Andreas created ARROW-4867:
------------------------------
Summary: Table.from_pandas() column order not respected
Key: ARROW-4867
URL: https://issues.apache.org/jira/browse/ARROW-4867
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.12.1
Reporter: Andreas
Starting with 0.12, the order of the columns in {{Table.from_pandas}} is no
longer identical to the order of the colums given in the {{columns}} argument.
This used to be the case in previous versions.
0.12:
{code:java}
In [1]: pyarrow.Table.from_pandas(pd.DataFrame(dict(a=[1],b=[2])),
columns=['b', 'a'])
Out[1]:
pyarrow.Table
a: int64
b: int64{code}
0.11:
{code:java}
In [1]: pyarrow.Table.from_pandas(pd.DataFrame(dict(a=[1],b=[2])),
columns=['b', 'a'])
Out[1]:
pyarrow.Table
b: int64
a: int64{code}
