* chore: blob.display to support width and height params

* wording

Fixes internal issue 401055880

This PR expands the functionality of the `index_col` parameter in the `read_csv` method. 

New capabilities include:
1.  **Multi-column Indexing:** `index_col` now accepts an iterable of strings (column names) to create a MultiIndex. (Fixes internal issue 338089659)
2. **Integer Indexing:** Support for a single integer index or an iterable of integers (column positions) is also explicitly included/verified. (Fixes internal issue 404530013)
3.  **Pandas Compatibility:** Adds tests to ensure that the behavior of `index_col` when set to `False`, `None`, or `True` aligns with standard Pandas behavior. (Fixes internal issue 338400133)
