Laravel 5.6: Using spatie laravel-permission, change names "role" and "permission"

I am using this package but I would like to change the names "roles" and "permissions" for "perfil" and "acciones" respectively in the migration tables. I changed the names in the migration tables but I can not see any changes when I use php artisan migrate. I can see this option in permission.php in config. I changed like this:

<?php

return [

    'models' => [

       /*
        * When using the "HasRoles" trait from this package, we need to know which
        * Eloquent model should be used to retrieve your permissions. Of course, it
        * is often just the "Permission" model but you may use whatever you like.
        *
        * The model you want to use as a Permission model needs to implement the
        * `Spatie\Permission\Contracts\Permission` contract.
        */

       'permission' => Spatie\Permission\Models\Permission::class,

       /*
        * When using the "HasRoles" trait from this package, we need to know which
        * Eloquent model should be used to retrieve your roles. Of course, it
        * is often just the "Role" model but you may use whatever you like.
        *
        * The model you want to use as a Role model needs to implement the
        * `Spatie\Permission\Contracts\Role` contract.
        */

       'role' => Spatie\Permission\Models\Role::class,

   ],

   'table_names' => [

       /*
        * When using the "HasRoles" trait from this package, we need to know which
        * table should be used to retrieve your roles. We have chosen a basic
        * default value but you may easily change it to any table you like.
        */

       'acciones' => 'acciones',

       /*
        * When using the "HasRoles" trait from this package, we need to know which
        * table should be used to retrieve your permissions. We have chosen a basic
        * default value but you may easily change it to any table you like.
        */

       'perfiles' => 'perfiles',

       /*
        * When using the "HasRoles" trait from this package, we need to know which
        * table should be used to retrieve your models permissions. We have chosen a
        * basic default value but you may easily change it to any table you like.
        */

       'model_has_acciones' => 'model_has_acciones',

       /*
        * When using the "HasRoles" trait from this package, we need to know which
        * table should be used to retrieve your models roles. We have chosen a
        * basic default value but you may easily change it to any table you like.
        */

       'model_has_perfiles' => 'model_has_perfiles',

       /*
        * When using the "HasRoles" trait from this package, we need to know which
        * table should be used to retrieve your roles permissions. We have chosen a
        * basic default value but you may easily change it to any table you like.
        */

       'perfil_has_acciones' => 'perfil_has_acciones',
   ],

   /*
    * By default all permissions will be cached for 24 hours unless a permission or
    * role is updated. Then the cache will be flushed immediately.
    */

   'cache_expiration_time' => 60 * 24,

   /*
    * When set to true, the required permission/role names are added to the exception
    * message. This could be considered an information leak in some contexts, so
    * the default setting is false here for optimum safety.
    */

   'display_permission_in_exception' => false,
];

But I get an error.

PD: Sorry for my bad english.
