Row Group Server Side Yajra DataTables - laravel

Question

i have problem with yajra datatables to make row group in server side. I want row group show all employee in companies.name. and my current code like this:
public function index(DataTablesBuilderService $builder)
{
$columns = [
'name' => [
'title' => "company",
'name' => 'companies.name'
];
$dataTables = $builder
->setUrl(route('api.employee_details.data_tables', request()->all()))
->withIndex()
->setColumns($columns);
return view('employee_details.index')->with([
'dataTables' => $dataTables,
]);
}
and in blade i just call datatable like this
{!! $dataTables->table(['class' => 'table table-bordered','style' => 'width:100%', 'cellspacing' => '0']) !!}
and the script like this
{!! $dataTables->scripts() !!}
If i following the tutorial on https://datatables.yajrabox.com/eloquent/master, its possible to make row group but i dont know how to implement in server side. But is so different with my code in blade. Tutorial call datatable like this.
var template = Handlebars.compile($("#details-template").html());
var table = $('#users-table').DataTable({
processing: true,
serverSide: true,
ajax: 'https://datatables.yajrabox.com/eloquent/master-data',
columns: [
{
"className": 'details-control',
"orderable": false,
"searchable": false,
"data": null,
"defaultContent": ''
},
{data: 'id', name: 'id'},
{data: 'name', name: 'name'},
{data: 'email', name: 'email'},
{data: 'created_at', name: 'created_at'},
{data: 'updated_at', name: 'updated_at'}
],
order: [[1, 'asc']]
});
// Add event listener for opening and closing details
$('#users-table tbody').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var row = table.row(tr);
var tableId = 'posts-' + row.data().id;
if (row.child.isShown()) {
// This row is already open - close it
row.child.hide();
tr.removeClass('shown');
} else {
// Open this row
row.child(template(row.data())).show();
initTable(tableId, row.data());
tr.addClass('shown');
tr.next().find('td').addClass('no-padding bg-gray');
}
});
function initTable(tableId, data) {
$('#' + tableId).DataTable({
processing: true,
serverSide: true,
ajax: data.details_url,
columns: [
{ data: 'id', name: 'id' },
{ data: 'title', name: 'title' }
]
})
}
and the result like this and i expected like this to but in datatables server side
Thank you if you can help to help me and explain how to solve the problem code

Injecting this in your DataTable options may help you (I've tried and it's working in my case)
$(selector).DataTable({
startRender: function (rows, group) {
var grpName = rows.data().pluck('company')
.reduce(function (a, b) {
return (b === null ? '' : b);
}, '');
return $('<tr/>')
.append('<td colspan="' + columns.length + '" class="text-left"><span class="ml-10px">' + grpName + '</span></td>');
},
endRender: null,
dataSrc: 'company'
})
