Pascal, I tried all of Sledgstones code as well and I too had the space. I ended up having to customize it for my site because I have so many hacks running.
What his code attempts is continue using cellspacing="1" overall for the template, but to override it in a few spots with the CSS code placement. You'll have to play with your template in order to get it looking right. It IS possible, don't give up. Take a look at mine.
