如何在php phpspreadsheet中使用excel总和公式？

Question

我正在使用 PhpSpreasdheet php 库。 我已经完成了几乎所有我想要对特定列求和并想要显示该列的总数的所有事情。请参阅我的输出如下：-

我的预期输出如下：-

我试过下面的代码：-

$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;

我想要总金额列。 我想要动态。 如果将来它将是 10 行，那么它将计算 10 行的金额列数。

Answer 1

在 phpspreadsheet 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)');

Answer 2

你必须总共拿 1 次：

第一个解决方案：

 $total = 0;
 foreach($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);

第二种解决方案：

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

Answer 3

我会帮你的;

$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 . ')');
