Not sure what tech has shown up in the last 5 years but if you’re wanting to use an A/C motor it will take a VFD and a 3 phase motor. You can feed the drive with 120/240 single phase but the motor has to be 3 phase. Not sure if a stepper or servo would be your better choice but I know there’s a company named Minarik that sells kits (motor & controller) and has a good tech support group. I would think there’s some type of flex coupling that would couple motor to the shaft on your table.
