Ok, heres the situation. I have a Jtable with 7 columns and many rows. I want to be able to sort the columns when the header is clicked on. I've search on Google and the API for anything like this, but found nothing of good use.
Does anyone have an idea on how to do this?

Also in the JTable, I want to be able to double click on a row and it opens that file corresponding to the row. The columns basically have info about the file. Again, I searched and nothing. Any ideas?
