Some folks have used pieces of PVC pipe cut to appropriate length to raise the height of the folding tables so they are right for cutting without bending over. If you're thinking about using the table shown on the left side of your pic you could do something like that. The idea is to cut the PVC pipe so that when the bottom part of the legs are slipped into it, it raises the table to appropriate height for the person using it. Better than trying to cut on a table that is too low which is very hard on your back.
