CSS/Table Border Help

I am working on building my own BBS system, but I like the feel of the thin borderline around the table like UBB.

Here is an example of what I mean:

I can't seem to figure out how they are doing it. I looks clean which is the feel I am looking for. Plus it seems to work in both IE and Netscape.

any thoughts?

Nested tables. First table has bgcolor='#000000' (aka black) and cellspacing/cellpadding='0'. Second table, which holds the content (e.g. header text 'forum', 'posts' and 'last post') has cellspacing='1'. So, 'between' each of the cells in the content table appears a 1px black line (actually the background colour of the container table), which looks like a border.

Hope that's what you meant anyway.

Got it to work.. Thanks...
