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.

Danke für deine hilfe.Muss ich das denn einzelet aufrufen.


center.add(table);
center.add(getTableHeader());
