My solution for table wiggle was essentially the same as Jim's (see below) but I
used a strip of bicycle tubing instead of 3M tape.

| I took some of that 3M abrasive tape that you use on stair treads.  I
| stuck it on the upright tube of the table in the spot where the screw
| tightens down.  Now the screw (and related tightening device) clamps
| down onto the abrasive tape.  It does an elegant job of holding it
| without tying stuff on it or screwing things into the table or the
| walls.
