put div on bottom when the table resize

hi,
i have a table with a div inside when the page load the div is on bottom at 100%
the site have some menus that changes the size of the site without reloading
the page when the site grow that div is pushed to the down so far so fine.
but when the content change again to the previous/original/small size
the div dont´ stay on the bottom at 100%
the problem is when the height/width are changed in runtime without reload the
page the div can´t return to the bottom of the table.
there is some javascript function or something like that to put
the div on bottom again?
thanks a lot for your help
