TableItemStyle 类
表示呈现为 TableRow 或 TableCell 的控件元素的样式属性。
**命名空间:**System.Web.UI.WebControls
**程序集:**System.Web（在 system.web.dll 中）
语法
声明
Public Class TableItemStyle
Inherits Style
用法
Dim instance As TableItemStyle
public class TableItemStyle : Style
public ref class TableItemStyle : public Style
public class TableItemStyle extends Style
public class TableItemStyle extends Style
备注
TableItemStyle 类表示呈现为 TableRow 或 TableCell 的控件元素的样式属性。通过分别设置 HorizontalAlign 和 VerticalAlign 属性，可以控制表项内容的垂直对齐和水平对齐方式。通过设置 Wrap 属性，还可以指定单元格的内容在到达单元格末尾时是否自动延伸到下一行。
此类提供对于创建 Table 控件中项的样式很有用的方法。可以使用 CopyFrom 和 MergeWith 方法复制另一个 TableItemStyle 的样式属性，或将其与从中调用此方法的 TableItemStyle 实例合并。
示例
下面的代码示例在 Table 控件中创建若干行，并且将 TableItemStyle 对象应用到每一行。

<head>
<script runat="server">
Private Sub Page_Load(sender As Object, e As System.EventArgs)

tableStyle.HorizontalAlign = HorizontalAlign.Center
tableStyle.VerticalAlign = VerticalAlign.Middle
tableStyle.Width = Unit.Pixel(100)
' Create more rows for the table.
Dim i As Integer
For i = 2 To 9
Dim tempRow As New TableRow()
