Isolated ground receptacles have the same 3 conductors as standard ones, but the ground conductor isn't bonded to the chassis the way a standard one is. Where the mounting ears on a standard three prong outlet are connected to the ground circuit, the isolated ground ones are not.
So you still have the safety features of a regular outlet, but the box it's screwed into is not part of the circuit (and in this case, the table remains isolated from the circuit as well).
