Comment(by dustymugs):

 You don't.  You're assuming the table is a coverage.  How about if the
 user doesn't want a coverage, namely me.  I just want a width check, which
 has nothing to do with whether or not the tile falls perfectly in a
 coverage's grid.

 Therefore, you have to have a separate constraint.  A width constraint is
 just that, a width constraint.  Same goes with height.  A coverage tile
 constraint ensures that the width and height are correct because the tile
 having the correct width and height is critical to be part of a coverage.
