Normally in excel you can give a specific name to the cells. How can this be done in phpexcel?
Section 4.6.38 of the Developer documentation describes how to do this: the section entitled "Define a named range"
$objPHPExcel->addNamedRange( new PHPExcel_NamedRange('PersonFN', $objPHPExcel->getActiveSheet(), 'B1') );
