如何防止单个列在JTable中重新排序？ [英] How to keep a single column from being reordered in a JTable?

问题描述

我有一个 JTable ，我需要能够重新排序列。但是我希望第一列无法重新排序。我使用以下命令启用重新排序：

I have a JTable and I need to be able to reorder the columns. However I want the first column to not be able to be re-ordered. I used the following to enable reordering:

table.getTableHeader().setReorderingAllowed(true);

现在可以重新排序列，包括我不想要的第一列。有没有办法锁定第一列？

The columns can now be reordered including the first column which I don't want. Is there any way to lock the first column?

我见过一些使用两个表的解决方案，第一列在一个单独的表中，但也许有更好/更简单的方法。

I have seen some solutions that use two tables with the first column being in a separate table, but maybe there's a better/simpler way.

推荐答案

我认为您需要覆盖中的 columnMoved（）方法TableColumnModelListener 。 TableColumnModelEvent 类有一个 getFromIndex（）方法，您应该能够查看它以确定它是否是您的固定列，然后你应该能够取消该事件。

I think that you need to override the columnMoved() method in TableColumnModelListener. the TableColumnModelEvent class has a getFromIndex() method that you should be able to look at to determine if it's your fixed column, and then you should be able to cancel the event.
