Adding an Icon to JTable by overriding DefaultTableCellRenderer

Question

I\'m trying to add an icon to a particular JTable column by specifying my own table cell renderer as below (based on parts of this tutorial):

public class My         


        

Answer 1

For better performance reasons JTable reuses the same label for each cell it renders. This means you need to set both text and icon each time you change it.

The same goes for fonts, backgroundcolors and the like

 if(icon == null){
                    label.setText(status);
                    label.setIcon(null);
            }else{  
                    label.setText("");
                    label.setIcon(icon);
            }

should do the trick,
