That's what the Arcici Airhead, the Seismic Sink and the Vibraplane are all about, as well as a homemade platform using silicone-filled inner tubes in a sand/lead base I've seen. Depending on the type of table and if it has a suspension or not, it could make very good sense, although some may point out that other materials, like acryllic or the Bright Star sand-filled bases, may do a better job of damping/isolating from vibrations.
