Flex DataGrid - Ability to add comments to the cells like MS Excel

Question

I was wondering if there is a way or ready made component in flex for data grid where in a user can punch in comments for any of the grid cell he wants; much similar to what we have in MS Excel 2003/2007/2010. Any thoughts?

SOLUTION :
set in your renderer the border of the component you return to the following
class ATSBorder extends LineBorder {
          public ATSBorder() {
               super(Color.RED);
          public void paintBorder(Component c, Graphics g, int x, int y,
                    int width, int height) {
               g.setColor(lineColor);
               int[] xPoints = new int[]{width - 7, width,width};
               int[] yPoints = new int[]{0,0,7 };
               int nPoints =3;
               g.fillPolygon(xPoints, yPoints, nPoints);
     }
