1. 首先我們要取得類CL_SALV_SELECTIONS的實例。
DATA lr_selections TYPE REF TO cl_salv_selections.
lr_selections = gr_table->get_selections( ).
2. 設置選擇模式。
lr_selections->set_selection_mode( if_salv_c_selection_mode=>row_column ).
3. 選擇行
DATA lt_row TYPE salv_t_row.
APPEND 3 TO lt_row.
APPEND 4 TO lt_row.
lr_selections->set_selected_rows( lt_row ).
4. 選擇列
DATA lt_column TYPE salv_t_column.
APPEND 3 TO lt_row.
APPEND 4 TO lt_row.
lr_selections->set_selected_rows( lt_row ).
5. 選擇一個單元格
DATA ls_cell TYPE salv_s_cell.
ls_cell-row = 7.
ls_cell-columnname = 'CITYFROM'.
lr_selections->set_current_cell( ls_cell )
6. 選擇多個單元格
DATA lt_cell TYPE salv_t_cell,
ls_cell TYPE salv_s_cell.
ls_cell-row = 5.
ls_cell-columnname = 'CITYFROM'.
APPEND ls_cell TO lt_cell.
ls_cell-row = 6.
ls_cell-columnname = 'CITYFROM'.
APPEND ls_cell TO lt_cell.
lr_selections->set_selected_cells( lt_cell ).
