Just a thought...
but what about an inexpensive photographers monopod? They come in a wide variety of sizes and price points and they all have a 1/4"x20 threaded screw that could be attached to the bottom of a table quite easily.
And of course, you can use it for photography when it's not holding up the table.
You Reading This: Stop
Don't just stay tangled up in your life.
Out there in some river or cave where you
could have been, some absolute, lonely
dawn may arrive and begin the story
that means what everything is about...
William Stafford 1914-1993
