Actually, if I had to do this I would probably use lists...
<td>
<ul>
<li><a href='#'>Some text stuff</a></li>
<ul>
</td>
Then set my padding/margins to fill up the table cell (if that was possible)...
