JTable header not showing

Question

JTable header not showing...

My JTable header wont show even if add it into a container like JScrollPane...tell me why is it happen and how can i fix it or debug i

Answer 1

Start by removing

panel.add(table.getTableHeader());

The JTable is designed to add it's header to the JScrollPane. An instance of a component can only belong to a one parent/container, the above line is removing it from the scrollpane

Also, change this...

panel.add(table);

To

panel.add(scrollPane);
