title: Change color of row programmatically in WatchKit
body: <p>I'd like to change the color of a row in a WKInterfaceTable if it has been selected. I've done these steps but don't know how I can go further:</p>
  
  <pre><code>override func table(table: WKInterfaceTable, didSelectRowAtIndex rowIndex: Int) {
  
      let row = tableView.rowControllerAtIndex(rowIndex) as! TableRowObject
  
  }
  </code></pre>
  
  <p>I hope someone of you guys can help me to do this. </p>
