将JTable添加到JScrollPane

我一直在制作一个包含JTable的小应用程序。问题是这样的：当我将JTable添加到JScrollPane时，它给我提供了一个错误，即表组件不止一次地添加到父组件。将JTable添加到JScrollPane

getContentPane().add(new JScrollPane(table)); 
scrollPane.setViewportView(table);

我看到问题，但无法解决它。有什么建议么？

'我看到的问题，但解决不了它。 ' - 你是什么意思，你不能解决它？摆脱这些陈述之一？我们不能告诉你该怎么做，因为我们不知道你的要求是什么。 – camickr

谢谢，是的，我确实拿出了其中一个陈述，但是当我拿出时，桌子没有显示。 – Latif

错误是正确的：“滚动客户端（也称为数据模型）由JViewport视图中显示”一个JScrollPane只能有一个如果您的“不是直接向JScrollPane构造函数提供视图，则只需要setViewportView()”。

JTable table = new JTable(data, col); 
add(new JScrollPane(table));

另外，不要用这种方式使用setBounds()。相反，覆盖Scrollable接口方法getPreferredScrollableViewportSize()和pack()的封闭窗口，如图所示here。

JTable table = new JTable(model) { 

    @Override 
    public Dimension getPreferredScrollableViewportSize() { 
     return new Dimension(1024, 512); 
    } 
}; 
add(new JScrollPane(table)); 
pack();

谢谢，我尝试了你展示的方式，但是这次表格没有显示。 – Latif

@Laddie：您可能会验证[示例]（http://stackoverflow.com/a/13919878/230513）的作用，然后将其与您的代码进行比较。确保'setVisible（）'_follows_构造。如果不这样做，请编辑您的问题以包含一个展示问题的[完整示例]（http://stackoverflow.com/help/mcve）。 – trashgod

好吧，我会发送完整的示例 – Latif

JTable table = new JTable(); 
JScrollPane scrollPane = new JScrollPane(table); 
JFrame frame = new JFrame(); 
frame.add(scrollPane);

应该很好地工作。
