Your passion is commendable. I'll not go into the "a <li> is more semantic and accessible than a <td>" debate. I'll just say that 1) display:table-cell doesn't work in IE6/7 and 2) CSS's limitations make it annoying or impossible to achieve functionality that was easy with table layouts (eg mixing percentage widths with fixed widths, and vertical aligment).
