title: Full table background color in swing
body: <p>I'm building my Java application interface using a lot of Photoshop.
  But after implementing a table it doesn't look pretty cool as you can see:</p>

  <p>I would like to make the table as transparent as possible, so only letters are shown. I have setted all the colors to black.
  Any solution?</p>
