A DESCRIPTION OF THE REQUEST :
There is no simple way to make editable column headers for a JTable. The TableColumn class provides methods to get and set the header renderer, but there is no method to set a header editor. The only way to edit a column header is to subclass the JTableHeader class.

JUSTIFICATION :
Editing a column header is a common task. An easy method should be provided to allow developers to implement this functionality rather than the time consuming process of subclassing JTableHeader.
