Загрузить данные Excel на webiste через phpspreadsheet

Question

С помощью PHPSpreadreader я хочу загрузить файл Excel на свой веб-сайт (в таблицу HTML). Инструкции: https://phppot.com/php/import-excel-file-into-mysql-database-using-php/

Пока все работает, но когда я хочу загрузить файл Excel, содержащий более 10 столбцов, код больше не работает. Я изменил код соответствующим образом (от 0 до 11 строк).

У кого-нибудь есть идеи, что может быть причиной?
