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 TOcl_salv_form_layout_grid,

?????? lr_text?????? TYPE REF TO cl_salv_form_text,

??????lr_action???? TYPE REF TOcl_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里。

??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 ).
