php artisan make:migration table_name_here

Only generates the migration file/class and its stubbed methods up()/down(). You need to code out your schema.

https://laravel.com/docs/5.4/migrations#migration-structure

    public function up()
    {
        Schema::create('companies', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->timestamps();

        });
    }

When your schema is done within the up() method, you can then run the migration with

php artisan migrate

Migration only creates the Migration Class. You need to create the schema by yourself in the up function. It's easy. You can get a sample schema from the documentation.
