This issue tracks DataFrame.pivot_table (#386)
The actual implementation can handle values as a list but it's disabled right now with this condition :

if isinstance(values, list) and len(values) > 1:
    raise NotImplementedError('Values as list of columns is not implemented yet.')

We need to implement multi-level columns before updating pivot_table

Hi @garawalid,
We recently added a basic multi-index support in columns (#590).
Does that help you submit a PR?

Update DataFrame.pivot_table() (#635)
b7fc773 
Resolves #511, #636. 
In the test, the `kdf` is converted to Pandas DataFrame in order to use `sort_index()`. I'll update the test once #634 resolved.
