These are really two quite separate questions

a. you need to sort the TableModel
b. you need to set the cell renderer appropriately

a. Something like

class SortableDefaultTableModel extends DefaultTableModel implements Comparator {

      private int sortColumn;

      public void sortByColumn(int sortColumn){
            this.sortColumn = sortColumn;
            //System.out.println("Sorting on column " + sortColumn);
            Collections.sort(dataVector, this);
      }

      public int compare(Object o1, Object o2){
            if (o1 == null) return -1;
            if (o2 == null) return 1;

            Vector vect1 = (Vector) o1;
            Vector vect2 = (Vector) o2;
            Comparable col1 = (Comparable) vect1.get(sortColumn);
            Comparable col2 = (Comparable) vect2.get(sortColumn);
            return col1.compareTo(col2);
      }
}
