Creating Overlay Icons - Table Viewer

Sometimes in table viewer icon decoration is not possible. We can create overlay icons and return them in class ITableLabelProvider method's - public Image getColumnImage(Object element, int columnIndex) will be enough

 ImageDescriptor desc = Activator.getImageDescriptor(....); // It take String (Image Path)  
 if (desc != null) {  
      DecorationOverlayIcon decoratedImage = new DecorationOverlayIcon(image,   
                desc, IDecoration.BOTTOM_LEFT);  
      if (decoratedImage != null) {  
           return decoratedImage.createImage();  
      }  
 }
