      lt_style type lvc_t_styl.

if g_edit = ''.
  loop at gt_eban.
    clear lt_style[].
    clear ls_style.
    ls_style-fieldname = 'FIELDXX'. "设置字段
    ls_style-style = cl_gui_alv_grid=>mc_style_enabled."可编辑
    append ls_style to lt_style.

    gt_eban-l_style[] = lt_style[].

    modify gt_eban.
  endloop.
  g_edit = 'X'.

elseif g_edit = 'X'.
  loop at gt_eban.
    clear lt_style[].
    clear ls_style.
    ls_style-fieldname = 'FIELDXX'.
    ls_style-style = cl_gui_alv_grid=>mc_style_disabled."不可编辑
    append ls_style to lt_style.

    gt_eban-l_style[] = lt_style[].
    modify gt_eban.
  endloop.
  g_edit = ''.
endif.
4. 输出内表:
call function 'REUSE_ALV_GRID_DISPLAY_LVC'
    exporting
      i_callback_program       = sy-repid
      i_callback_pf_status_set = 'FRM_PF_STATUS_SET'
      i_callback_user_command  = 'FRM_ALV_COMMAND'
      is_layout_lvc            = gs_layout
      it_fieldcat_lvc          = gt_fieldcat[]  "'[]' is necessary
      i_save                   = 'A'
      it_sort_lvc              = gt_sort[]
    tables
      t_outtab                 = gt_output
    exceptions
      program_error            = 1
      others                   = 2.

5. 更新数据:
form frm_alv_command using ucomm type sy-ucomm
                     rs_selfield type slis_selfield.

  data: lr_grid type ref to cl_gui_alv_grid.

  call function 'GET_GLOBALS_FROM_SLVC_FULLSCR'
    importing
      e_grid = lr_grid.
  call method lr_grid->check_changed_data.
* rs_selfield-refresh = 'X'.
* rs_selfield-row_stable = 'X'.
* rs_selfield-col_stable = 'X'.
* read table itab index rs_selfield-tabindex.
