TableCell.ColumnSpan Property

Gets or sets the number of columns in the Table control that the cell spans.

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

public virtual int ColumnSpan { get; set; }
<asp:TableCell ColumnSpan="Int32" />

Property Value

Type: System.Int32
The number of columns in the rendered table that the cell spans. The default value is 0, which indicates that this property is not set.

ExceptionCondition
ArgumentOutOfRangeException

The selected value is less than 0.

Use the ColumnSpan property to specify or determine the number of columns in the rendered table that the cell spans. For example, if you set this property to 2, the cell takes up two columns in the Table control.

The following code example demonstrates how to declaratively specify the ColumnSpan of a TableCell control. In particular, note how the last row's single cell spans three columns. For a complete, working code example, see the TableHeaderCell class overview topic.

<asp:TableCell AssociatedHeaderCellID="Column1Header Column2Header Column3Header"
ColumnSpan="3"
HorizontalAlign="Left">(2,0)
</asp:TableCell>
