These are my two favorite providers of portable tables for close-up card magic.
My table criteria are minimalist.
- Portable when collapsed
- Adjustable height
- Large enough surface for card tricks (e.g. 14" x 24")
- Reasonably easy to move around when opened
- Easy setup & takedown
Doug Ries at Flipdisc sells nice tables. Here is a list of most of them: http://flipdisc.com/mmp.htm
I particularly like the side table http://flipdisc.com/side_table.htm because it is compact and unobtrusive.
Doug at Flipdisc is a super friendly guy and provides terrific customer service.
Another provider of tables is Showtime Magic Products https://squareup.com/store/showtime-magic-products.
I ordered their Ultimate Table Base-Compact and Large 2-in-1 Shelf/Tabletop, because its black base is more appropriate for my style.
Showtime's customer service was also good.
