How to display two models in the django admin in one table?

Question

Django

There are two models.
Both are the same, the difference is only in the name.

spoiler

class ModelA(models.Model):
    sum = models.FloatField(verbose_name='Сумма')
    com = models.TextField(verbose_name='Коментарий', blank=True, null=True)


class ModelB(models.Model):
    sum = models.FloatField(verbose_name='Сумма')
    com = models.TextField(verbose_name='Коментарий', blank=True, null=True)

Both are registered in the admin panel.

How to combine them?
That is, that there would be all objects from both models in one table, as well as that it would be possible to use filters and search.

Answer 1

Inherit them from a common root and register it in the admin panel.
