The idea with TableBuilder is that you can build a CellTable with any table
structure, using row spans, column spans, and Cells wherever you want.  I
haven't even started on the API, but at a high level, you will be given a
row value and a TableBuilder, and you render 0 or more rows that represent
the value into the TableBuilder.  In the simplest case, you render a single
row with some columns, each containing one Cell that maps to a field in the
row value.  However, you can do any of the following:

   - Create "expandable rows" by rendering multiple rows to represent the
   row value and index all but the first row
   - Insert a group header by making the first row span all columns
   - Create an error row beneath the rendered row to display an error
   - Insert multiple Cells within a column

I working on the fixed headers now, so I won't even begin work on
TableBuilder until May, with a goal to finish by the end of June.
