The was exactly one of the ideas I was going to post but I was unsure of the setup. Although an automotive jack may not be the best idea since they have such a small area of contact. There are other types of hydralic jacks that have a much larger flat surface area, a motorcycle jack comes to mind, however it would seem a bit pricey to me to just buy one for that purpose. If you do use a automobile jack, try to put one at each corner, also do not jack the table up, just raise the jack or even jackstand until it touches the table but does not lift it. However not everyone has a bunch of car jacks lying around like I do so this will depend on what you have.
