Remarks
Use the Scope property to get or set the scope of the TableHeaderCell control when it is rendered. The scope of the TableHeaderCell represents the cells that the header applies to. For complex tables, use the AssociatedHeaderCellID property, which provides more control over the specification of the relationship of header cells to data cells. The Scope property is used to make HTML tables more accessible by providing information about relationships between the cells and the headers.
For a list of the available table header scopes, see TableHeaderScope.
The value of this property is stored in view state.
