【问题描述】：

好的，我正在创建一个选举网站 我有一个表格从每个部分获取候选人的票数，我的问题是我得到了多个具有相同候选人名称的列，我需要将具有相同标题的所有列合并到 1 列中，并且投票将是彼此下方。 表格图片：

表格代码index.blade.php：

    <table class="table table-sm table-hover table-dark text-center">
        <thead class="text-center" style="font-weight:bolder;color:green">
            <tr>
                <td style="padding: 20px;">اضافه مرشح</td>
                <td style="padding: 20px;">اسم مرشح</td>
                <td style="padding: 20px;">Action</td> 
    <?php
                    
                     $counter = App\Models\Morshah::select('name')->where('dayra','=>','5')->groupBy('name')->get()->count();  
    
                    
                    ?>

        $datas = AfterDay::orderBy('id','asc')->where(['dayra'=>'5'])->get();
        $morshah = Morshah::orderBy('id','asc')->where(['dayra'=>'5'])->get();

【问题讨论】：

欢迎来到SO，我们实际上不明白这里的标题是什么，非英语的原因。无论如何，您不能将多行合二为一，但您可以忽略循环中的重复行

@sta 3 列的三个箭头标题是测试名称（确切地说是相同的名称），我希望将 3 列合并为 1 列，下面的数字（投票）是都在彼此之下

根据您的查询分组，它会在收集的同时轻松组合您的数据$datas = AfterDay::orderBy('id','asc')->where(['dayra'=>'5'])->groupBy('name')->get();

【参考方案1】：

不能随意组合，但可以用array_unique()忽略重复数据：

foreach (array_unique($data) as $datas) 
   // Do stuff with $d ...
