John, can you elaborate what 
  • Expandable rows (really, a fully customizable table builder, probably post GWT 2.3)
means?

I'm currently working on adding groupability to a copy of celltable and its hierarchy. Will the fully customizale table builder be the solution I'm looking for? 

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.
