Hi
Aus der JavaDoc der Klasse JTable:
Note that if you wish to use a JTable in a standalone view (outside of a JScrollPane) and want the header displayed, you can get it using getTableHeader() and display it separately.
JTables haben nur dann automatisch einen Header, wenn sie innerhalb einer JScrollPane angezeigt werden.
