Question

当我用一些工作表（“逆变器n°”）创建我的文件时，我发现了一个空的“工作表”表。如何消除它？

我的代码：

for ($i = 1; $i <= 4; ++$i) { // to create 4 files
    $objPHPExcel = new PHPExcel();
    for ($n = 1; $n <= 10; ++$n) { // to create 10 sheets for each files

        $objPHPExcel -> createSheet();
        $objPHPExcel -> setActiveSheetIndex($n);
        $objPHPExcel -> getActiveSheet() -> setTitle('Inverter '.$n);
        $objPHPExcel -> getActiveSheet() -> fromArray($impianti[$i]["inverter".$n]);

    }
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    $objWriter -> save($output.".xlsx");        
}

初始化对象时，PHPExcel会创建一个新工作表。只需在创建工作表之前添加if语句:)

编辑：索引从零开始，因此调整以反映此

for ($i = 1; $i <= 4; ++$i) { // to create 4 files
    $objPHPExcel = new PHPExcel();
    for ($n = 0; $n < 10; ++$n) { // to create 10 sheets for each files

        if ($n > 0) $objPHPExcel->createSheet();
        $objPHPExcel->setActiveSheetIndex($n);
        $objPHPExcel->getActiveSheet()->setTitle('Inverter '.($n+1));
        $objPHPExcel->getActiveSheet()->fromArray($impianti[$i]["inverter".($n+1)]);

    }
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    $objWriter->save($output.".xlsx");        
}

PHPExcel：不要求工作表
