   ## Question
   
   To configure binding table groups using 
org.apache.shardingsphere.sharding.api.config.ShardingRuleConfiguration#bindingTableGroups,
 you can follow these steps. This configuration is necessary because custom 
sharding logic (implemented via 
org.apache.shardingsphere.sharding.api.sharding.standard.StandardShardingAlgorithm)
 is being used. The table name format is "logictablename_year_quarter". In the 
org.apache.shardingsphere.sharding.rule.TableRule#createTableDataNode logic, a 
regular expression Pattern.compile("\\d+$") is used to parse the prefix, 
leading to "logictablename_year" being considered as the prefix, which results 
in the failure of 
org.apache.shardingsphere.sharding.rule.ShardingRule#isValidActualTableName 
validation.
