Accessing a JTextField in JTableHeader

I have tryed to make a array of JTextfield that will set on the header, so i can access them on code base. Unlucky that didnt workout, i was wondering if its possible to get access to this JTextField in the header and what is the best way to do this. Tableheader renderer: public class
