  <p>I would like to get the Create Shopping Cart picture and the associated text to be aligned center in their respective cells in the panel. For details - the shopping cart picture would have to be in the center of the gray cell of the panel. And the text in the JTextArea have to be center aligned as well. Can you please help. My code is attached.</p>
