Why do some search engines show errors?

[patsy121105]

I needed to place tables onto some of my pages. On one page I had to reduce the height of some of these to the minimum. On my page it looks fine. On Explorer in preview it looks fine and also online using both Yahoo! and Explorer.
But online through Firefox it looks wrong. It has elongated itself. Why is this, please?
Thanks

It's the way that FireFox interprets the code. This is a common issue between IE & FF.
