我在JScrollPane中有JTable，但是我正在为这个问题苦苦挣扎，水平滚动时JTable不适合JScrollPane。我在JTable中有18行，但是水平滚动时只显示16行。这是我的意思
<<因此，从图片中可以看到，行在列上运行，而最后两行丢失。
我还没有进行任何编程编码，所有操作都已使用Netbeans IDE Design构建器完成。
P.S。您有意思的事实是，如果我展开程序或进入全屏显示，则程序会显示所有必须存在的列。但是，如果我再次缩小程序并尝试使用水平滚动，则会发生这种情况。
[如果我错过了任何事情（很抱歉第一次在这里发布），请问。感谢您的帮助！
这是来自Netbeans的有关主UI窗口的代码
