JTable +排序特定字段 [英] JTable + Sorting specific field
问题描述
我有一个JTable并添加了排序。现在，JTable有5列，第2列在日期字段中转换为DD / MM / YYYY并显示在单元格中的JTextField中。
I have a JTable and have added sorting. Now the JTable has 5 columns and the 2nd column in a date field converted to DD/MM/YYYY and displayed in a JTextField in the cell.
当我对它进行排序时作为字符串和我日期混淆，如何更改该特定列的排序行为？
When I sort it sorts as string and I the dates get mixed up, how do I change the behaviour of sorting for that particular column?
例如。按照ASC顺序排序后，我得到了这个：
eg. after sorting in ASC order, I get this:
01/02/2012
01/03/2011
01/04/2011
01/05/2011
01/06/2011
01/07/2011
01/08/2011
01/09/2011
01/10/2011
01/12/2011
其中是错的，我应该得到的结果如
Which is wrong, and I should be getting the result like
01/03/2011
01/04/2011
01/05/2011
01/06/2011
01/07/2011
01/08/2011
01/09/2011
01/10/2011
01/12/2011
01/02/2012
我的代码现在看起来像这样排序
My code now looks like this for sorting
List<SortKey> sortKeys = new ArrayList<SortKey>();
sortKeys.add(new SortKey(2, SortOrder.ASCENDING));
table.getRowSorter().setSortKeys(sortKeys);
我应该仅针对该特定列更改什么？
What should I change for that specific column only?
推荐答案
您需要实现比较器，将日期字符串视为日期相当简单 String 看看这里
You need to implement comparator that treats date string as Date rather simple String have a look here
