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 ).

cl_salv_column_table: related to methods/attributes applicable for specific column only(one at a time).

cl_salv_columns_table:related to methods/attributes applicable for more than 1 column.
