How to use global prefix for tables in Laravel 5

New in Laravel. Probably a silly question. I had setup database like this:

'mysql' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '3306'),
        'database' => 'mydb',
        'username' => 'myusername',
        'password' => 'mypassword',
        'charset' => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix' => 'admin',
        'strict' => false,
        'engine' => null,
    ],

Notice 'prefix' => 'admin'. This is because I want all tables related to the website's control panel be prefixed with admin, e.g: admin_users, admin_log, etc...

But I'm stuck at the very beginning. I'm trying to create migrations via artisan but it's not creating the tables with the prefix.

php artisan make:migration create_users_table --create=users

I'm expecting that to create a table named admin_users. But it's not.

Am I doing this right?
