JTable: Store different data than displaying

i have a question about the JTable in Java. Im reading Time-String from a database in the international standard-format (year:month:day Hours:Minutes). Thats cool beacause of sorting my table by time.

BUT the client wants to display the time in the format day:month:year Hours:Minutes). Its no problem to display it this way, but easy sorting is not possible anymore.

Im searching for a solution to store the original data for sorting and display the new format. I know in Flex there is such a thing like data und label for a cell.

Is there anything similar in Java?

Thank you very much!!

Generally date information should not be stored as a String for the reason you just gave. Different application want to format the data differently. So the data should be stored as a Date object in the model. Then you use a renderer to format the date anyway you wish.

Table Format Renderers shows you an easy way to do the formatting.

You can use a custom cell renderer to change how the value is displayed while keeping it in store with a sortable format:
