using the following code, can’t manage to get the column headers to show..Added Jscroolpane as well,but no luck…

String[] col = {"COLA","COLB","COLC"};
Object[][] data = {};

DefaultTableModel model = new DefaultTableModel(data,col);


JTable table = new JTable(model);
JScrollPane scrollPane = new JScrollPane(table);

contentPane.add(table);
table.setBounds(295, 11, 512, 411);
contentPane.add(scrollPane,BorderLayout.CENTER);

Answer 1

This worked:

public static void main(String[] args) {
  String[] col = { "COLA", "COLB", "COLC" };
  Object[][] data = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9} };
  DefaultTableModel model = new DefaultTableModel(data, col);
  JTable table = new JTable(model);
  JFrame frame = new JFrame();
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  frame.getContentPane().add(new JScrollPane(table));
  frame.setVisible(true);
}
