问题描述
以下是提供我正在寻找的结果的方法，但不幸的是，当显示每页的表格之间存在很大差距。这样我每个标签只能在屏幕上放入其中两个（每个表只有两行）。
The below is on the way to providing the results I am looking for, but unfortunately when this displays there is a large gap between tables on each page. It is so that I can only fit two of them on the screen per tab (with just two rows per table).
private void display() {
JFrame f = new JFrame("Test");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(new JLabel("Test"));
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}

我如何解决这个问题？谢谢
How would I go about fixing this? Thanks
编辑：编辑为每个请求添加完整代码...大部分内容与此处发生的事情无关。同样删除了setPreferredSize，但结果仍然相同。
Edited to add full code per request... most of it is irrelevant to what is going on here. Also removed setPreferredSize, but still same result.

仅供参考，抽奖中的空白点无关。 / p>
FYI, the blank spot in "Draws" is unrelated.
推荐答案
如果没有完整的例子，很难确定你所看到的是什么。鉴于应该避免 setPreferredSize（） ，请注意 JTable 实现可滚动并可以计算它自己的首选大小。不幸的是，计算出的任意 Dimension 可能会导致问题。覆盖 getPreferredScrollableViewportSize（）为 getRowHeight（）的倍数.com / a / 14429388/230513>示例，可能是一个有用的替代方案。
Absent a complete example, it's hard to be sure what you're seeing. Given that one should avoid setPreferredSize(), note that JTable implements Scrollable and can calculate it's own preferred size. Unfortunately, the arbitrary Dimension calculated may be causing the problem. Overriding getPreferredScrollableViewportSize() to return a multiple of getRowHeight(), for example, may be a useful alternative.
