Actually, it turns out that integer column names are preserved:
```python
>>> pa.Table.from_pandas(pd.DataFrame({'123': [1]})).to_pandas().columns
Index(['123'], dtype='object')
>>> pa.Table.from_pandas(pd.DataFrame({123: [1]})).to_pandas().columns
Int64Index([123], dtype='int64')
```
Is this also the case here?
