Question

我检查了有关在JTable上进行水平滚动的stackoverflow的问题。设置AUTO_RESIZE_OFF会使我获得水平滚动条，但同时表格不会使用滚动窗格的整个宽度。

我做了一些阅读，事实证明这是自1998年以来一直在运行bug（Oracle会解决这个问题吗？）

我看到了一些关于骑行方法的建议，但没有一个对我有用。那么有人有答案吗？非常感谢。基本上我需要表自动调整大小，但在任何列名称被压缩之前启用水平滚动条。

感谢。

Answer 1

对其他答案进行咆哮后 - JXTable（在SwingX project中）有一个额外的列布局属性

如果它们的组合pref小于当前宽度，则填充水平视口（即增加列宽），这与autoResizeMode相关
将列大小保持为pref，如果组合的pref大于当前宽度，则显示水平滚动条

需要进行一些内部调整，因此（偏见我）建议使用JXTable。或者看看它的代码和c＆amp; p - 所有允许的，所有开源： - ）

你必须正确设置表格的宽度，更多关于here或here，可运行的例子here

Answer 4

这里有一些链接，我希望它们不会破坏。 swinglabs下载页面在这里：

http://swinglabs.org/downloads.jsp

但是在我访问该网站时，这些下载被破坏了（这可能现在已经解决了），经过一番调查后，我发现他们的服务器上有无聊的访问权限：

http://java.net/downloads/swingx/releases/1.6.2/

这就是我遇到的所有麻烦，只需找到库。这只是将.jar文件解压缩并添加到我的项目然后导入JXTable（org.jdesktop.swingx.JXTable）的问题。

JXTable扩展了常规JTable（参见文档：http://download.java.net/javadesktop/swinglabs/releases/0.8/docs/api/org/jdesktop/swingx/JXTable.html）因此所有常规JTable方法仍然可用。

导入库后，只需告诉表格水平滚动

JXTable table = new JXTable(yourTableModel)
table.setHorizontalScrollEnabled(true)

Swing labs提供了一个可爱的教程，解释了他们在JTable上所做的所有改进。请参阅此处的教程：

希望这有帮助，真的帮助了我。感谢Kleopatra指出了正确的道路。
