I thought you were talking about the spacing outside the tables, not inside the tables like you are now showing.
If you use an addon like firebug, you can find that it's being affected by blue.css, and in particular your second line:
HTML Code:
/* ~ CSS Tweaks ~ */
*{padding:0;margin:0;}
I can't see that other box, so I don't know what is up with it. I replied to someone else having that list issue and suggested he added "list-style-position: inside;" to the li description for his css.
