导入的csv文件无法在laravel中显示

Hi i recently imported a csv file to mysql and tried to display it on web using laravel

it does loop. but the data arent showing heres within my controller

$csv=tbl_name::all();<br>
return view('index')->with('csv', $csv);

and my blade file is:

@foreach($csv as $datas) <br>
  {{$datas->col1}}<br>
  {{$datas->col2}}<br>
  {{$datas->col3}}<br>
  {{$datas->col4}} <br>
  @endforeach

all i get is whitespaces with no text

i made a model too so i can access it from my controller but its empty
