示例

下面的代码示例演示如何创建包含HtmlTableCell控件的HtmlTable控件实例，并将表放在网页上。请注意控件的无参数构造函数如何 HtmlTableCell 用于创建 <td> 元素，而采用字符串参数的重载构造函数用于文本字符串“th”来创建 <th> 元素。

注解

使用此构造函数创建和初始化类的新实例 HtmlTableCell 。它允许你创建一个 HtmlTableCell 对象，该对象代表控件中的 HtmlTable 单元格。它通常用于创建一个 HtmlTableCell 对象，该对象代表 <th> 表标题单元格的元素。虽然可以使用此构造函数为表数据单元创建 <td> 元素，但通常使用无参数构造函数。

备注

尽管此构造函数允许指定要创建的单元格元素，但 <th> 该元素是唯一支持的单元格元素。为了将来的兼容性，此构造函数允许你创建可能可用的其他 HTML 单元格元素。

下表显示了实例 HtmlTableCell的初始属性值。

properties	初始值
TagName	`tagName` 参数的值。
