Thank you for the feedback.
I'm leaning toward 48" wide by 30" in deep. That should give me enough room around the machine to add an enclosure later. I'm also planning to wire the table for power with a switch that supplies power to everything and a magnetic power switch for the router. I'll make it mobile so I can push it out of the way when it's not being used so it will make things easier if I just have one power cord to connect when I'm ready to use it.
