Hi, Sharon. Thought your question might get more response over here and sorry that it didn't. I would begin by taking some paint thinner on a white rag, preferably cotton and checking a small area on the bottom of the table that does have finish on it. Check well to be sure that the paint thinner does not attack the finish. If it does not seem to, then go after the wax on top. You can also try WD-40 for this since it does a nice job on crayon marks on walls, but if the paint thinner attacks the finish, the WD-40 probably will too. Spray it on the rag, not the wood.
If the organic solvents do attack the finish, Plan B is to lay down a couple of layers of paper towels over the mark and then use a lightbulb as a heater. If you have a large Clip-on type lamp that uses regular household bulbs, that would be great. You might also have something like a mechanic's trouble light which is kind of like an extension cord except it has a socket and lightbulb on the end. Take the guard off the lightbulb if you safely can and used the heat from the bulb to melt the wax so it is absorbed into the paper towels. Be careful as you do not want to get the table so hot that the finish softens this way either. Keep the bulb moving slowly so any one spot does not get too hot. That's how I would do it--either method, depending on the test results. Good luck.
