People tried this, it's the most well known way. I haven't tried it, but I suspect that it doesn't work well. Why? There's no existing product on the market, despite the fact that it's a well known method. My guess that it's hard to level the table that way. Also, there's the patent on which the Tree Table is based (expired in 2001). Why was the patent made, if an alternate solution was easy?
