public abstract class TableColumns
extends AbstractTableViewComponent

A low level Table component that renders the column headers in the table. This component must be wrapped by TableView.

The component iterates over all column objects in the ITableColumnModel and renders a header for each one of them using the renderer provided by the getColumnRender() method in ITableColumn. The headers are wrapped in 'th' tags by default.

Please see the Component Reference for details on how to use this component. [Component Reference]
