I'm making a spreadsheet program in java but i am stuck on getting my mouselisteners to behave the way i want them to.

On mousePressed the clicked on cell in the array defaulttablecellrenderer should change colour, like in excel or any spreadsheet program. but i've tried numerous methods but still can't get it to work. Here is my code for the mouselistener part:

(Toggle Plain Text)

				
public void mousePressed(MouseEvent e) {
					// TODO Auto-generated method stub
						for (int i = 0; i<cell.length;i++){
						if (cell[i] == e.getSource()){
							cell[i].setBackground(Color.BLUE);
							System.out.println("worked");
						}
						else{
							System.out.println("no");
						}
					}


				}

The system does print out "worked" so i guess my listeners are working, but i just can't seem to get the background of that cell clicked upon to change.
Maybe i am overlooking something very simple or maybe not.
Any ideas?
