docs: Register table extension.
  
          SNMP SMI provides a way to extend already existing SMI table with
          another table. This method registers dependent (extending) table
          (or type :py:class:`MibTableRow`) to already existing table.
  
          Whenever a row of the parent table is created or destroyed, the
          same mass columnar operation is applied on the extending table
          row.
  
          Parameters
          ----------
          names: :py:class:`tuple`
              One or more `tuple`'s of `str` referring to the extending table by
              MIB module name (first `str`) and `:py:class:`MibTableRow` object
              name (second `str`).
