            } 
        
        };
       table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
       Mdl1.addColumn("1st value");

        table.addMouseListener
                 (
                new MouseAdapter() 
                {
                    
            @Override
                    public void mousePressed(MouseEvent e) 
                  {
                    showPopup(e);
                  }
            
            @Override

                showPopup(e);
            }
                    
                    private void showPopup(MouseEvent e)
                    {
                        if(e.isPopupTrigger())
                        {
                            pop.show(e.getComponent(),
                       e.getX(), e.getY());
                            
                        }
                    }
                }
                );
    }
    public static void main(String[]args){
       new tbls();
    }
   private JTable table;
   private JScrollPane scrollPane;
}

i'm having a hard time to figure out how to put the isCellEditable to JMenuItem. i want to do is when i click the "edit 1st value" in the popup the 1st value column will be editable but the other 2 column will not be editable, when i click the "edit 2nd value" in the popup the 2nd value column will be editable but the 1st and 3rd column will no be editable same as the edit 3rd value.
I try this code: if(itmEditVal1.isSelected()){return column == 0;};
but nothing happens.
Any Suggestions or code sample would be appreciated :D

One option: use JCheckBoxMenuItem (to allow multiple selections) or JRadioButtonMenuItem (to allow a single selection, after the items have been added to a ButtonGroup).

Aside, all Swing constructors and methods should be invoked on the EDT. Not on the Main thread.
