定义

获取 HtmlTableCell 对象的集合,这些对象表示在 HtmlTable 控件的某一行中包含的单元格。Gets a collection of HtmlTableCell objects that represent the cells contained in a row of the HtmlTable control.

public:
 virtual property System::Web::UI::HtmlControls::HtmlTableCellCollection ^ Cells { System::Web::UI::HtmlControls::HtmlTableCellCollection ^ get(); };
[System.ComponentModel.Browsable(false)]
public virtual System.Web.UI.HtmlControls.HtmlTableCellCollection Cells { get; }
member this.Cells : System.Web.UI.HtmlControls.HtmlTableCellCollection
Public Overridable ReadOnly Property Cells As HtmlTableCellCollection

属性值

HtmlTableCellCollection,它包含 HtmlTable 控件中某一行中的单元格。An HtmlTableCellCollection that contains the cells of a row in an HtmlTable control.

属性

示例

下面的代码示例演示如何使用Cells集合来循环访问由HtmlTableRow对象表示的行的单元格。The following code example demonstrates how to use the Cells collection to iterate through the cells of a row, represented by an HtmlTableRow object. 然后,将用新内容更新单元。The cells are then updated with new content.

注解

使用该Cells集合以编程方式访问HtmlTable控件中某一行的单元格。Use the Cells collection to programmatically access the cells of a row in an HtmlTable control. 您可以通过编程方式在集合中添加、删除和插入单元。You can programmatically add, remove, and insert cells in the collection.

备注

如果行中没有定义单元,则返回空HtmlTableCellCollection对象。If there are no cells defined in a row, an empty HtmlTableCellCollection object is returned.
