Question: I have overridden the isCellEditable() method of class JTable in my code to make the cells of my JTable non-editable but selectable, but the cells are still editable. How do I solve this problem?

```
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

public class A extends JTable{

    JFrame frame = new JFrame();
    Object data[][] = {{"1","Jahanzeb"},{"2","Ahmed"},{"3","Shaikh"}};
    String col[] = {"#","Names"};
    DefaultTableModel tableModel = new DefaultTableModel(data, col);
    JTable table = new JTable(tableModel);
    JScrollPane scroll = new JScrollPane(table);

    public static void main(String arg[]){
        new A();
    }

    public A() {

        table.addMouseListener(new Click());
         table.setModel(tableModel);
        frame.setSize(500,500);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(scroll);
        frame.add(table);
        frame.setVisible(true);
    }

    @Override
    public boolean isCellEditable(int row, int column){
        return false;
    }

    class Click extends MouseAdapter{
        public void mouseClicked(MouseEvent e) {
            if(e.getClickCount()==2)
                System.out.println(table.getSelectedRow());
        }
    }
}

```

Answer: 
I believe you need to override the isCellEditable() method of the TableModel rather than the JTable, like so:

```
public class NonEditableModel extends DefaultTableModel {

    NonEditableModel(Object[][] data, String[] columnNames) {
        super(data, columnNames);
    }

    @Override
    public boolean isCellEditable(int row, int column) {
        return false;
    }
}

```

It is also possible to simply override the method using an anonymous class.

```
 DefaultTableModel tableModel = new DefaultTableModel(data, col) {

    @Override
    public boolean isCellEditable(int row, int column) {
        return false;
    }
}

```

This question demonstrates how to perform the override inline, which is handy if you only need to instantiate the TableModel once:

You are adding another `JTable` in your code, you are confusing between the one extending and the other one added to the JFrame!

Add these invocations after fixing the above:

```
table.setFocusable(false);
table.setRowSelectionAllowed(true);

```
