title: Java Swing - Multiple column headers in a JTable?
body: <p>Is there any way to create multiple column headers in a <code>JTable</code>? I mean, normally there is only one row, but I need two of them with the same format (headerlike), and combine some cells of one of those headers.</p>
  
  <p>I need something like this:</p>
  
  <pre>
  Header0 |          Header123          | Header4
  Header0 | Header1 | Header2 | Header3 | Header4
  </pre>
  
  <p>Is there any way?</p>
