Question

我正在用PHPspreadshet生成一个xlsx文件，当它具有16行以上时，它总是给我一个空文件（0kb）。我已经尝试搜索错误等，但一无所获。它仅取决于行。电子表格（用于测试的HTML）：

当我切换以下行时：

 $this->sheet->setCellValue("A16", "Besetzt");

收件人

 $this->sheet->setCellValue("A17", "Besetzt");

生成器（execute（）是入口点）：

class ExcelOperation extends AbstractOperation

    private function addWork($cell, $name = "", $phone = ""){
        if($cell != null){
            $richText = new \PhpOffice\PhpSpreadsheet\RichText\RichText();

            $boldText = $richText->createText($name);
            //$boldText->getFont()->setBold(true);
            $richText->createText("\n".$phone);
            $this->sheet->getCell($cell)->setValue($richText);
            $this->sheet->getStyle($cell)->getAlignment()->setWrapText(true);

        $this->colors = [
            "black"=>\PhpOffice\PhpSpreadsheet\Style\Color::COLOR_BLACK

   }

}

它将生成一个空文件。

如果PHPSpreadsheet包含超过16行，则会生成空文件
