Как установить celleditor false в JTable в netbeans IDE в java?

Question

1. Вот мой код, который не имеет ошибок
2. В этом коде можно редактировать каждую ячейку

Как предотвратить редактируемую ячейку?

Я использую DefaultTable модель

package TableModels; 

    import java.awt.event.ActionEvent; 
    import java.awt.event.ActionListener; 
    import javax.swing.table.DefaultTableModel; 

    /** 
    *

    */ 
    public class TableModels extends javax.swing.JFrame { 

     /** Creates new form TableModels */ 
     DefaultTableModel dtm; 

     String name; 
     String age; 
     String gender; 



     public TableModels() 
     { 
     initTables();  

     initComponents(); 

     initListener(); 
     } 

     /** This method is called from within the constructor to

Q1.i видел много обзоров сказать

  public boolean isCellEditable (int row, int column) 
      { 
       return editable; 
      } 

но как использовать это в NetBeans?

обзор Q2.Another увидел

 table.setEnabled(false); 

, но с помощью этой настройки вся строка не отключается ни одна строка выбирается индивидуально?

Answer 1

В вашем методе initTables при создании экземпляра DefaultTableModel, просто создать анонимный класс и переопределить isCellEditable

public void initTables() { 

    dtm=new DefaultTableModel(0,0) { 
     @Override 
     public boolean isCellEditable(int row, int col) { 
      return false; // every cell is not editable 
     } 
    }; 

    dtm.addColumn("Name"); 
    dtm.addColumn("Age"); 
    dtm.addColumn("Gender"); 

}
