Laravel datatables can't create custom columns - laravel

Question

I have two tables first one simple html with no datatables, second with datables. My purpose transform first table two datatables second. But I had two main problems Grazinimo terminas column is using laravel #if and column Veiksmai using if statemens as well how can i add those as custom columns in second table.
First table code
<table class="table table-bordered">
<thead class="bg-warning">
<th>Knygos pavadinimas</th>
<th>Miestas</th>
<th>Išdavimo data</th>
<th>Grąžinimo terminas</th>
<th>Vardas</th>
<th>Pavardė</th>
<th>Kliento nr.</th>
<th>Veiksmai</th>
</thead>
<tbody>
#foreach($paskolinimai as $p)
<input type="hidden"
value="{{ $skirtumas = \Carbon\Carbon::parse(\Carbon\Carbon::today()->toDateString())->diffInDays( \Carbon\Carbon::parse( $p->terminas),false) }}">
<tr>
<td>{{ $p->pavadinimas }}</td>
<td>{{ $p->miestas }}</td>
<td>{{ $p->isdavimo_data }}</td>
#if($p->grazinimo_data != NULL)
<td>
<strong style="color: green;">Knyga grąžinta!</strong>
</td>
#elseif($skirtumas > 0)
<td>
Liko <strong style="color: crimson;">{{ $skirtumas }}</strong> dienų.
</td>
#elseif($skirtumas < 0) <td>
<strong style="color: crimson;">Terminas praėjo!</strong>
</td>
#elseif($skirtumas = 0)
<td>
<strong style="color: crimson;">Šiandien paskutinė grąžinimo diena!</strong>
</td>
#endif
<td>{{ $p->vardas }}</td>
<td>{{ $p->pavarde }}</td>
<td>{{ $p->klientasnr }}</td>
#if($p->grazinimo_data == null)
<td><a href="{{ url('patvirtinti-grazinima-'.$p->id.'-'.$p->bookid) }}"
class="btn btn-primary">Grąžinimas</a> </td>
#else
<td>
<p class="btn btn-success">Grąžinta</p>
</td>
#endif
#endforeach
</tr>
</tbody>
</table>
Second table code
<script>
$(document).ready(function () {
var darbuotojai = $('#paskolinimai').DataTable({
processing: true,
serverSide: true,
ajax:
{
url: '{!! route('get.paskolinimai') !!}'
},
columns: [
{ data: 'pavadinimas', name: 'pavadinimas' },
{ data: 'miestas', name: 'miestas' },
{ data: 'isdavimo_data', name: 'isdavimo_data' },
{ data: 'vardas', name: 'vardas' },
{ data: 'pavarde', name: 'pavarde' },
],
'oLanguage': {
'sSearch': "Paieška:",
'sZeroRecords': "Nerasta atitinkančių įrašų",
'sLengthMenu': "Rodyti _MENU_ įrašų",
'sInfo': "Nuo _START_ iki _END_ viso _TOTAL_ įrašų",
'sProcessing': "Apdorojama...",
'sLoadingRecords': "Kraunama...",
'sInfoFiltered': " - (filtruojama iš _MAX_ įrašų)",
'oPaginate': {
'sFirst': "Pirmas",
'sLast': "Paskutinis",
'sNext': "Sekantis",
'sPrevious': "Ankstesnis"
},
},
'sDom': '<"top"lfip>rt<"bottom"p><"clear">',
});
});
</script>
<table id="paskolinimai" class="table table-bordered">
<thead class="bg-warning">
<th>Knygos pavadinimas</th>
<th>Miestas</th>
<th>Išdavimo data</th>
<th>Vardas</th>
<th>Pavardė</th>
</thead>
<tbody></tbody>
</table>
</div>
So how can i add Grazinimo terminas and veiksmai correctly to the second table

Answer 1

I recommend you to use this package:
https://yajrabox.com/docs/laravel-datatables/master/installation
then go to section add column:
https://yajrabox.com/docs/laravel-datatables/master/add-column
and in your code will be like that:
->addColumn('intro', function(User $user) {
if($condtion){return $result}
})
