I use the same thing on my site, but my hosting service has been ass lately, and you might not be able to get there. Anyway, here's the code to do it:
<td align="center" onclick="location.href='http://www.codebloat.com/'" onmouseover="this.style.backgroundColor='#CBDCEC';this.style.cursor='hand';" onmouseout="this.style.backgroundColor='#FFFFFF';">
<font face="verdana, arial, helvetica" size="1"><b><a style="text-decoration: none; color: 000000" href="http://www.codebloat.com/">home</a></b></font></td>
Basically, the code assigns a default background color along with a color to use when the cursor moves over it. This particular cell points to my home page, with the word "home" as the text link. Using the
onclick="location.href='http://www.codebloat.com/'" code makes the entire cell clickable, as opposed to just the text contained within it. I also tell the browser what cursor style to display when the user mouses over the cell; in this case, it's the standard hand cursor.
Unfortunately, Netscape has lousy support for CSS (cascading style sheets). I haven't used the latest beta builds of version 6, but if Adul says it finally works, that's music to my ears.
