What is the best way to fix a leg back on a kitchen table?

Like most tables of this kind, a nut and bolt system is used, but the bolt has worked itself out of the leg, creating an enlarged hole in the process. Once I’ve plugged the whole with a dowel I can’t see a way of driving the bolt back into the leg without a slot for a screwdriver at the end of it. Can one glue bolts back into legs perhaps? Any ideas appreciated, we'll be eating off the coffee table tonight!
