我正在尝试添加＆＃34;添加＆＃34;按钮到我的AbstractTableModel。然后它会弹出一个表格供用户输入个人电脑的IP地址，然后点击＆＃34;添加＆＃34;。我只是停留在如何动态地向表中添加新行（单元格）的部分。我在这里找到了几个例子，所有这些都没有帮助我。

忘记按钮操作：
class ButtonAction
implements ActionListener{
ButtonAction() {}
public void actionPerformed(ActionEvent e){
Object obj = e.getSource();
if (obj == btnAdd){ // Add machine
System.out.println("Should be adding");
//tableData.addText("Test");
tableData.addRow("Test");
}
} // Close if/else block
} // Close actionPerformed
答案 0 :(得分：1)
您将表格模型中的getValueAt指向list，但addText方法正在设置textData中的值。
取消注释动作监听器中的tableData.addText("Test")以及addText将textData.addElement(text)更改为list.add(new MyObject(text))。
