title: Change the background color of a row in a JTable
body: <p>I have a JTable with 3 columns. I've set the <code>TableCellRenderer</code> for all the 3 columns like this (maybe not very effective?).</p>
  
  <pre><code> for (int i = 0; i &lt; 3; i++) {
       myJTable.getColumnModel().getColumn(i).setCellRenderer(renderer);
   }
  </code></pre>
  
  <p>The <code>getTableCellRendererComponent()</code> returns a Component with a random background color for each row.<br>
  How could I change the background to an other random color while the program is running?</p>
