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 it.. I search through internet and all they saying is add container to your jtable, i did but still my header are not showing.

public void table(){



try{



        rs = stat.executeQuery("SELECT * FROM payments;");



        Vector<String> header = new Vector<String>();



        header.add("PAYMENT"); 

        header.add("AMOUNT");

        header.add("MODIFIER");

        header.add("DATE MODIFIED");



        Vector<Vector<Object>> data = new  Vector<Vector<Object>>();



        while(rs.next()) {



            Vector<Object> row = new Vector<Object>();



            row.add(rs.getString("description"));

            row.add(rs.getString("amount")); 

            row.add(rs.getString("remarks")); 

            row.add(rs.getString("date"));





            data.add(row);



        } // loop



        table = new JTable(data, header);



        JScrollPane scrollPane = new JScrollPane(table);



        panel.add(table);

        panel.add(table.getTableHeader());

        //panel.removeAll();

        //scroll.add(table);

        validate();



    }catch(Exception e){

        System.out.println("Error in table: "+e);

    }//try and catch



}

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);

Same problem I have face
You have to add the JTable to the JScrollPane then add JscrollPane to JFrame
e.g.

JTable table = new JTable();

JScrollPane scrollPane= new  JScrollPane(table);

frame.add(scrollPane);
