--------------------------------
Summary: [C++][Python] Slicing a table with no columns returns a
table with incorrect length.
Key: ARROW-15412
URL: https://issues.apache.org/jira/browse/ARROW-15412
Project: Apache Arrow
Issue Type: Bug
Components: C++, Python
Affects Versions: 6.0.1
Reporter: A. Coady
Python `[:]` slicing works on tables with no columns, because the slice inputs
are normalized. But the `slice` method is inconsistent.
{code:python}
In [1]: import pyarrow as pa
In [2]: table = pa.table({'col': range(3)})
In [3]: table.slice(1).num_rows
Out[3]: 2
In [4]: table.select([])[1:].num_rows
Out[4]: 2
In [5]: table.select([]).slice(1).num_rows
Out[5]: 3
In [6]: table.select([]).slice(1, 4).num_rows
Out[6]: 4
