ListObject.Change 事件

ListObject 控制項變更時發生。

命名空間:  Microsoft.Office.Tools.Excel
組件:  Microsoft.Office.Tools.Excel (在 Microsoft.Office.Tools.Excel.dll 中)

語法

'宣告
Event Change As ListObjectChangeHandler
event ListObjectChangeHandler Change

備註

如果 ListObject 控制項以執行程式或與使用者互動的方式進行變更時,即引發這個事件。

當儲存格在重新計算期間發生變更時,不會發生這個事件。

範例

下列程式碼範例會建立 ListObject 和 Change 事件處理常式。 若要引發 Change 事件,請將文字加入至 ListObject 中的一個儲存格,然後按 ENTER 鍵。

這是示範文件層級自訂的版本。
