Place a few drops of water on the wood glue until it is saturated.
Turn a hairdryer to the highest heat setting.
Hold the hairdryer over the wood glue to heat it. This will weaken its bond with the table.
Pry off the wood glue with a plastic paint scraper. Be careful not to nick or scratch the table. If the wood glue doesn’t come off, continue wetting and heating it until it softens enough to remove.
Sand the wood glue off if it still won't come off the table. Use fine-grit sandpaper and stop sanding once you reach the tabletop.
Wipe the table with a damp cloth and dry it completely.
