I am looking for indoor/outdoor table tennis table that can be used as a normal table when not in use….large family dinners and so on.
The ones that I keep looking at have so much iron work around the legs, you wouldn’t be able to sit around it as a table.

Go to a salvage yard and buy an old pool table slate, should be pretty cheap. Build a brick centre for it to sit, say, 4’x4′?

Cheap and would look good.
