Xhtml strict - get 100% height of parent table

hi ladies and gents!

i think / hope one of you can fix my problem :slight_smile: or give me a hint.

i did a 3 col layout which is made out of tables… i know you hate tables but i did it with tables because of the browser comp. so… the left and right col has longer content than the center col. in the center col i got another table and this should have the height of the parent tables… normal html height=“100%” did the job. so now is there a solution for this?

thanks in advance!
