title: JTable Nimbus Look and Feel - how to make it clear which cell has focus
body: <p>When editing data in a JTable (Nimbus L &amp; F), as the user tabs from cell to cell, it is not obvious which cell has focus. How can I make it clearer which cell has focus? I know there are a number of properties that can be set to modify Nimbus - does anyone know which property I want?</p>
  
  <p>The screen shot below has only one property set to something other than the default:</p>
  
  <pre><code>UIManager.put("Table.showGrid", true);
  </code></pre>
