Oh btdt :) here's what worked well for me. first take a plastic putty knife and gently scrape off as much of the excess wax as possible. These are available at pretty much any store for REALLY cheap ... we're talking 50 cents to a dollar, if you don't already have one.
Next take a blow dryer, set it on medium heat, aim it at the wax residue for a few minutes, when it melts wipe with a soft cloth or paper towel. Voila bye bye wax.
The blow dryer trick works really well for crayons on the wall too :) but for crayons on the wall you can set it at a higher temp :)
I wouldn't go too high a heat on the wood table though.
Good luck :)
