Missing inside table borders

[scrappygirl]

I'm trying to change the colors on my gallery. I changed my border colors, but now there isn't an inside border in my tables. I'm sure it's right in front of me... my gallery is located at: www.scrappygirldesigns.com/ideagallery

Here's the silver.css I'm editing:

Not sure what your asking for here. Your site looks perfectly fine to me if I view it

[scrappygirl]

yes, it's fine. But I'd like to have a borderline in between each gallery. I can't seem to get one.

Your tableborder is the same color as the rest of your cells
