Stiga ping pong table is what I use. It's 2 pieces so also good for other games, substantial so you can lean on it, the table surface is really robust and resists scratches. Amazon says out of stock but it's worth the wait. Alternatives I found were $250+ and not rated to hold weight, or not folding, or incredibly heavy, etc etc. I have limited space and this one fits behind my couch against the wall and is virtually invisible.

6'x4', HEAVY. Two pieces so you have a smaller 3x4 if you want. I was looking at the small, light, quatrefolding, gaming tables and they were nearly $300US for something you couldn't put your weight on.
i was thinking of doing this but just ended up buying a mini table from amazon. i love it
