OO实现ALV TABLE 七：ALV的选择功能
1. 首先我们要取得类CL_SALV_SELECTIONS的实例。
DATA lr_selectionsTYPE REF TO cl_salv_selections.
lr_selections = gr_table->get_selections( ).
2. 设置选择模式。
lr_selections->set_selection_mode(if_salv_c_selection_mode=>row_column ).
3. 选择行
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. 选择列
DATA lt_column TYPEsalv_t_column.
APPEND 3 TO lt_row.
APPEND 4 TO lt_row.
lr_selections->set_selected_rows( lt_row ).
5. 选择一个单元格
DATA ls_cell TYPEsalv_s_cell.
ls_cell-row = 7.
ls_cell-columnname = 'CITYFROM'.
lr_selections->set_current_cell( ls_cell )
6. 选择多个单元格
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_cellTO lt_cell.
lr_selections->set_selected_cells( lt_cell ).
