This is a really cool idea that not too many people think off. We all know that LED up-lighting is the latest and greatest thing to hit wedding venues. Why not draw attention to the head table with up-up-lighting underneath the table. LED's are safe because they do no conduct any heat. Many of these lights can also be run wireless and without needing to be plugged into a wall outlet. You could illuminate and draw attention to head tables or even your wedding cake, or gift table!
