> In the previous work of csv/json migration, CSVFileFormat/JsonFileFormat is removed in the table provider whitelist of `AlterTableAddColumnsCommand.verifyAlterTableAddColumn`:
> https://github.com/apache/spark/pull/24005
> https://github.com/apache/spark/pull/24058
> This is regression. If a table is created with Provider `org.apache.spark.sql.execution.datasources.csv.CSVFileFormat` or `org.apache.spark.sql.execution.datasources.json.JsonFileFormat`, Spark should support the "alter table add column" operation.
