+### Added

+- Added two new date methods — `apmonthtab` and `apdatetab`. These two are identical to `apmonth` and `apdate` except months are output in AP's tabular format instead. Instead of `Sept.` you get `Sep`, etc.
+- The logic for determining the correct suffix in `ordinal` has been extracted and made into its own method called `ordinalsuffix`. This makes it possible to access the correct suffix for a number without modifying the original value. Great for if you'd like to style the number and suffix differently, or just want to output them separately. Credit to @sawyerclick for the suggestion in #283!
