如何在php PHPSReadSheet中使用excel求和公式？

我正在使用phpspreasheet php库。我已经做了几乎所有我想对特定列求和并显示该列总数的事情。。请参见下面我的输出：-

我的预期输出如下所示：-

我尝试了以下代码：-

$spreadsheet = new Spreadsheet();
$Excel_writer = new Xlsx($spreadsheet);
$spreadsheet->setActiveSheetIndex(0);
$activeSheet = $spreadsheet->getActiveSheet();

$activeSheet->setCellValue('A1', 'Location');
$activeSheet->setCellValue('B1', 'Media Vehicle');
$activeSheet->setCellValue('C1', 'Dimension');
$activeSheet->setCellValue('D1', 'Amount');

$spreadsheet->getActiveSheet()->setAutoFilter('A1:D1');
    $locations = DB::table('locations')->get();
    $locations = json_decode(json_encode($locations),true);
    $i = 2;
    foreach($locations as $location){
        $activeSheet->setCellValue('A'.$i , $location['location']);
        $activeSheet->setCellValue('B'.$i , $location['media_vehicle']);
        $activeSheet->setCellValue('C'.$i , $location['dimension']);
        $activeSheet->setCellValue('D'.$i , $location['amount']);
        $i++;
    }

    $samplepath = storage_path('/excels/sampleExcel'.str_random(5).'.xlsx');
    $Excel_writer->save($samplepath);
    echo 'saved'; die;

我要“金额总计”列。我想让它充满活力。如果将来它将是10行，那么它将计算10行amount列计数

您必须取第一名：

第一种解决方案：

 $total = 0;
 foreach($locations as $location){
    $activeSheet->setCellValue('A'.$i , $location['location']);
    $activeSheet->setCellValue('B'.$i , $location['media_vehicle']);
    $activeSheet->setCellValue('C'.$i , $location['dimension']);
    $activeSheet->setCellValue('D'.$i , $location['amount']);
    $total = $total+$location['amount'];
    $i++;
}
//here your $i val already incremented in foreach() loop
$activeSheet->setCellValue('C'.$i , "Total");
$activeSheet->setCellValue('D'.$i , $total);

$activeSheet->setCellValue('C'.$i , "Total");
$spreadsheet->getActiveSheet()->getCell('D'.$i)->getCalculatedValue();

第二种解决方案：

 $total = 0;
 foreach($locations as $location){
    $activeSheet->setCellValue('A'.$i , $location['location']);
    $activeSheet->setCellValue('B'.$i , $location['media_vehicle']);
    $activeSheet->setCellValue('C'.$i , $location['dimension']);
    $activeSheet->setCellValue('D'.$i , $location['amount']);
    $total = $total+$location['amount'];
    $i++;
}
//here your $i val already incremented in foreach() loop
$activeSheet->setCellValue('C'.$i , "Total");
$activeSheet->setCellValue('D'.$i , $total);

$activeSheet->setCellValue('C'.$i , "Total");
$spreadsheet->getActiveSheet()->getCell('D'.$i)->getCalculatedValue();

我提到：

在PHPSReadSheet中，您可以使用Excel公式。 您所需要的只是要求和的数字范围

$SUMRANGE = 'D2:D'.$i;
$activeSheet->setCellValue('D'.$i , '=SUM($SUMRANGE)');

这会有帮助

$i = 2;
$first_i = $i;
foreach($locations as $location){
    $activeSheet->setCellValue('A'.$i , $location['location']);
    $activeSheet->setCellValue('B'.$i , $location['media_vehicle']);
    $activeSheet->setCellValue('C'.$i , $location['dimension']);
    $activeSheet->setCellValue('D'.$i , $location['amount']);
    $i++;
}
$last_i = $i - 1;
$sumrange = 'D' . $first_i . ':D' . $last_i;
$activeSheet->setCellValue('C' . $i, 'Total:');
$activeSheet->setCellValue('D' . $i, '=SUM(' . $sumrange . ')');

我知道这是另一种选择，但我想在此使用excel函数Sum。您可以参考：第二个函数错误调用未定义的方法PhpOffice\phpspreasheet\Worksheet\Worksheet:：getActiveSheet（）。是的，我也尝试过，但总金额列变为空。我们刚刚计算了需要插入值的值
