java-从jtable删除行

我想以摆动形式从jtable中删除一行
 

Jtable>>从Netbeans摇摆中自动拖动(Netbeans 8)

private javax.persistence.EntityManager entityManager;
private javax.swing.JButton jButton1;
private javax.swing.JButton jButton2;
private javax.swing.JScrollPane jScrollPane1;
private javax.swing.JTable jTable1;
private java.util.List<javaapplication1.Orders> ordersList;
private javax.persistence.Query ordersQuery;
private org.jdesktop.beansbinding.BindingGroup bindingGroup;

Jtable数据从MySQL数据库自动绑定

我只想从jtable中删除行而不是从数据库中删除

 private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    // TODO add your handling code here:

    int selectedRow =  jTable1.getSelectedRow();
    if(selectedRow!=-1)
    {
        try {
            jTable1.remove(selectedRow);
            jTable1.revalidate();
        } catch (Exception e) {
            e.getMessage();
        }

    }
} 

解决方法:

在这一行：

jTable1.remove(selectedRow);

此remove(int index)方法无法执行您认为的操作.它从Container类继承,旨在从给定容器中删除组件.

相反,您需要使用TableModel并从中删除选定的行.由于您使用的是matisse(NetBeans的GUI Builder),因此连接到表的表模型将是DefaultTableModel的实例,因此您可以执行以下操作：

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    int viewIndex = jTable1.getSelectedRow();
    if(viewIndex != -1) {
        int modelIndex = jTable1.convertRowIndexToModel(viewIndex); // converts the row index in the view to the appropriate index in the model
        DefaultTableModel model = (DefaultTableModel)jTable1.getModel();
        model.removeRow(modelIndex);
    }
}

请看一下：
