I've used both the iron method -- already suggested -- and also an ice cube(s). Lay a cloth on the table and add an ice cube(s) on top of it where the wax is. Let it sit there a couple of minutes until the wax hardens/freezes and it should pop right off. Should you use this suggestion -- once the wax is up, make sure the table top is dry and put a small spot of mayonnaise on a dry cloth and rub it on the spot. Again, let it absorb a bit and use a dry cloth to buff up where the mayo was.
