Dear,
Since I already told you the logicTableName, you should treat it as exists,
even sometimes, the logicTableName not exists in SQL, but this is my intention.
e.g. I want to use the sharding rules of table-a to shard table-b, this should
be allowed.
Hope you can double think my suggestion. This feature should broadly promote
the usage of Sharding-jdbc.
