Use denatured alcohol ---
Apply enough alcohol to a clean rag to dampen it well (not drippy).
Lightly rub the alcohol-soaked rag over the paint spots to remove. Rinse cloth, resoak, and repeat as needed. Dry the spot with a clean, dry rag when finished.
Or try ammonia, applying it the same as alcohol. Rinse well and dry.
I've had good results with both.
Either sand it off or get a commercial paint remover. You don't say if this is just a spot in an area or the whole table top. That would help.
Take a look at these ideas! Good luck to you!
Sometimes you can just gently scrap it off depending on what the table is finished with.
