JTable：如何在运行时选择列
我的表中有太多列，无法一次显示所有列，并且想让用户更改哪些列可见。我该怎么做？
注意：让应用程序在运行时选择列很容易。我要问的是要添加哪些 UI 元素以允许用户在运行时隐藏/取消隐藏列。
I have too many columns in a table to display them all at once, and would like to let the user change which columns are visible. How can I do this?
note: It is easy to make the application select columns at runtime. What I am asking is what UI element(s) to add to allow the user to hide/unhide columns at runtime.

如果您可以导入一些外部库，您可以看看
http://swinglabs.org/docs/components/JXTable/tutorial.jsp 支持此类运行时修改。
If you can import some external libraries, you could have a look to
http://swinglabs.org/docs/components/JXTable/tutorial.jsp which supports such runtime modifications.
表格列管理器允许用户右键单击表标题可控制哪些列可见。
Table Column Manager allows the user to right click on the table header to control which columns are visible.
没有标准方法，但是您可以执行以下操作：
或者：找到一个可以执行此操作的自定义组件。可能已经有一些东西了：像 JIDE 的组件库这样的项目将是一个不错的选择。
There isn't a standard way, however what you could do is something like this:
Alternatively: find a custom component that does this. There probably is something out there already: projects like the component library from JIDE would be a good place to look.
使用 TableModel.addColumn(TableColumn) 和 TableModel.removeColumn(TableColumn) 方法动态显示/隐藏列。
您可以将该调用附加到任何其他 GUI 组件（例如，制作带有几个复选框的 JPanel 或 JTable）。
Use TableModel.addColumn(TableColumn) and TableModel.removeColumn(TableColumn) methods to show/hide columns on-the-fly.
You can attach that calls to any other GUI components (for example, make a JPanel or a JTable with a few checkboxes).
当用户右键单击标题时，显示一个包含可能列的弹出菜单，或者实现一个带有复选框列表的小（轻）弹出对话框，用于选择可见列。可以通过右键单击、单击工具栏按钮或从工具栏菜单打开该对话框。
Either display a popup menu with the possible columns when user right-clicks the header or implement a small (and light) popup dialog with a checkbox list for selecting the visible columns. The dialog can be opened by right-clicking, by clicking a toolbar button or from a toolbar menu.
