如何在php phpspreadsheet中使用excel sum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内容。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。我想让动态。如果将来它将是 10 行，那么它将计算 10 行的数量列数。

Answer 1

会有帮助的；

$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 . ')');

Answer 2

在 phpspreadsheet 中，您可以使用 Excel 公式。 您只需要求和的数字范围即可。

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

Answer 3

你必须拿总第一：

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);

第二个解决方案：

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