Blocker Description
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".

only showing top 20 rows <---- add this at the end
3. For array values, instead of printing "ArrayBuffer", we should just print square brackets:
+------------------+------------------+-----------------+ | a_freqItems| b_freqItems| c_freqItems| +------------------+------------------+-----------------+ |ArrayBuffer(11, 1)|ArrayBuffer(2, 22)|ArrayBuffer(1, 3)| +------------------+------------------+-----------------+
should be
+-----------+-----------+-----------+ |a_freqItems|b_freqItems|c_freqItems| +-----------+-----------+-----------+ | [11, 1]| [2, 22]| [1, 3]| +-----------+-----------+-----------+
