No tables, no absolute positioning (no positioning at all), no hacks(!), same height of all columns. The left and right columns have fixed width (150px), the middle one is elastic. Any (zero or non-zero) margin of the body may be used. It works (AFAIK) in any modern browser - I tested it in IE5/Win95, IE6/WinXP, Opera7/WinXP, IE5/Mac, Mozilla, Safari, and Camino. It won't work in old browsers poorly supporting CSS (like NN4, IE4 etc).
