Hi good friends. I'm having trouble with my Jtable. I have a table that has two columns, file and date modified. The date format needs to be SimpleDateFormat("MM-dd-yyyy-HH:mm:ss")
These columns need to be sortable. I have no problem sorting on the file name side. Unfortunately, the date side won't auto sort correctly. (Most notable when the years are not the same).
I normally would just sort by the lastModifed value, but I can't find a way to have both correct sorting AND the little up and down arrows that tell you which direction you've been sorting. I can get one OR the other.
I want to
1) Have the arrows.
2) When clicking on the date column i want correct sorting.
3) The date needs to be displayed in the SimpleDateFormat("MM-dd-yyyy-HH:mm:ss")
If I remove the sortKeys.add(new RowSorter.SortKey(1, SortOrder.ASCENDING));,
I add my own custom sort to the data before i add it to the table, but no arrows.
If I add that line, then I get my arrows, but i can't get correct sorting.
Then you need to use a custom renderer to format the Date.See Table Format Renderers for a simple class you can use to do this.

Thanks. When I sorted on date, I still ran into issues. I ended up still using the formatter, but I initially set the column to be lastModified. Then I did the converstion to date before i formatted. Thanks for the help!
