如何在Java的NetBeans IDE中的JTable中将celleditor设置为false？

Question

1. 这是我的代码，没有错误
2. 在此代码中，可以编辑每个单元格

如何防止单元格被编辑？

我正在使用DefaultTable模型

    package TableModels;

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

    /**
     *
     * @author  DELL
     */
    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
         * initialize the form.
         * WARNING: Do NOT modify this code. The content of this method is
         * always regenerated by the Form Editor.

Q1.i看到很多评论要说

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

但是它如何在netbeans中利用它呢？

Q2。另一则评论

      table.setEnabled(false);

但是使用此设置会禁用整个行，是否没有单独选择行？

Answer 1

在您的initTables方法中，当您创建DefaultTableModel的实例时，只需创建一个匿名类并覆盖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"); 

}
