nitsua I just played around with it abit.
Make sure you have put the necessary code at the bottom of the css for the stylesheet you are using:
Manage Styles > Modify Style > choose the style you want to Modify; go to the bottom and put the code in, then save it. Refresh your browser to see the changes.
If you want it to have a solid background color put this in your css:
.tablepad { background-color:#FFFFFF; padding:6px; border:1px solid #000000; }
Change FFFFFF to the background color you want
Replace 000000 with the border color you want
If you want that area to have a background image put THIS in your css instead:
.tablepad
{
background-image: url(http://www.smfboards.com/Themes2/userstyles/Camo/camobackground.png);
padding:6px;
border:1px solid #FFFFFF;
}
Replace my image url with your own
Replace FFFFFF with the border color you want
Example (with background and white border):
