I really need some help on this.

I have a general page template created that uses 3 table columns. The contents of the left column are sometimes longer than the contents of the middle and right columns depending on the page. In the middle column, I have a DIV copyright notice that I want to be positioned 10px up from the bottom of the middle column, regardless of page length. In the right column, I have the same situation for an image.

So, essentially I want these elements always positioned 10px up from the bottom of their respective cells. I can't seem to figure out how to do it without adding a whole new table row to the bottom of my pages. I just want to use CSS! Help!
