【问题描述】：
我有一个数据，我想根据他们的学年和学期按组打印。在 MS Access 中，我可以使用关系和组报告来做到这一点。我在 Laravel 中做，但我遇到了困难。
这里是示例记录
| SUBJECT CODE | DESCRIPTIVE TITLE | UNITS | GRADE | CREDIT | SY | SEM |
|---|---|---|---|---|---|---|
| BMATH 01 | BUSINESS MATHEMATICS | 3 | 2.25 | 3 | 2017-2018 | 1st |
| BMATH 02 | MATH OF INVESTMENT | 3 | 2.00 | 3 | 2017-2018 | 2nd |
| BUSCOR | BUSINESS ENGLISH CORRESPONDENCE | 3 | 2.00 | 3 | 2018-2019 | 1st |
| ECO 01 | INTRO TO ECONOMICS WITH LAND REFORM AND TAXATION | 3 | 1.75 | 3 | 2017-2018 | 1st |
| ECO 02 | MICROECONOMICS THEORY AND PRACTICE | 3 | 1.75 | 3 | 2017-2018 | 2nd |
| ELEC 01 | PROJECT DEVELOPMENT MANAGEMENT | 3 | 1.50 | 3 | 2018-2019 | 1st |
| ELEC 09 | BUSINESS ETHICS | 3 | 2.75 | 3 | 2019-2020 | 1st |
| ELEC B | FRANCHISING | 3 | 2.00 | 3 | 2019-2020 | 1st |
| ELEC BA 3 | COOPERATIVE MANAGEMENT | 3 | 1.50 | 3 | 2018-2019 | 2nd |
| ELEC BA 5 | FEASIBILITY STUDY | 3 | 1.75 | 3 | 2018-2019 | 2nd |
| ELEC BA 6 | RISK MANAGEMENT | 3 | 2.50 | 3 | 2019-2020 | 1st |
我想像这样打印和分组它们
| SUBJECT CODE | DESCRIPTIVE TITLE | GRADE | CREDIT |
|---|---|---|---|
| ----------------------------- | 2017-2018 |
1st |
----------------------------- |
| BMATH 01 | BUSINESS MATHEMATICS | 2.25 | 3 |
| ECO 01 | INTRO TO ECONOMICS WITH LAND REFORM AND TAXATION |
1.75 | 3 |
| ----------------------------- | 2017-2018 |
2nd |
----------------------------- |
| BMATH 02 | MATH OF INVESTMENT | 2.00 | 3 |
| ECO 02 | MICROECONOMICS THEORY AND PRACTICE |
1.75 | 3 |
等等等等。
Laravel 可以输出这个打印报告吗？
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]);
}
这是我的刀片文件

Laravel 是否有其他方法或功能可以使这成为可能。 非常感谢。。
