How do i make borders like this?

[Mitsuaki]

Ok, ive been messing with skin development and stuff to that nature. All is going well but i seem to have hit quite a large stump which i cant get over. What im wanting to do ultimately is add a 1 pixel thick black border around the cells on my board.

Now to acomplish this i set my "Table Border" color to black (#000000) via the style editor in admincp. It came out looking like...

Now that is fine... thats what i want it to look like. However i then went into my user cp and went to "Edit Options" and seen what else had happened. It changed the background color windows in user cp to black too. This effectivly makes it looks like there is no border...

So i went back to the site in the first "example" to see if they suffered from the same problem. But they dont... their background is fine, and still has a normal black border...

So im wondering, how can i do this? Cause i cant for the life of me figure it out. Im assuming its done quite easily... i just simply dont know how. Please any help is greatly appreciated!.

(ps. ive also tried setting my "Table Border" color to the color i want in the bg of my user cp, then adding the border code to the extra css field. This inturn fixes my usercp, but it then makes all my catagories have a border color of the usercp background color... i simply cant win =[.)
