How to print a table with data being displayed in column format in Laravel?

Following is my php code:

<table class="table table-striped">
<tr>
<?php

for ($i=1;$i<=8;$i++)
{
echo "<td>";
echo "<b>Col-".$i."</b><br>";
for ($j=1;$j<=15;$j++)
{

echo "Row-".$j."<br>";
}
echo "</td>";
}

?>
</tr>
</table>

So this basically prints the data values of each row header below them, column-wise that is.I want to implement the same in a Laravel view, wherein data would be passed from the controller to the view.

I tried implementing the same using the below code:

View:

<form action='/display' method="post">
<table style="table-layout: fixed; width:100%;" border=1>
 {!! csrf_field() !!}
 <thead>
   <tr>
     @foreach($todo as $todo)
     <td>
       
       @foreach($todo1 as $todo1)
       <table>
        <tr>
            <td>
             
            </td>
        </tr>

       </table>
       @endforeach
     </td>
     @endforeach
   </tr>
 </thead>
 </table>

Controller:

 <?php

namespace App\Http\Controllers;
use App\Todo;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;

//use Illuminate\Database\MySqlConnection;
class TodoController extends Controller
{
    public function index()
{

  $todo=DB::table('todos')->select('status')->groupBy('status')->get();
  //dd($todo);
  $todo1=DB::table('todos')->where('status','todo')->get();
  //dd($todo1);
  return view ('display',compact('todo1','todo'));
}
}

But I keep getting this error:

ErrorException

Trying to get property of non-object (View: lar4/resources/views/display.blade.php)

Any suggestions on what needs to be done here, I just want the format of the table like the one in the php code that I described at the start.
