Re: [I] [Python] pa.Table.to_pandas(zero_copy_only=True) never succeeds [arrow]

   I still have this problem with Pyarrow 21.0.0 and Pandas 2.3.2:
   
   ```python
   tb = pyarrow.table({'a': [1.0, 2.0, 3.0]})
   df = tb.to_pandas(zero_copy_only=True)
   
   # ArrowInvalid: Cannot do zero copy conversion into multi-column DataFrame block
   ```
