Right, for my new site I'm gonna use expandable tables because iFrames just suck santa's balls. For the edges, they're uneven because I'm using scanlines. So I can't use a 1px row for expanding with. If you don't know what I mean, look at this. If I did use the 1px row, it would just be the same scanline all the way down. Help?
your using a 3x3px block scanline pattern, so make it 3px tall instead of 1px tall when you slice and it should work for you
