Remove Column Headers from a JTable in a JScrollPane

Question

Hi,
I'm just wondering how to remove the column headers from a JTable in a JScrollPane.

Answer 1

Here are two ways to do it, with different visual outcomes...
import javax.swing.*;
public class Test {
    public static void main(String[] args) {
        Object[][] rowData = {{"A", "B"}, {"C", "D"}};
        Object[] columnNames = {"col 1", "col 2"};
        JTable table1 = new JTable(rowData, columnNames);
        table1.getTableHeader().setVisible(false);
        JScrollPane sp1 = new JScrollPane(table1);
        JTable table2 = new JTable(rowData, columnNames);
        final JScrollPane sp2 = new JScrollPane(table2);
        JPanel contentPane = new JPanel();
        contentPane.add(sp1);
        contentPane.add(sp2);
        final JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setContentPane(contentPane);
        f.pack();
        SwingUtilities.invokeLater(new Runnable(){
            public void run() {
                sp2.setColumnHeader(null);
                f.setLocationRelativeTo(null);
                f.setVisible(true);
}
