除了可以通過類CL_SALV_EVENTS_TABLE的事件設置ALV的頁眉頁腳之外，還可以通過類CL_SALV_TABLE的方法SET_TOP_OF_LIST,SET_TOP_OF_LIST_PRINT,
SET_END_OF_LIST,SET_END_OF_LIST_PRINT這四個方法。頁眉頁腳的顯示可以設置顯示和打印時不一樣，打印時的頁眉頁腳通過方法SET_TOP_OF_LIST_PRINT和SET_END_OF_LIST_PRINT。
1. 聲明設置頁眉頁腳所需要的Layout的實例和變量。
DATA: lr_grid TYPE REF TO cl_salv_form_layout_grid,
lr_grid2 TYPE REF TO cl_salv_form_layout_grid,
lr_text TYPE REF TO cl_salv_form_text,
lr_action TYPE REF TO cl_salv_form_action_info,
lr_header TYPE REF TO cl_salv_form_header_info,
lr_label TYPE REF TO cl_salv_form_label.
2. 添加頁眉頁腳所需要的文本到Layout裏。
lr_header = lr_grid->create_header_information(
row = 1
column = 1
text = 'Header Information'
).
lr_label = lr_grid->create_label(
row = 2
column = 1
text = 'Label'
).
lr_action = lr_grid->create_action_information(
row = 3
column = 1
text = 'Action Information'
).
lr_text = lr_grid->create_text(
text = 'text'
row = 4
column = 1
).
gr_table->set_top_of_list( lr_grid ).
lr_text = lr_grid2->create_text(
text = 'end of page'
row = 1
column = 1
).
3. 使用方法SET_TOP_OF_LIST設置頁眉
gr_table->set_top_of_list( lr_grid ).
