- 使用REUSE_ALV_GRID_DISPLAY_LVC显示ALV时，可以将列、行或者具体的某个单元格设置成可编辑能输入状态.
- 列可编辑只要将Fieldcat中的字段edit设置成‘X'，整列就变成能输入的了，LVC_S_FCAT-EDIT = 'X'.
GT_FIELDCAT TYPE LVC_S_FCAT. gW_FIELDCAT LIKE LINE OF GT_FIELDCAT.... GW_FIELDCAT-EDIT = 'X'. APPEND GW_FIELDCAT-EDIT TO GT_FIELDCAT. - 整个ALV可编辑 ，Layout的字段edit设置成'X'。
gs_layout type LVC_S_LAYO.gs_layout-edit = 'X'. - 单元格不可编辑 。如果要让单元格变成可输入，需要在alv输出内表中多定义一个保存单元格style的字段(类型：lvc_t_styl )，然后填入style属性(可编辑或者是不可编辑)，最后还要在layout-stylefname中指定style的字段名。
- 内表结构中增加一个字段
TYPES:BEGIN OF ty_data,sel TYPE char1,style TYPE lvc_t_styl, "将该字段设置为保存编辑状态的字段END OF ty_data. - Fieldcat 赋值（ MC_STYLE_DISABLED：禁止输入、MC_STYLE_ENABLED:可输入。）
DATA:gw_edit TYPE lvc_s_styl,gt_edit TYPE lvc_t_styl.gw_edit-fieldname = 'SEL'. gw_edit-style = cl_gui_alv_grid=>mc_style_disabled."设置为不可输入 INSERT gwa_edit INTO TABLE git_edit.INSERT LINES OF gt_edit INTO TABLE gw_data-style. "给ALV内表结构赋值 - Layout赋值
DATA gs_layout TYPE lvc_s_layo.gs_layout-stylefname = 'STYLE'. "指定保存编辑状态的字段名 -
