>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: Python
>    Affects Versions: 0.7.0
>            Reporter: Tom Augspurger
>            Assignee: Phillip Cloud
>            Priority: Minor
>             Fix For: 0.8.0

> The serialize / deserialize roundtrip loses {{ df.columns.name }}
> {code:python}
> In [1]: import pandas as pd
> In [2]: import pyarrow as pa
> In [3]: df = pd.DataFrame([[1, 2]], columns=pd.Index(['a', 'b'], name='col_name'))
> In [4]: df.columns.name
> Out[4]: 'col_name'
> In [5]: pa.deserialize_pandas(pa.serialize_pandas(df)).columns.name
> {code}
> Is this in scope for pyarrow? I suspect it would require an update to the pandas section of the Schema metadata.
