Fixed table size

i have a website that im making, and its based inside a table. sometimes, the content makes the table higher than its supposed to be, because i set its height to like 45%, but it gets bigger when the info overrides the edges. is there a way to solve this?:*(

<table width="45%" height="200">

I think that might be what you mean

i think i did that backwards for what your looking for, so i guess you would do

<table width="200" height="45%">

that should do what you need
