Ordinals and suffixes
Avoid expressing ordinals with superscript letters (such as 10th, 11th, and so on). Ordinals with superscript formatted in a word processor may not display correctly in some places, such as email, and the use in writing of these suffixes is becoming increasingly archaic. Do not use “th” endings or their equivalent when stating dates (i.e., do not write Join us on June 10th).
Use tables for sets of related pieces of data.
