Is it a good idea to design database with inheritance?

For example, I have 2 tables : 'customer' and 'staff'. They are almost the same, only 2 attributes are different. So should I create another table named 'person' contains all of the same attributes of 'customer' and 'staff' then create fk keys point to this 'person'? Something like inheritance in class design.

Is there any drawback to this method ?
