Problem with table spacing...

Question

I cant seem to find why the is a space btween two tables. If I have table1 with all my goodies in it(tr's/td's) and add a second table below it, it will leave a space between the two tables at runtime. I tried using the 'margin-bottom'/'margin-top' attribute but even if it's on 0px it still leaves the space but when I increase the px, the space grows.

What can the cause be of this space between the two tables?

thanks,
