java - 在两列中过滤 JTable

Question

我想在我的 JTable 中实现 2 个不同的行过滤器。我已经实现了一个似乎完美无缺的工作，但我的第二个似乎没有工作。在下面的代码中，我注释掉了一些数据部分并放入了示例数据，这样它就可以在没有其他文件的情况下工作。

谁能告诉我问题出在哪里并告诉我如何解决？此外，如果有人在 filterAthID 中搜索了某些内容，然后开始在 filterForeName 中键入内容，这是否可行？通过工作，我的意思是通过输入的数据进一步过滤剩余的结果。如果没有，有没有办法结束这个？如果有办法克服这个问题，您能解释一下吗？

Answer 1

In the following code I have commented out a few parts of data and put in sample data so it works without other files.

不要只是注释掉代码，将它从我们不感兴趣的帖子中删除。

另外，为什么要包含按钮的所有代码？这些按钮与问题无关，因此我们不想通读所有代码。阅读的代码越少，我们就越有可能找到问题。

however my second one does not appear to work.

在我看来你有错字:

//rf = RowFilter.regexFilter(filterAthID.getText(), 1);

您应该使用过滤器的名称(而不是 ID):

rf = RowFilter.regexFilter(filterForeName.getText(), 1);

编辑:

同时过滤两列的例子:

List<RowFilter<Object,Object>> filters = new ArrayList<RowFilter<Object,Object>>(2);
filters.add(RowFilter.regexFilter(textField1.getText(), 0));
filters.add(RowFilter.regexFilter(textField2.getText(), 1));
rf = RowFilter.andFilter(filters);
