JTable Tutorial didn't specify how to add columns names when using the constructor:
JTable(int numberofRows,int numberofColumns) Well then use another constructor. For example:
DefaultTableModel model = new DefaultTableModel(...);
JTable table = new JTable( model );Also, I forgot to mention don't use AWT components in a Swing application. Canvas is an AWT component. Use JPanel instead.
