WP e-Commerce CSS

I installed WP e-Commerce from Instinct but I am having trouble with the CSS for one of the tables. I am trying to adjust the table element widths on the sliding cart in my Sidebar, but there doesn’t seem to be anywhere to do this. I went into shopping_cart_functions.php and added hard-coded widths, but it only affected some of the rows and not all. Look at my table here:

It is all out of line, how do I adjust this? I tried their forums but no one is around to help.
