Description

When we first installed and started using zeppelin (before 0.8) using z.show to display the contents of a data frame worked great! In more recent versions (I'm sorry, I don't know exactly which version it broke on), using z.show to show the contents of a data frame still produces a table, however scrolling down in that table is basically impossible. Often, it will scroll down a few rows and then jump back to the top or just freeze entirely. It seems to happen more with data frames that have many columns or large amounts of data per column (particularly with WrappedArrays)? 

Attached is a relatively small dataframe (parquet) which jumps on my zeppelin as I scroll slowly through the rows.
