Adds properties specific to the TableCell control to the list of attributes to render.
Assembly: System.Web (in System.Web.dll)
The method overrides the base class's AddAttributesToRender method and first calls the base method and then adds the TableCell attributes corresponding to the RowSpan property, the ColumnSpan property and the AssociatedHeaderCellID property. If the AssociatedHeaderCellID property refers to a TableHeaderCell that can not be found, an HttpException is thrown.
The method is used primarily by control developers extending the functionality of the TableCell control.Notes to Inheritors
When overriding the method in a derived class, be sure to call the method of the base class so that the TableCell control attributes are properly rendered.
The following code example demonstrates how to override the method in a custom server control so that a custom title attribute is rendered for each cell.
