At our shop(factory), we need to run some 120v receptacles to 5 workbenchs the only way i see to do it is go across the floor with rigid then up one bench and then we have a pcs of 1" box that is welded to the top of each table to support a 1 1/2 inch air line is it within code to attach my emt to the 1" box tubing just under the air line. then i would be able to put an outlet at each table, that would be feed from a 20amp breaker in a panel on the wall.
jlhmaint, I have run into simular problems in garages and machine shops and usually make a column by bolting strut together then piping down the strut. It may work for you if your ceiling height is not too high.

now that i think about it no the tables are not secured to the floor, the tables are about 4x8 and are back to back in a line of 5 tables. they are made out of 2x2 box and are hard to move but not impossible. if conduit is ran from table to table do all tables have to be bolted to floor.

I would want the tables bolted to the floor to be certain that they dont get moved and break a conduit coupling or connector(especially since you are running emt between them) I dont see a problem with attaching to the 1"sq. tubing
I worked as a maintenance electrician for 7 years and with the knuckleheads that were operating the equipment there,I never used emt,only rigid.
