If you want to do it "right" plug the 4 prong plug from the machine
into the 4 prong outlet in the table.  Trace the wiring in the table
to see what connects to the black and white wires going to the outlet.
that might be a power cord with a standard plug that goes into a wall
outlet, or it might come from something else.

The 2-wire plug and socket in the table are for a loop power supply
that normally sits on a shelf in the table.
