Symfony, inherited entities and doctrine migration

Question

Under Symfony 5.0 , I use generic entity classes to unify internal projects. My generic entity (eg Table) looks like this:

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Repository\TableRepository")
 * @ORM\InheritanceType("SINGLE_TABLE")
 * @ORM\DiscriminatorMap({"generic_table": "App\Entity\Generic\Table", "table": "App\Entity\Table"})
 */
class Site
{
    //protected properties and public methods
}

And inherited class:

use App\Entity\Generic\Table as GenericTable;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Repository\TableRepository")
 */
class Table extends GenericTable
{
    //private properties and public methods
}

However, when executing this command:

php bin/console make:migration

It returns the following:

Table mybd.table already exists.

Even if the table doesn't.

Any idea? Have I forgotten an ORM statement?

A lead: we must define different table names on @ORM\\Table annotation:

@ORM\\Table(name="generic_table") for class Table

@ORM\\Table(name="table") for class Table extends GenericTable

Finally, it only creates in database table generic_table and redefines constraints on this table. But I still have issues with Repositories...
