Review Comment:
This was using `RowData` to get the default values for every single column
and then replacing them, so if you passed a map with all existing columns
defined then the `RowData` call was completely pointless. I also had ambitions
of getting rid of `RowData`. I did end up getting rid of `rowMap` though.
