1、想要展示像Excel一样，应该选用这个FUNCTION.
REUSE_ALV_GRID_DISPLAY
REUSE_ALV_GRID_DISPLAY_LVC
2、这个是调用FUNCTION的例子。
gs_layout-colwidth_optimize = 'X'.
gs_layout-zebra = 'X'.
gs_layout-min_linesize = 10.
DATA: gv_title TYPE lvc_title,
gv_nums TYPE n LENGTH 7.
gv_nums = lines( gt_bseg001 ).
SHIFT gv_nums LEFT DELETING LEADING '0'.
CONCATENATE '查询到' gv_nums '条凭证行' INTO gv_title.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
i_callback_program = sy-repid
is_layout = gs_layout
i_grid_title = gv_title
it_fieldcat = gt_fldcat[]
i_save = 'X'
TABLES
t_outtab = gt_bseg001[]
EXCEPTIONS
program_error = 1
OTHERS = 2.
3、另一个FUNCTION调用示范
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
EXPORTING
i_callback_program = sy-repid
* i_callback_user_command = 'USER_COMMAND'
* i_grid_settings = gs_grid
is_layout_lvc = gs_layo
it_fieldcat_lvc = pt_fcat[]
it_events = gt_event[]
* it_event_exit = gt_event_exit[]
TABLES
t_outtab = pt_tab
* EXCEPTIONS
* PROGRAM_ERROR = 1
* OTHERS = 2
