ABAP WEB_DYNPRO 中调用什么方法可以修字段属性？

可以看一下下面的代码， 其中 GDS_VERIFY 的结构中要有CELLSTYLES TYPE LVC_T_STYL,"设置可编辑
*&---------------------------------------------------------------------*
*& Form FRM_SET_EDIT_FLAG
*&---------------------------------------------------------------------*
* flag 0 可修改 1 不可修改
*----------------------------------------------------------------------*
FORM FRM_SET_EDIT_FLAG .
DATA FIELD_STYLE TYPE LVC_S_STYL.
CLEAR:GDS_VERIFY,FIELD_STYLE.
READ TABLE GDT_VERIFY INTO GDS_VERIFY WITH KEY FLAG = 1.
IF SY-SUBRC = 0.
FIELD_STYLE-FIELDNAME = 'ZPZLX'.
FIELD_STYLE-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_DISABLED.
INSERT FIELD_STYLE INTO TABLE GDS_ZSD012VERIFY-CELLSTYLES.
MODIFY GDT_VERIFY FROM GDS_VERIFY TRANSPORTING CELLSTYLES WHERE FLAG = 1.
ELSE.
CLEAR:GDS_VERIFY,FIELD_STYLE.
READ TABLE GDT_VERIFY INTO GDS_VERIFY WITH KEY FLAG = 0.
IF SY-SUBRC = 0.
FIELD_STYLE-FIELDNAME = 'ZPZLX'.
FIELD_STYLE-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENABLED.
INSERT FIELD_STYLE INTO TABLE GDS_VERIFY-CELLSTYLES.
MODIFY GDT_VERIFY FROM GDS_VERIFY TRANSPORTING CELLSTYLES WHERE FLAG = 0.
ENDIF.
ENDIF.
ENDFORM. " FRM_SET_EDIT_FLAG
