Structures_DataGrid addColumn() callback method change from 0.6.0 => 0.6.2 ?

I just upgraded Structures_DataGrid from 0.6.0 to 0.6.2 and noticed that some of my scripts broke. In 0.6.0 the array passed to the callback function of the addColumn() method includes a slew of FormBuilder values, including '__table'. My code currently depends on this to create a generic function to add 'Edit/Delete' links to DataGrid tables. Was the change in the data passed to the callback function for addColumn() intentional for version 0.6.2 or was it an accidental omission? Thanks. - Jamie
