Hi @liruhui
There are two ways:
1. If the table already exists in a different DB, no configuration is required, and ShardingSphere can route correctly;
2. If you want to execute CREATE TABLE through ShardingSphere, you can only set data nodes in the sharding table rule like the configuration you provided.

```
vertical sharding database not need any configuration thit is OK ,
but vertical sharding table no configuration is error
for example
one table has three column (id, name age) , ->vertical sharding table-> table_1 has column(id,name)， table_2 has
colume(id,age) columes named "name" and “age” in different table maybe table name is different
```
```java
public static void main(String[] args) throws Exception{
Map<String, DataSource> mapDatasource = new HashMap<>();
HikariDataSource table1Database = new HikariDataSource();
table1Database.setDriverClassName();
table1Database.setJdbcUrl();
table1Database.setUsername();
table1Database.setPassword();
HikariDataSource table2Database = new HikariDataSource();
table2Database.setDriverClassName();
table2Database.setJdbcUrl();
table2Database.setUsername();
table2Database.setPassword();
mapDatasource.put("table1Database",table1Database);
mapDatasource.put("table2Database",table2Database);
DataSource dataSource = ShardingSphereDataSourceFactory.createDataSource(mapDatasource, null, null);
Connection connection = dataSource.getConnection();
connection.prepareStatement("insert into table(id,name,age) values(1,'aaaa',22)").execute();
connection.close();
}
```
```
I think this need configuraiton, but I not found API in RuleConfiration(Interface and implements class ) I do not know how to config
