重點備註：1.在輸出內表中增加欄位FIELD_STYLE TYPE LVC_T_STYL

                    2.設定STYLE_FNAME = 'FIELD_STYLE'.  如果不進行此步驟操作，這對單元格的屬性控制不會生效

在使用ALV顯示列表的過程中，我們可以使用IT_FIELDCAT引數設定某一個欄位的可編輯狀態。但是，要設定具體的單元格的可編輯狀態對於對ALV不是很瞭解的人來說是一個頭大的問題。
      具體單元格可編輯狀態設定的主要思想：首先通過EIDT引數設定列為可編輯狀態；其次對輸出內表進行迴圈將不需要編輯的行設定為不可編輯狀態，如此單元格的可編輯屬性設定完畢。下面貼上簡要程式碼。

部分程式碼：
DATA: BEGIN OF ITAB OCCURS 0,
      ZQRFH_ICON TYPE STRING,
      ZLDATE TYPE ZLDATE,
      ZLUSR TYPE ZLUSR,
      K TYPE STRING,
      FIELD_STYLE TYPE LVC_T_STYL, " 為內表新增設定編輯狀態所需的欄位  
      END OF ITAB.

S_FIELDCAT-FIELDNAME = 'ZBQFS'. " 設定列可編輯
S_FIELDCAT-EDIT = 'X'.
APPEND S_FIELDCAT TO T_FIELDCAT.

DATA STYLELIN TYPE LVC_S_STYL.

LOOP AT ITAB.
    IF ITAB-ZXMDM = 'D' OR ITAB-ZXMDM = 'F' OR ITAB-ZXMDM = 'H'.
      STYLELIN-FIELDNAME = 'ZBQFS'. " 需要編輯的列名
      STYLELIN-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_DISABLED. " 設定為不可編輯狀態
      APPEND STYLELIN TO ITAB-FIELD_STYLE.
      CLEAR STYLELIN.
      MODIFY ITAB.
    ENDIF.
endloop.

X_LAYOUT-STYLE_FNAME = 'FIELD_STYLE'. " 將內表中的欄位名存入顯示格式

    EXCEPTIONS

      OTHERS             = 2.

控制單格的比較麻煩呢.要用OO了寫法了.

給個OO的例子吧.
