问题描述

我尝试对JTable标头进行分组,为此我想获得当前JTable的DefaultTableModel。但是当我试图像这样检索表模型时:

I tried to group JTable header and for that I want to get the DefaultTableModel of current JTable. But when I tried to retrieve the table model like this:

DefaultTableModel dm=(DefaultTableModel) tblTet.getModel();

它显示以下异常:

因为我使用的是JTableBeansBinding。

Because I am using JTableBeansBinding.

有谁知道如何解决这个问题(检索DefaultTableModel)?

Does anyone know how to solve this problem (for retrieving DefaultTableModel)?

推荐答案

根据,该类不扩展DefaultTableModel。相反,它实现了TableModel接口。这意味着你不能转换为DefaultTableModel,只能转换为TableModel:

According to the JavaDoc for BindingTableModel, the class doesn't extend DefaultTableModel. Rather, it implements TableModel interface. This means that you cannot cast to DefaultTableModel, only to TableModel:

TableModel dm=(TableModel) tblTet.getModel();
