Power table dynamic font size?

I want to set my cell text to auto shrink if it’s overflowing in my power tables. I don’t see a feature for this but I was thinking maybe changing the size on the configureCell extension script but I can’t figure out a way to determine if the cell is overflowing or not. Any ideas?

What if you use a fixed width font, determine the number of characters it would allow you to fit in the space and do a calculation on, total table size / number of columns to get a pixel width?
