The documentation on how to style a range is confusing: I think what the style_range function was doing was how to style a range of already merged cells, but this isn't clear. Specifically, it doesn't style a range of unmerged cells, which is what the function purports to do.
I've written the included function that DOES style a range of unmerged cells, and renamed the previous function for clarity.
