<table>
    <thead>
        <tr>
            <th>S.No</th>
            <th> Name</th>
            // this foreach for <thead> to print the subject names
                @foreach($subject_list->unique('subject_id') as $list)
                <th>{{ $list->subject_name }}</th>
                @endforeach
                <th>Total</th>
                <th>%</th>
        </tr>
    </thead>

    <tbody>
        @foreach ($students as $index=>$student)
        // this main loop brings the first student inside
        @foreach($student->studentexamsubjectwisemark as $printmark)
        // this inner loop brings first student 5 subject marks
        @endforeach
        <tr>
            <td> {{ $student->name_of_the_studeent }} </td>
            <td> {{ $student->his_first_subject_mark }} </td>
            <td> {{ $student->his_second_subject_mark }} </td>
            <td> {{ $student->his_third_subject_mark }} </td>
            <td> {{ $student->his_fourth_subject_mark }} </td>
            <td> {{ $student->his_fifth_subject_mark }} </td>
            </td>
            @endforeach
    <tbody>
</table>

actually i need to print each student name and marks. here the subjects are dynamic based on subject selected the report is generated. it may 2 subjects, 2 or 4 and so on. thats why i put a foreach in thead also

in tbody the first foeach first student will come he may wrote only 2 exams remaining 3 exams he may be absent. so my doubt is

1. if i print the marks after the innerforeach iam unable to print . if i print the marks with student name within the innerforeach the it will be correct but student name will be printed as much as subject count. so how i need to print the student mark as innerforeach contain the suject.

2)if student absent means there will be no record then how i shud compare and print 0 if student not has record.

Kindly some one help please.
