TableItemPattern.ColumnHeaderItemsProperty 欄位

定義

識別可取得所有與資料表項目或儲存格相關欄位標頭的屬性。

public: static initonly System::Windows::Automation::AutomationProperty ^ ColumnHeaderItemsProperty;
public static readonly System.Windows.Automation.AutomationProperty ColumnHeaderItemsProperty;
 staticval mutable ColumnHeaderItemsProperty : System.Windows.Automation.AutomationProperty
Public Shared ReadOnly ColumnHeaderItemsProperty As AutomationProperty 

欄位值

範例

在以下範例中,會擷取一組自動化元素物件陣列,代表資料表的主要列或欄標頭項目。

在此範例中,展示屬性與列及欄標頭項目之間的 RowOrColumnMajor 關係。 然而,無論資料表的屬性如何 RowOrColumnMajor ,資料表都可以有列和欄標題。
