   @HyukjinKwon ~See the first reply for misunderstanding, actually, 
SPARK-12225 have already support the multiple columns adding support on scala 
withColumn API in 
https://github.com/apache/spark/commit/3ca367083e196e6487207211e6c49d4bbfe31288 
 ([SPARK-22001](https://issues.apache.org/jira/browse/SPARK-22001))~ Yes, we 
only add the multiple columns adding support on scala private withColumns in 
https://github.com/apache/spark/commit/3ca367083e196e6487207211e6c49d4bbfe31288 
 ([SPARK-22001](https://issues.apache.org/jira/browse/SPARK-22001))
