Any idea how to either remove the rust or at least smooth it down enough
that the friction isn't in impediment to adjusting the table height?


Electrolysis. Same method to clean up old hand planes. Requires a car
battery charger and a bath of electrolyte (washing soda I believe)

You will need to separate out the column and place it into the solution.

A bit of fun on a 5 foot tall floor mounted press - I can think of a
lot of other drill presses that would make that rather challenging - -

A hunk of 6" or 8" PVC drain pipe doesn't seem unreasonable. It may
take some time with a dinky car charger, though.
You also need a full length electrode - - - -

Rebars are cheap enough.
