  Can someone help me with this?
  I searched on the Internet but I didn't find anything that helped me.

  <p>my table:</p>
  
  <pre><code>&lt;?php
  
  use Illuminate\Support\Facades\Schema;
  use Illuminate\Database\Schema\Blueprint;
  use Illuminate\Database\Migrations\Migration;
  
  class CreateServiceTable extends Migration

      /**
       * Run the migrations.
       *
       * @return void
       */
      public function up()
      {
          Schema::create('service', function (Blueprint $table) {
              $table-&gt;increments('id');
              $table-&gt;string('title');
              $table-&gt;string('description');
              $table-&gt;string('icon');
              $table-&gt;class('class');
              $table-&gt;timestamps();
          });
      }
  
      /**
