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是我的第二个似乎不起作用。在下面的代码中，我已经注释掉了一些数据部分并放入了示例数据，因此它可以在没有其他文件的情况下工作。

有人可以告诉我问题是什么，并告诉我如何解决它？一旦这个工作，如果有人在filterAthID中搜索了一些东西然后开始在filterForeName中键入一些东西它会起作用吗？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，那么反过来呢？如果有一种方法可以解决这个问题，请解释一下吗？
答案 0 :(得分：3)
在下面的代码中，我已经注释掉了一些数据部分并放入了样本数据，因此它可以在没有其他文件的情况下工作。
不要只是注释掉代码，将其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？按钮与问题无关，因此我们不想阅读所有代码。读取的代码越少，我们就越有可能找到问题。
然而我的第二个似乎不起作用。
在我看来你有一个错字：
//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：
同时在两列上过滤的示例：
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);
