title: Change background color of every other row
body: <p>I'm trying to replicate the default settings of <code>ag-grid</code> which paints every other rows background in a slightly different color. But when I try to reorder columns clicking on <code>headerColumn</code> the background colors doesn't reorder.</p>
  
  <p>This is my current approach that isn´t working</p>
  
  <pre class="lang-js prettyprint-override"><code>cellStyle(params) {
    let backgroundColor = #FFFFFF;
    if (params.node.rowIndex % 2 === 1) backgroundColor = #E04F00;
  }
  </code></pre>
  
  <p><a href="https://plnkr.co/edit/bHLEmECLNby3obIT" rel="nofollow noreferrer">https://plnkr.co/edit/bHLEmECLNby3obIT</a>, this example shows the desired behavior.</p>
  
  <p>Is there a way to acces and change those default colors?</p>
