Now Rick is back and of course he wants his own cell. We need to decide how much of the row we will give him. I suppose 20% is fair. Make sure to adjust Ed's share also.
What we may want to do, just to keep the browser from guessing, is to actually leave that empty cell there and just put a blank space in it ( ). Normally for a simple table this isn't necessary, however as your tables become more complex, the less guesing the browser has to to, the better off you'll be.
