 property System::String ^ VAlign { System::String ^ get(); void set(System::String ^ value); };
public string VAlign { get; set; }
member this.VAlign : string with get, set
Public Property VAlign As String

属性值

HtmlTableCell 的实例所表示的单元格的内容的垂直对齐方式。 默认值为 Empty,表示未设置此属性。

注解

VAlign使用 属性可以指定由 类实例表示HtmlTableCell的单元格中内容的垂直对齐方式。

注意

设置此属性仅影响类实例表示的 HtmlTableCell 单元格。 若要对表中整行的单元格应用相同的垂直对齐方式,请设置 VAlign 由 类的实例表示的行的 HtmlTableRow 属性。

下表列出了可用于此属性的值。

“值” 说明
Top 将单元格的内容与单元格的上边缘对齐。
Middle 对齐单元格中心单元格的内容。
Bottom 将单元格的内容与单元格的下边缘对齐。

注意

还可以将 BaseLine 用作此属性的值。 但是,并非所有浏览器都支持此功能。
