[~rxin] Does the 3rd modification effect 'List' as well.
For instance,
|List(mllib, sql, ...|
should it be?
| [mllib, sql, ...|

> 1. Each column should be at the minimum 3 characters wide. Right now if the
> widest value is 1, it is just 1 char wide, which looks ugly. Example below:
> 2. If a DataFrame have more than N number of rows (N = 20 by default for
> show), at the end we should display a message like "only showing the top 20
> rows".
