What do I do to fix this?

3. I have never tried anything on stains on wood,

but I did find several options on Wiki-how. The most important tip is to try anything you plan to use on a place where it cannot be seen, like the underside of the table if it is finished like the top. I would be afraid to try some of these, but if the table is ruined, it is better than getting rid of it. (Another thing if all else fails is to buy a lovely tablecloth. )

I chose these ones because of how hard these stains are to remove, as well as having found these same techniques on other sites for other stains.

Good luck. And let us know if anything works for you. It is always good to hear how things work.
