使用PHPExcel_RichText添加html

Question

I am using PHPExcel v1.8.0 and am trying to add html tags with PHPExcel.

Since there's no PHPExcel_Helper_HTML class available with this version, I need to guess I've to rely on PHPExcel_RichText.

What's the PHPExcel_RichText equivalence to the following:

$html = '<ul>';
foreach ($someArr as $key => $value) {
   $html .= '<li>'.$value.'</li>';
}
$html .= '</ul>';

$objPHPExcel->getActiveSheet()->setCellValue('I'.$rowID, $this->richText($html));
