             Summary: Improve DataFrame.show() output
                 Key: SPARK-7993
                 URL: https://issues.apache.org/jira/browse/SPARK-7993
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Reynold Xin
            Priority: Blocker


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".
