This PR introduces enhancements to theTableWidget by improving its initialization and robustness, specifically addressing anAttributeError related to the_batches attribute.

Key improvements include:
Enhanced Initialization: Ensures the_batches attribute is correctly initialized in theTableWidget constructor by calling_reset_batches_for_new_page_size before it is accessed, making the widget more reliable from creation.
Improved Typing: Added explicit type hints for_batches to resolve MyPy errors, contributing to better code clarity and maintainability.
Refactored Batch Handling: Changed theto_pandas_batches call to the internal_to_pandas_batches to ensure the correctPandasBatches object is returned, satisfying type requirements and streamlining internal data handling.
Test Enhancements: Added new tests to verify the widget's row count is immutable after creation and that it gracefully handles cases with invalid total rows, ensuring the stability of the new functionality.
