> h2. Issue
> 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 different 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 on a Scala or Python process is parsed to visualize it as an HTML table format. (A screenshot of OASIS has been attached to this ticket as a file named "Screen Shot 2018-12-11 at 17.53.54.png".)
> h2. Solution
> Add an option for Dataset#show not to care about wide characters when padding them.
