错误的文本格式phpExcel

Question

我正在创建一个php脚本，用于查询远程SQL数据库并通过PHPExcel在excel上导出结果。 在我的数据库中，我有一列名为“syllabus”的varchars，其值为。 如果我在HTML上创建一个简单的表格，文本是正确的 但是，如果我导出到excel，则返回给我： 该列被格式化为文本，如果我手动插入数据，它的工作没有问题。 这是脚本：`errno）die（$ mysqli-＆gt; error）;

require_once '/home/ecdlmalignani/ecdl.malignani.org/Classes/PHPExcel.php';

$phpExcel = new PHPExcel;

// Load an existing spreadsheet
$phpExcel = PHPExcel_IOFactory::load('/home/ecdlmalignani/ecdl.malignani.org/template.xlsx');

if(isset($_GET['sessione']))
{
    $sql  = "SELECT skill_card.`ID_skillCard`, utenti.cognome, utenti.nome, DATE_FORMAT(utenti.data_nascita, '%d/%m/%Y') AS date, moduli.descrizione_modulo, moduli.syllabus\n"
            . "FROM `skill_card` INNER JOIN utenti ON skill_card.`cod_fiscale` = utenti.cod_fiscale\n"
            . "INNER JOIN esami ON esami.skill_card = skill_card.`ID_skillCard`\n"
            . "INNER JOIN moduli ON moduli.ID_modulo = esami.ID_modulo\n"
            . "WHERE esami.ID_sessione=".$_GET['sessione']." AND esami.pagato = 'SI' AND esami.stato = 'ISCRITTO'";
    $res = $mysqli->query($sql);
    $row_increment = 0;
    while ($row = $res->fetch_array(MYSQLI_BOTH))
    {
        for($column_increment = 0; $column_increment < 5; $column_increment++)
        {
            $cell = chr(65+$column_increment) . chr(50+$row_increment);
            $phpExcel->getActiveSheet()->setCellValue($cell, $row[$column_increment]);
        }
        $phpExcel->getActiveSheet()->setCellValue('F'.chr(50+$row_increment), $row['syllabus']);
        $phpExcel->getActiveSheet()->setCellValue('G'.chr(50+$row_increment),'it');
        $phpExcel->getActiveSheet()->setCellValue('H'.chr(50+$row_increment),'ATLAS');
        $row_increment++;
    }
