Yimche opened a new pull request, #44497: URL: https://github.com/apache/arrow/pull/44497
### Rationale for this change This change is to address issue [#43985](https://arrow.apache.org/docs/dev/developers/guide/step_by_step/pr_lifecycle.html#reviews-and-merge-of-the-pull-request) in which a bug in the behaviour of equality on pyarrow tables occurs when comparing a table containing a NaN value against itself. ### What changes are included in this PR? - Removed `if` block in `arrow/cpp/src/arrow/table.cc` that forced a return true if memory address of the two items being compared were equal, no matter the data stored inside. - Added test case. ### Are these changes tested? Yes. I put a test in the `arrow/python/pyarrow/tests/test_table.py` under the `test_table_from_pydict` function, as I wasn't sure and couldn't find where else to put the test. ### Are there any user-facing changes?
