If you are creating the TableModel automatically from a set of values  with  new JTable Vector  Vector     perhaps it is easier to remove editors from columns   JTable table   new JTable my rows  my header    for  int c   0  c  lt  table getColumnCount    c          Class lt   gt  col class   table getColumnClass c       table setDefaultEditor col class  null             remove editor     Without editors  data will be not editable

You can override the method isCellEditable and implement as you want for example     instance table model DefaultTableModel tableModel   new DefaultTableModel           Override     public boolean isCellEditable int row  int column             all cells false        return false            table setModel tableModel     or    instance table model DefaultTableModel tableModel   new DefaultTableModel          Override    public boolean isCellEditable int row  int column             Only the third column        return column    3           table setModel tableModel     Note for if your JTable disappears  If your JTable is disappearing when you use this it is most likely because you need to use the DefaultTableModel Object     data  Object   columnNames  constructor instead     instance table model DefaultTableModel tableModel   new DefaultTableModel data  columnNames          Override     public boolean isCellEditable int row  int column             all cells false        return false            table setModel tableModel

You can use a TableModel   Define a class like this   public class MyModel extends AbstractTableModel        not necessary     actually isCellEditable   is false by default so you may omit it   see  http   docs oracle com javase 6 docs api javax swing table AbstractTableModel html   Then use the setModel   method of your JTable   JTable myTable   new JTable    myTable setModel new MyModel
