Gt: tab_style for summary row labels

[steveputman]

Is there a way to target the label in the stub for styling in a summary row? It seems like the expected behavior when applying a style to a summary row (at least when columns = TRUE) would be to include the label in the stub.

And you can't seem to target it with cells_stub by the aggregator label, which results in the not-very-surprising error Can't bind data because some arguments have the same name.

Thanks!

Thanks for bringing this up. Unfortunately, this is the only location that currently can't be accessed by a cells_*() function, which is a shame because these labels are likely prime targets for footnotes and styling.

Also, given that this is the last location that can't be targeted, it blocks work on #176 (creating a cells_all() function).

To solve this, there are a few options I can think of here:

1. add cells_stub_summary()
2. augment cells_stub()
3. augment cells_summary()

To me, the first seems like the best option so as to not clutter the interfaces of the existing cells_*() functions.

I agree that cells_stub_summary() is the way to go here. Feels consistent with the rest of the API. Is `cells_stub_grand_summary() needed also? This would be useful for bolding a grand total row. Example:

I believe this one also prevents the user from being able to change the font table wide? @rich-iannone If so, surely this one should be labelled as a bug.
