Solution 1

You can use a TableModel.

Like this

Java

public class MyModel extends AbstractTableModel{

}

Then set the model into your JTable.

Java

JTable myTable = new JTable();
myTable.setModel(new MyModel());

Solution 2

Here is another way..

Java

JTable table = new JTable(){  
       public boolean isCellEditable(int row,int column){  
         Object o = getValueAt(row,column);  
         if() return false;  
         return true;  
       }  
     };

Solution 3

Its work as you want. After click the disable button cell editing will stop.

Java

public class TestTable {

    boolean flag = false;

    public void create() {
        JTable table = new JTable(2, 2) {

            public boolean isCellEditable(int row, int column) {
                if (flag) {
                    return false;
                }
                return true;
            }
        };
        JFrame f = new JFrame();
        JButton button = new JButton("Disable");
        button.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e) {
                flag = true;
            }
        });
        f.setLayout(new FlowLayout());
        f.add(new JScrollPane(table));
        f.add(button);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            public void run() {
                new TestTable().create();
            }
        });
    }
