title: How to style title in exported pdf in datatable
body: <p>The code in question:</p>
  
  <pre><code>$("#my-table").DataTable( {
              data: dataSet,
              columns: columns,
              dom: 'Bfrtip',
              buttons: [
                  {
                      extend: 'excelHtml5',
                      title: 'Awesome Export',
                  },
                  {
                      extend: 'pdfHtml5',
                      title: 'Awesome Export',
                      orientation: 'landscape',
                      pageSize: 'LEGAL'
                  }
              ]
          });
  </code></pre>
  
  <p>How can I style the title using maybe html:</p>
  
  <pre><code>var title = '&lt;h1&gt;My title&lt;/h1&gt;&lt;br /&gt; &lt;p&gt;by John&lt;/p&gt;';
  
  // then in the code
  ...
  buttons: [
      {
          extend: 'excelHtml5',
          title: title
      }
  ]
  ...
  </code></pre>
  
  <p>If I try to do this it displays the html tags instead of styling it.</p>
