The message
Obj << Add Row( {values, .....} )
is a valid message for the Display Object, Table Box
The message
Obj << Add Rows( ,n., ,At Start|At End|After(m)> | { list of ( column name = value ) pairs } ))
is a valid message to add rows to a data table.
Both messages allow for the adding of rows, but in different formats, since the objects are very different in functionality
