I baste larger quilts on my kitchen island. It's only 3 feet wide, so this would work on a table too. I drape it over one end, use blue painters tape to get the backing part on the island smooth, drape over the batting, smooth it, then the quilt top draped on top. I don't worry about the stuff hanging off the edges. Then I pin baste the part that's smooth. Then I scooch it all over to another part of the sandwich, and go through the same steps. I rarely have had any problems on the back. If I had to baste on the floor, I wouldn't be able to do it.
