Heads follow the style of the tables as to the use of figures and abbreviations.
Punctuation is omitted after centerheads. Flush entries and subentries over subordinate items are followed by a colon (single subentry to run in, preserving the colon), but a dash is used instead of a colon when the entry reads into the matter below.

In reading columns if the centerhead clears the reading matter below by at least an em, the space is omitted; if it clears by less than an em, a space is used. If an overrun, rule, etc., in another column, or in the same column, creates a blank space above the head, the extra space is not added.
Units of quantity and years used as heads in reading and figure columns are set in italic with space above and no space below.
The rules are used here to aid readability.
