If you use one of those white plastic tables (Walmart, etc), you can raise the it to the proper height with pvc pipe. Cut to length that works for you and insert each table leg into the pipe. Lowe's has precut pieces with a "finished" edge that are, I think 12" long. I forget what they are called, but are in the plumbing dept; good if you're going to use them on a finished floor.</https:>
