JTable之间的差距很大
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）。
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); } class ResultsPanel extends JPanel implements ActionListener { private ArrayList venueList;

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。 还删除了setPreferredSize，但结果仍然相同。

仅供参考，“抽奖”中的空白点无关紧要。
没有一个完整的例子，很难确定你所看到的。 鉴于应该避免使用setPreferredSize() ，请注意JTable实现了Scrollable并且可以计算它自己的首选大小。 不幸的是，计算的任意Dimension可能导致问题。 例如，重写getPreferredScrollableViewportSize()以返回getRowHeight()的倍数可能是一个有用的替代方法。
