页眉/页脚和分页未使用mPDF和PHPExcel导出？

Question

I use mPDF with PHPExcel and it seems like headers and footers are not exported from my excel content. Is there a way around that?

If not, can I re-create/add the headers and footers right before the PDF is created?

If not, is there a way to just add page numbers to the pdf?

Thanks!

Edit // More code. See the Header/Footer part:

PHPExcel_Settings::setZipClass(PHPExcel_Settings::PCLZIP);

$objReader = PHPExcel_IOFactory::createReader("Excel2007");
$objReader->setIncludeCharts(TRUE);
$objPHPExcel = $objReader->load("excel.xlsx");

$rendererName = PHPExcel_Settings::PDF_RENDERER_MPDF;
$rendererLibraryPath = dirname(__FILE__) . '/mpdf';

$objWorksheet = $objPHPExcel->getActiveSheet();

// Header and Footer
$title = "Title";
$sub_title = "Subtitle";
$sub_title = "Title";
$date_exported = date('Y-m-d H:i');

$objWorksheet
    ->getHeaderFooter()->setOddHeader('&L&14'.$title."
&11".$sub_title."&R&10Exported with PHP
" . $date_exported);
$objWorksheet
    ->getHeaderFooter()->setEvenHeader('&L&14'.$title."
&11".$sub_title."&R&10Exported with PHP
" . $date_exported);
$objWorksheet
    ->getHeaderFooter()->setOddFooter("&RPage &P of &N");
$objWorksheet
    ->getHeaderFooter()->setEvenFooter("&RPage &P of &N");
