The folding tables that Teresa linked are great...
Some things to think about:
They ARE flexible (no hammering eyelets on them), they can melt (no heat embossing directly on the table).
But... they do fold up and store away, so that may be a good option.
I have a 6 foot table that the legs fold up. It's the hard top, metal legs (banquet/office). Very sturdy. Also VERY heavy. It's tough to carry it by myself.
