A little help with tables?

I've been working on implementing some tables into my sig, and i'm getting the feel of tables. But I need some way to get two images inbetween 2 images. Here's what I mean;


The left nonsquished image is fine as it is. The upper square image represents my rotating avatar, that's fine too. The bigger square image represents my theme's sig picture. The bottom image (rotating sig) is the problem, I want to squish it inbetween the left and right images, but below the middle top image. Any suggestions?

You'll want to put the 2 smaller images within the row (and column) instead of separate rows, like this
