>                 Key: SPARK-7133
>                 URL: https://issues.apache.org/jira/browse/SPARK-7133
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL

> Typing 
> {code}
> df.col[1]
> {code}
> and
> {code}
> df.col['field']
> {code}
> is so much eaiser than
> {code}
> df.col.getField('field')
> df.col.getItem(1)
> {code}
> This would require us to define (in Column) an apply function in Scala, and a __getitem__ function in Python.
