Consider the following HTML: 

IE displays the background color of the second column blue, but Firefox does not.  My question for you CSS pros out there is:  Is the background-color style not supported on COL elements?  (or is there something I can do to make this work?) 

<table cellpadding=10>
   <col style="background-color:#0000FF">
   <td>should be window color</td>
   <td>should be blue</td>
