A.5.)VERTICAL ALIGNMENT. Align a column of numbers vertically on their real or implieddecimal points by aligning on the rightmost numeral, so that readers can compare the valuesin the column. If all numerical values in a column have a zero before a decimal point, youmay omit the zeros (see figure A.13).Align dollar signs, percent signs, degrees, and so on. But if they occur in every cell in thecolumn, delete them from the cells and give the unit as a tag in the column head (see 26.2.4,table 26.2, and figure A.13).If the data consist of words, center each column under the column head. If any items haverunovers, align each column flush left (see table 26.1).26.2.7 FootnotesIf a table has footnotes, position them flush left, single-spaced. Leave a blank line between thebottom rule of the table and the first note, and also between notes. Footnotes may bepresented in a smaller typeface than the rest of the text; consult your local guidelines.Footnotes for tables can be of four kinds: (1) source lines (discussed in 26.1.3), (2) generalfootnotes that apply to the whole table, (3) footnotes that apply to specific parts of the table,and (4) notes on levels of statistical significance. If you have more than one kind of note, putthem in that order.GENERAL NOTES. General notes apply to the entire table. They define abbreviations, expandon the table title, specify how data were collected or derived, indicate rounding of values, andso on. Gather all such remarks into a single note. Do not put a note number (or other symbol)anywhere in the table or the table title, or with the note itself. Simply begin the note with theword Note (capitalized, in italics, followed by a colon). See also table 26.3.Note: Since not all data were available, there is disparity in the totals.SPECIFIC NOTES. Notes to explain specific items in a table can be attached to any part of thetable except the table number or title. Designate such notes with lowercase, superscript lettersrather than numbers, both within the table and in the note itself. Do not begin the note withthe word note but with the same superscript letter, with no period or colon following.a Total excludes trade and labor employees.If you include more than one such note in a table (as in table 26.2), use letters in sequentialorder, beginning at the upper left of the table, running left to right and then downward, row byrow. If a note applies to two or more items in the table, use the same letter for each item; if itapplies to all items in a column or row, put the letter in the relevant column head or stubentry.NOTES ON STATISTICAL SIGNIFICANCE. If you include notes on the statistical significanceof your data (also called probability notes), and if the significance levels are standard,
