U.S. Government Printing Office Style Manual/Leaderwork
(See also Chapter 9 "Abbreviations and Letter Symbols" and Chapter 13 "Tabular Work")
Leaderwork is a simple form of tabular work without boxheads or rules and is separated from text by 4 points of space above and below in solid matter and 6 points of space in leaded matter. It consists of a reading (stub) column and a figure column, leadered from the bottom line. It may also consist of two reading columns, aligning on the top line. In general, leaderwork (except indexes and tables of contents, which are set the same style as text) is governed by the same rules of style as tabular work. Unless otherwise indicated, leaderwork is set in 8 point. The period is omitted immediately before leaders.
No bearoff is required at the right in a single reading column.
A figure column is at least an en quad wider than the largest group of figures, but not less than 3 ems in single columns and 2 ems in double-up columns. Total rules are to be the full width of all figure columns.

The use of continued heads in leaderwork is not necessary.
The abbreviation do. is indented and capitalized in the stub. It is capitalized and cleared in last reading column.
In a column containing mixed amounts (as money, tons, gallons, etc.) the figures are aligned on the right, and the dollar mark or other symbol is repeated before each sum of money. If several sums of money are grouped and added or subtracted to make a total, they are separated from the nonmoney group by a parallel rule, and the symbol is placed on the first figure of the separated group only.
If two columns of sums of money add or subtract one into the other and one carries points and ciphers, the other should also carry points and ciphers.
Flush items clear the figure column.
Subheads are centered in full measure.
Footnotes to leaderwork follow the style of footnotes to tables.
If the leaderwork runs over from one page to another, the footnotes will be placed at the bottom of the leadered material.[1]
Units of quantity or other words over a stub or figure column are set italic.
