Lifetime makes tables with adjustable heights. I have 2 that are 2 ft x 4 ft and 2 that are about 2 ft x 17+".
I do use the larger tables put together when I am squaring up quilts and doing larger work. I love that they are adjustable so it is easy to cut on them. I also love that they cam be lower so friends can come over for sew days. Oh yeah, I have used them for parties for extra tables.
They store really well too.
I bought a smaller table on sale at an office supply store: Office Max or Staples or Office Depot. the larger tables were either Costco or Sam's Club.
