I've used YUI more than once. It's pretty elaborate but for my purposes, I've just used their wizard (http://developer.yahoo.com/yui/grids/builder/ http://developer.yahoo.com/yui/grids/builder/) to set up the grid the way I wanted it and it's never given me any trouble. Plus, it works across pretty much across all browsers.
