你可以簡單的做到這一點的看法：

<?php $cumulative = 0; ?> 

@foreach ($collection as $object) 
    <?php $cumulative += $object->value; ?> 
    {{ $object->value }} | {{ $cumulative }} 
@endforeach

創建功能，並按照與

public function CumulativeCalculator($accounts){ 

    $driverAccounts  = []; 
    $cumulativePayments = 0; 
    foreach($accounts as $account){ 

     $cumulativePayments += $account->value; 
     $currentDriverAccounts = []; 
     $currentDriverAccounts['id'] = $account->id; 
     $currentDriverAccounts['realValue'] = $account->value; 
     $currentDriverAccounts['cumulativeValue'] = $cumulativePayments; 
     array_push($driverAccounts,$currentDriverAccounts); 
    } 
    return $driverAccounts; 

} 

在你的視圖中這樣做

<table class="table table-hover table-striped"> 
<thead> 
    <th>Values</th> 
    <th>Cumulative Values</th> 
</thead> 
<tbody> 
    @foreach($driverAccounts as $dataValue) 
     <tr> 
      <td>{{$dataValue['realValue']}}</td> 
      <td>{{$dataValue['cumulativeValue']}}</td> 
     </tr> 
    @endforeach 
</tbody> 

這將爲你工作，對不起我在匆忙但它會奏效。
