title: How do I center the entire DataTable in the pdf using JQuery pdfHtml5
body: <p>I'm loving using <code>$('#tableId').DataTable()</code> and the "pdfHtml5" button to generate a PDF. I just can't figure out how to center the information within the generated PDF. </p>
  
  <p>A Table with only two columns shows up on the left of the .pdf, but would look much better if it were just centered.</p>
  
  <p>I am pretty sure it's supposed to be done in the button, but have not quite figured out the last bit.</p>
  
  <p>Current Example (not quite working):</p>
  
  <pre><code>extend:"pdfHtml5",
  className: "btn",
  text: "Export To PDF",
  title: "PDF Title",
  filename: "AFileName",
  messageTop: "Test Message",
  
  // And this is where I think I'm close...
  customize: function(doc) {
      // doc ? = ?
  }
  </code></pre>
  
  <p>Any thoughts?</p>
