I have tables and they are set up like this:

<TABLE>
<TR>
<TD WIDTH=20%>&nbsp;</TD>
<TD WIDTH=60%>&nbsp;</TD>
<TD WIDTH=20%>&nbsp;</TD>
</TR>
</TABLE>

However, the middle frame only expands to fit what content is inside it, not how wide the browser is.

How can I make it so it is always the same size even if there is no content in it?
