範例

下列程式碼範例示範如何建立控制項 HtmlTableCell 的 HtmlTable 實例，並將資料表放在網頁上。請注意， HtmlTableCell 控制項的無參數建構函式如何用來建立 <td> 專案，而採用字串參數的多載建構函式會搭配常值字串「th」來建立 <th> 專案。

備註

使用此建構函式來建立和初始化類別的新實例 HtmlTableCell 。它可讓您建立 HtmlTableCell 物件，代表控制項中的 HtmlTable 儲存格。它通常用來建立 HtmlTableCell 物件，此 <th> 物件代表表格標題儲存格的元素。雖然您可以使用這個建構函式來建立 <td> 資料表資料格的元素，但您通常會使用無參數建構函式。

注意

雖然此建構函式可讓您指定要建立的儲存格元素，但元素 <th> 是唯一支援的儲存格元素。為了未來的相容性，此建構函式可讓您建立其他可能可用的 HTML 儲存格元素。
