cl_salv_columns_table -> refers to the whole column set.

cl_salv_column_table -> refers to a single column and its attributes.

See the below code to understand.

DATA: lr_columns

TYPE REF TO cl_salv_columns_table,

lr_column TYPE REF TO cl_salv_column_table.

DATA: l_shorttext TYPE scrtext_s,

l_mediumtext TYPE scrtext_m,

l_longtext TYPE scrtext_l.

• l_ddic_reference type salv_s_ddic_reference.

• get columns' object

lr_columns = r_grid->get_columns( ).

************************************************************************

• settings valid for all columns *

************************************************************************

• optimize columns' width

• lr_columns->set_optimize( ).

TRY.

• column messageid

lr_column ?= lr_columns->get_column( columnname = 'MESSAGEID' ).

CATCH cx_salv_not_found.

exc_handler=>process_alv_error_msg( gd_salv_msg ).

ENDTRY.

l_mediumtext = 'Error message ID'(015).

l_shorttext = ' '.

l_longtext = ' '.

lr_column->set_medium_text( value = l_mediumtext ).

lr_column->set_short_text( value = l_shorttext ).

lr_column->set_long_text( value = l_longtext ).
