title: jQuery DataTables export pdf cuts off columns
body: <p>I have a dataset with large number of colums.</p>
  
  <p>When exporting the pdf , columns that dont fit on the page get cut off.</p>
  
  <p>I tried using the 'orientation' and 'page-size' options but its not enough.</p>
  
  <pre><code>    buttons: [
                  {
                      extend: 'pdfHtml5',
                      orientation: 'landscape',
                      pageSize: 'LEGAL'
                  }
              ]
  </code></pre>
  
  <p>Ideally it should do one of the following:</p>
  
  <ol>
  <li>Fit the data on one page ( making the font really small )</li>
  <li>Continue the data in another page in the the pdf</li>
  </ol>
