Now I know that you can make 3-Col layouts with divs at least 2 different ways.

Way 1:
Using Margins in your css:

left col---------------
float:left

middle col---------------
margin: 0 200px 0 200px

right---------------
float: right;

OR..................

Way 2:
floating the left col left, then sounding the left and middle cols in a div and floating it left and then floating the right div right.

What other ways can you make a three column layout with out using tables?
