Code Review
This pull request correctly addresses a bug that caused an error when calculating the size of a pandas block with empty columns. The fix involves adding a check to skip the sampling logic for such columns, which prevents a ValueError. The PR also includes a new unit test to verify this fix and prevent regressions. The changes are sound, and I have one minor suggestion for improving code clarity.
