I tried your example and got an error:
Fatal error: Uncaught exception 'Exception' with message 'Cell coordinate string can not be a range of cells.' in /var/www/excel/Classes/PHPExcel/Worksheet.php:1085 Stack trace: #0 /var/www/excel/Tests/functions.php(261): PHPExcel_Worksheet->getStyle('A1:P14') #1 {main} thrown in /var/www/excel/Classes/PHPExcel/Worksheet.php on line 1085
in the example I found the following bug:
$ aFont = array ( 'name' => 'Wingdings'. $suffix,' size '=> 18);
should be replaced by the
$ aFont = array ( 'name' => 'Wingdings '. $suffix,' size '=> 18);
between the Windings and $suffix must be a gap
Help me plz
