I have one of the folding tables like JoAnns sells that I use for my cutting table. It has casters. Is not adjustable. I want hubby to make it adjustable for me (or really, just even shorten it). Could be done relatively easily by putting the casters on either wood or metal legs that are of a slightly smaller dimension than the original table legs (assuming those tubes are hollow - and I think on this one they are). Then drill holes in various positions on each leg/support and use a long bolt/pin to secure them at the height you want. Now if I can move that project to a higher priority level on either my or DH's 'to do' list, I'd have it made!
