Wow that's a cool table
I think I'd use one of those white cable conduits that people run along walls, run your cables down the back of the monitor, and from the table surface to the wall in a straight shot (that is, so that straight ahead it's invisble and you'd only see it from the sides).
Then just have the white conduit go straight down to the floor.
Barring that, you could just grab a white DVI cable and a white power cord (they exist), use some white velcro ties to make it look really clean and then just have it hang down like a normal cable. Computers have cables, as long as it's not getting in your way it's ok XD
