## Summary Fixes IndexError when creating tables with empty list data and a provided schema. Previously, `_into_pyarrow_reader()` would attempt to access `data[0]` on empty lists, causing an IndexError. Now properly handles empty lists by using the provided schema. Also adds regression tests for GitHub issues #1968 and #303 to prevent future regressions with empty table scenarios. ## Changes - Fix IndexError in `_into_pyarrow_reader()` for empty list + schema case - Add Optional[pa.Schema] parameter to handle empty data gracefully - Add `test_create_table_empty_list_with_schema` for the IndexError fix - Add `test_create_empty_then_add_data` for issue #1968 - Add `test_search_empty_table` for issue #303 ## Test plan - [x] All new regression tests pass - [x] Existing tests continue to pass - [x] Code formatted with `make format`

Installation
pip install lancedb
Preview Releases
Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.
pip install --pre --extra-index-url https://pypi.fury.io/lancedb/ lancedb
