Now you are talking about something completely different, how to handle
a sparse table in CSS as opposed to a dense table.  Dealing with that
in CSS is going to require considerably more than what you've got here.
CSS might benefit from a method of handling sparse tables, but 
you'll need to define display properties for the sparse counterparts of
the dense table elements, define how they interact with other display
types, et cetera.

Sparse tables are certainly a chicken and egg type situation in that
implementation will need both markup and presentation defined for it
before it can be used, but until they are available, I doubt if there will
be much demand for them as they can be simulated with existing
markup and style.
