TableHeaderCell Class

Represents a heading cell within a Table control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public class TableHeaderCell : TableCell
public class TableHeaderCell extends TableCell
public class TableHeaderCell extends TableCell

The TableHeaderCell class represents a heading cell in a Table control. You can use the Text property to specify or determine the contents of the heading cell.

This class allows you to control how the contents of the heading cell are displayed. The alignment of the contents in the heading cell is specified by setting the HorizontalAlign and VerticalAlign properties. You can use the Wrap property to specify whether the contents of the heading cell wrap in the cell.

You can also specify how many rows or columns in the Table control are occupied by an individual heading cell. The RowSpan and ColumnSpan properties control how may rows and columns are used, respectively.

The following example demonstrates how to declaratively program a TableHeaderCell control.
