make sure you have 3.23.28 or later, and use
replicate-wild-do-table=db_name.%.
--replicate-do-table=name
Tells the slave thread to restrict replication to the

updates to tables in all databases that start with foo
and whose table names start with bar.
--replicate-wild-ignore-table=name
Tells the slave thread to not replicate to the tables
that match the given wildcard pattern. To specify more
than one table to ignore, use the directive multiple

may not be valid for connecting to the slave from the
master or other hosts.

NO = Prohibit update of a VIEW, which does not contain a
key of the underlying table and the query uses a LIMIT
