Answer 1

Scenario:
Model PurchaseRequestHeader - underlying database table pr_header has many PurchaseRequestDetail - underlying database table pr_Details
Define both way relationship in the Model classes
class PurchaseRequestHeader extends Model
{
protected $table = 'pr_header';
public function details()
{
return $this->hasMany(PurchaseRequestDetails::class, 'pr_id', 'pr_id');
}
}
class PurchaseRequest Detail extends Model
{
protected $table = 'pr_details';
public function header()
{
return $this->belongsTo(PurchaseRequestHeader::class, 'pr_id', 'pr_id');
}
}
Once relationships are defined, we can retrieve all the PurchaseRequestDetail records related/associated with a record of PurchaseRequestHeader.
$data = PurchaseRequestHeader::with('details')->paginate(25);
$data will have PurchaseRequestHeader(s) with related PurchaseRequestDetails which can be rendered on the view
<tbody>
#foreach($data as $header)
<tr>
<td>{{ $header->pr_id }}</td>
<td>
<table><tbody>
#foreach($header->details as $detail)
<tr>
<td> {{ $detail->field1 }}</td>
<td> {{ $detail->field2 }}</td>
<td> {{ $detail->field3 }}</td>
<td> {{ $detail->field4 }}</td>
</tr>
#endforeach
</tbody></table>
</td>
</tr>
#endforeach
