Firefox 3's handling of CSS table width

Ok, something has changed from FF2 to FF3.  My site had  a width of 100% assigned to a table.  The table would stretch out to fill its defined div.  Now the FF seems to reinterpret that instruction.  It collapses the width to only be as wide as the column headers which is only about 50% of the width of its div (which is itself about 80& of the screen width).

I need this width to be percentage based because my people use a range of screen resolutions.

I can't find any discussion about this.

Thank you.

Under what doctype? Using a html 4.0 transitional doctype will likely cause this from 2 to 3.

Also, how are you declaring this width? Are you doing something like:
<table width="100%">

or something like:
<table style="width: 100%">

The way you declare this will absolutely cause a change from browser to browser and version to version based on what doctype you define and better yet, if any at all.

Paste your full code and we can better asses this.

Level9Wizard, thanks for checking this out.  I've simplified the html and css down to just the essentials which result in this behavior.  This should make it easier to read.

I noticed that "http://www.w3.org/TR/html4/loose.dtd" wasn't included with the doctype declaration, but doing so destroys the layout in IE.  Not sure of what's going on behind the scenes with that.
