Place A Javascript Menu Inside A Cell Of A Table.

I´m trying to place a javascript navigation menu inside a cell of
a table in my page, the problem is that the constructor of the menu
object has parameters for menu positioning and size and when the
window is rezised the menu stands at the same position and with the
same size.

My question is: is there a way to modify those parameters
dinamically to match window size, and how is that made, or is there
another way to include that menu using a table for page layout.
