Is there such a thing as a folding ping pong table?

Yes, amazon has a ton of them. http://www.amazon.com/s?ie=UTF8&search-alias;=sporting&field-keywords;=folding%20ping%20pong%20table&page;=1

Yes, there are folding ping pong tables and you can get them in many sizes and materials. Here's a few links to get you started. Take a look at them and see which works best for your needs:

I would also check your local Craig's list to see if you can get one used. People get rid of them all the time.

I have a fold-up ping-pong table (Olympia WA) in excellent shape. It closes up--but it has its own legs. If you want this and live in Oly--of could pick it up, let me know privately.

yes there is such a thing. Check out your local sports store or even check online.
