## Description

Noticed on [the docs](https://rich.readthedocs.io/en/stable/reference/table.html) that the `leading` parameter (available for the `Table` and `Column` objects), mention that this parameter is a `bool` type, although it appears to be an `int` type and has a default value of `0`.

This PR fixes the docstrings to annotate this parameter with the correct `int` type.
