title: Tabulator (getData() on custom property sent in JSON like last_page?)
body: <p>getData() on custom property sent in JSON like last_page?</p>
  
  <p>Is there a way to get at a custom property from the table object? I was thinking of sending in a property like last_page at the top level of the JSON that would hold the total record count. This would be handy for remote pagination information in the footerElement:. Can't really do the math with out the exact total.</p>
  
  <p>e.g. Showing 1 to 10 of 13 rows</p>
  
  <p>The 13 is an unknown with remote. I would like to send it in and d a getData("total_records") or something without having to add to every row object.</p>
