> Currently, the column-related comment attribute is stored in {{Metadata}}. For example, 
> {noformat}
> StructType(
>       StructField("cl1", IntegerType, nullable = false,
>         new MetadataBuilder().putString("comment", "test").build()) :: Nil)
> {noformat}
> Compared with the existing SQL interface, it is not user friendly to add such a comment attribute when defining a {{StructField}}.
