No, but it's an amusing idea. Next Big Thing Award is featuring Table Tennis Triples as a 2008 finalist, and you can see a bit of a three v three (ie six person) game in a video on the site. However, the table does not have to be circular, and you can put the modules together in other ways -- as above.
The site says: "Modular Table Tennis System (MTTS) allows 1-12 or more players to play table tennis with exciting new game configurations." Quite how it works with only one player is not explained. Perhaps you have to be an expert at lobs and have very fast legs.
On the other hand, there could be a future for a Wii version....
