Table Size?
 

Is there a tool or something that will tell you the height of tables?

If you mean to measure the height of an HTML table, I usually apply a background color to the table, view it in the browser, print screen, paste in phosothop or fireworks and measure it there (if the table isn't too big to fit on the screen).

If the table is too big, I apply diferent background colors to rows and do the same.

Not sure if this will help, but I use a handy free little tool called screen measure to, er, measure stuff on my screen.

It won't tell you exact sizes with one click or anything, but if you want a quick simple way of measuring it's very useful.

Nice tool KG Gary, I'll start using it for a while |thumb Maybe I'll get rid of the "print screen" habit :)
