Are you sure that a suitable table can't just be bought off-the-shelf?
Anyway, to build the control:
You need a microcontroller with CAN bus to read the commands.
You need some output from the microcontroller to the servos -- I'd suggest an UART speaking RS-485, although specifics depend on the servo.
Then you need the software development environment for the microcontroller you choose.
Unfortunately, most microcontrollers these days are surface-mount only, so "breadboard" might not be the right choice. You can find pre-built modules, though -- anything from the TI Stellaris development platform, to the Freescale mBED socket adapters, to the AVR-based Arduino line.
You also need a power supply of some sort to get the right voltage for the servos, and for the microcontroller. These can be bought off the shelf as "open frame power supplies" -- check a distributor like digi-key.com.
Btw: searching "mcu can" on digi-key returns 5808 different microcontrollers that might be suitable. Seems like something simple like an Atmega16M1 might be sufficient. See if you can find a reference/development board with it already soldered up.
If not, you might try an mBED 1768 module: http://mbed.org/handbook/mbed-NXP-LPC1768
