> https://issues.apache.org/jira/browse/SPARK-25108 makes Dataset#show care
> about wide characters when padding them. That is useful for humans to read a
> result of Dataset#show. On the other hand, that makes it impossible for
> programs to parse a result of Dataset#show because each cell's length can be
> difference from its header's length. My company develops and manages a
> Jupyter/Apache Zeppelin-like visualization tool named "OASIS"
> ([https://databricks.com/session/oasis-collaborative-data-analysis-platform-using-apache-spark]).
> On this application, a result of Dataset#show is parsed to visualize it as
> an HTML table format.
> So, it is preferable to add an option for Dataset#show not to care about wide
> characters when padding them by adding a parameter such as "fixedColLength"
> to Dataset#show.
