Quick and dirty, eh? How about a piece of aluminum plate bolted to a piece of 2" round aluminum bar? Can be held in the vice on your mill, and set at any angle with a protractor. The table was set into the bar so I could rotate it 90 deg. I was still working on it when I took the pics, so surface is a bit rough. I was experimenting with flycutters. I have since smoothed the table and drilled a pattern of holes for clamp screws. I don't use it every day, but it works when I need it.
