+If a custom field is filled in the template, such as adding an `id` field
+
+```sql
+CREATE TABLE IF NOT EXISTS `${database}`.`${table_name}`
+(
+ id,
+ ${rowtype_fields}
+) ENGINE = OLAP DISTRIBUTED BY HASH (${rowtype_primary_key})
+ PROPERTIES
+(
+ "replication_num" = "1"

upstream to complete the filling,
+and remove the id field from `rowtype_fields`. This method can be used to
customize the modification of field types and attributes.
