laravel是否可以输出此打印报告？
这是我的控制器：

public function viewTOR($id){

        $student = Student::where('stud_no', $id)->first();

        $grades = DB::table('grades')
        ->distinct()
        ->leftJoin('subjects', function($join)
            {
                $join->on('subjects.subj_code', '=', 'grades.subj_code');

             })
        ->where('grades.student_number', '=', $id)

        ->get();

        //echo "<pre>"; print_r($unitsSum);die;
       return view('admin.grades.viewtor', ['grades'=>$grades,'student'=>$student]);

    }

这是我的刀锉

laravel是否有其他方法或功能可以实现这一点。非常感谢你。。

我就是这样做的：

$grades = $grades->groupBy(function($grade) {
  return $grade->sy.' '.$grade->sem;
})->sortKeys();

<table class="table">
    <thead>
        <tr>
            <th>SUBJECT CODE</th>
            <th>DESCRIPTIVE TITLE</th>
            <th>GRADE</th>
            <th>CREDIT</th>
        </tr>
    </thead>
    <tbody>
        @foreach($grades as $sysem => $semgrades)
            <tr><th colspan="4" style="text-align:center;">{{ $sysem }}</th></tr>
            @foreach($semgrades as $grade)
                <tr>
                    <td>{{ $grade->subj_code }}</td>
                    <td>{{ $grade->descriptive_title }}</td>
                    <td>{{ $grade->subj_desc }}</td>
                    <td>{{ $grade->list1 }}</td>
                </tr>
            @endforeach
        @endforeach
    </tbody>
</table>
