TableCellCollection 类
封装 TableHeaderCell 和 TableCell 对象的集合，这些对象组成了 Table 控件中的一行。无法继承此类。
**命名空间:**System.Web.UI.WebControls
**程序集:**System.Web（在 system.web.dll 中）
语法
声明
Public NotInheritable Class TableCellCollection
Implements IList, ICollection, IEnumerable
用法
Dim instance As TableCellCollection
public sealed class TableCellCollection : IList, ICollection, IEnumerable
public ref class TableCellCollection sealed : IList, ICollection, IEnumerable
public final class TableCellCollection implements IList, ICollection,
IEnumerable
public final class TableCellCollection implements IList, ICollection,
IEnumerable
备注
使用此类以编程方式管理在 Table 控件中组成一行的 TableCell 对象集合。此类通常用于在 Table 控件中添加或移除一行中的单元格。
提示
Table 控件包含表示 TableRow 对象集合的 Rows 集合。每个 TableRow 表示表中的单独一行，并包含表示 TableCell 对象集合的 Cells 集合。这些 TableCell 对象表示表中的各个单元格。若要获取单个单元格，应首先从 Table 控件的 Rows 集合获取一个 TableRow。然后可以从 TableRow 的 Cells 集合获取一个 TableCell。
示例
下面的示例说明如何以编程方式填充 Table 控件。表示各单元格的 TableCell 对象通过 Cells 属性添加到表示各行的 TableRow 对象。
