Beishao Cao updated SPARK-43270:
--------------------------------
Description:
Currently, {{df.|}} will only suggest the method of dataframe(see attached
Screenshot of databricks notebook), but {{df.column_name}} is also legal.
Hence we should override the parent {{{_}{{_}}dir{{_}}{_}}} method on Python
{{DataFrame}} class to include column names. And the benefit of this is engine
that uses {{dir()}} to generate autocomplete suggestions (e.g. IPython kernel,
Databricks Notebooks) will suggest column names on the completion {{df.|}}
