Hi.
Well try this:
gr_columns->set_optimize( 'X' ).
gr_column ?= gr_columns->get_column( 'LCKBETR' ).
gr_column->set_short_text( ' ' ).
gr_column->set_medium_text( ' Landed Cost w/o Mkt'' ).
gr_column->set_long_text( ' ' ).
gr_table->display( ).
With this you should reach your goal.
Hope to help.-
Bye
