http://webfx.eae.net/dhtml/tablesort/tablesort.html does this in IE, and perhaps Mozilla. Have used it many places, very easy to use. -----Original Message----- I'll also want to eventually add sorting up/down of the columns based on value. I'm thinking of going the DOM approach rather than try to show/hide all those divs and layers (IE5+ and Netscape 6+ is fine).
