When you click to expand the single voices of the leftside menu it pushes the table on the right column to the bottom.
I have solved this problem in IE7 by declaring with:100% to the box containing the table. In IE6 I have declared for the #menulaterale (the leftside menu) position: absolute. This in fact solves the problem of menu and table but introduces another one! …… being setted on an absolute position the menu doesn’t enlarge the column in which it is. When all voices are exploded they don’t enlarge the entire left side so tha menu breaks the layout in the bottom position.
