Thomas Buhrmann commented on ARROW-2572:
----------------------------------------
Another (discoverable) workaround was to convert the table to record batches
and then use the from_batches function, but yes, the aliases would be much
nicer.
Perhaps next week I may try to set up a dev environment and see whether I can
contribute. Thanks for the nudge ;)
> [Python] Add factory function to create a Table from Columns and Schema.
> ------------------------------------------------------------------------

> Key: ARROW-2572
> URL: https://issues.apache.org/jira/browse/ARROW-2572
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Affects Versions: 0.9.0
> Reporter: Thomas Buhrmann
> Priority: Minor
> Labels: beginner
>
> At the moment it seems to be impossible in Python to add custom metadata to a
> Table or Column. The closest I've come is to create a list of new Fields (by
> "appending" metadata to existing Fields), and then creating a new Schema from
> these Fields using the Schema factory function. But I can't see how to create
> a new table from the existing Columns and my new Schema, which I understand
> would be the way to do it in C++?
> Essentially, wrappers for the Table's Make(...) functions seem to be missing.
