TABLES 

G OOD TABLES ARE ESSENTIAL to scientific 

reports simply because some information is presented best in tabular form. This section contains 

recommendations for designing tables and provides 

examples of tables (tables 8-13) that incorporate features likely to be used by authors preparing reports 

for the Geological Survey. These examples are modified from tables in published Survey books. They can 

only hint at the diversity of formats possible. The recommendations in this section are adapted from the U.S. 

GPO Style Manual (1984, p. 173-199), which is the 

principal guide and source of detailed instructions for 

Survey tables but which contains more information 

than most authors need to know. Stratigraphic tables 

and measured sections are discussed in the section on 

"Stratigraphic Nomenclature and Description." Table 7, 

from the U.S. GPO Style Manual (1984, p. 192-193), 

gives some terms and formats used in Survey publications; varied needs may cause minor differences. 

Simplicity. Simple tables generally are more effective than complex ones. A table should deal with a 

single subject or should bring together related information for purposes of comparison. Several small 

tables generally are better than one big one. Editorial 

advice in the design of tables when your manuscript 

is still in draft may save time and effort. 

Numbers and titles. Most tables are numbered 

and titled for ease of reference. The only tables that 

may be unnumbered and untitled are column-width 

tables that immediately follow their only citations. 

Such tables are not listed in the "Contents" of the 

report. A report may contain both numbered and 

unnumbered tables. 

Every table, whether numbered or unnumbered, 

must be cited at least once in the text. Tables are 

numbered in the order cited, and Arabic numerals are 

used. The word "table" is lowercase in the text and is 

never abbreviated in Survey reports. 

Titles of all numbered tables should be listed in the 

"Contents" almost exactly as they appear above the 

tables, but explanatory phrases in parentheses or set 

off by commas, such as "in weight percent," may be 

omitted from the "Contents." 

Because a table should be able to stand alone, its 

title should be reasonably complete and should contain 

no unusual acronyms and abbreviations. At the same 

time, a title should be concise. Information that supplements a title belongs in a headnote; generally, a 

title should not take a footnote. Similar tables in the 

same report should have similarly worded titles, but 

each title should be unique. A title has no concluding 

punctuation. 

The essence of a table is the logical arrangement 

of its information. The columns and rows (which are 

usually labeled by the entries in the first column) 

should be in some meaningful order. This order 

should be reflected in the order of items in the 

table title. 

Headnotes. A headnote (if needed) is placed below 

the title to provide information pertaining to the title, 

to the table as a whole, or to the column headings. 

The headnote should explain acronyms, abbreviations, 

and symbols used, and it is a good place to mention 

methods used and to credit analysts. The headnote is 

enclosed in square brackets unless it is very long; no 

period precedes the closing bracket unless the headnote ends in an abbreviation followed by a period. 

Footnotes. Explanations of individual entries in 

the table belong in footnotes. Footnotes usually are 

preceded by superscript Arabic numerals, but to avoid 

ambiguity, symbols or lowercase letters may be used. 

Footnote numbering in each table begins with the 

numeral 1. The footnote reference numbers increase 

from left to right in the column headings, then in the 

first line of the table body, and then across each succeeding line. The superscript numerals follow words 

and symbols and precede figures (tables 11, 12); if 

they stand alone, they are enclosed in parentheses 

(table 8). 

Column headings. Every column in a table after 

the first column needs a centered heading, and in 

many tables the first column also has a centered 

heading. If two or more layers of headings (stacked 

headings) are appropriate, as in tables 9, 11, and 12, 

the highest heading (spanner head) is centered above 

a horizontal line that spans the headings of columns 

to which the heading pertains. For readability, column 

heads usually are horizontal, but to save space, they 

may be turned sideways (table 9). Down rules (vertical 

lines) are usually avoided, but some tables, such as 

table 9, may need them. 

Columns may be numbered for ease of reference in 

the text or to avoid long column heads. If columns 

are numbered, the Arabic numerals may be explained 

below the table and its footnotes. 

The units of measurement used must be provided 

within the table. They may be in the column headings, 

abbreviated if necessary to save space (table ll), or in

Table 7. Definition and parts of a table 

[To define and describe fully all of the many parts, terms, and details that enter into tabular presentation is difficult to explain jn a few 

words or to understand readily wthout an accompan 'ng vlsual example. The example shown is directed at people concerned with the con- struction and makeup of tables and with guidelines igntifying tabular terms and details. Many of the terms can be applied to any form of 

tabular matter]

the title, headnote (table 12)) footnotes, or subheads 

between table-width cross rules (table 10). 

Blank spaces and leaders. Spaces may not be left 

blank within the body of a table except in first or last 

columns containing words (reading columns). If no 

data are available, the space should be occupied by 

symbols such as leaders or suitable abbreviations such 

as "n.d." These symbols and abbreviations should be 

explained in the headnote. 

Besides occupying spaces for which data are not 

available, leaders follow words in reading columns to 

guide the eye across the table; the final word of each 

entry in a last (far right) reading column is followed 

by a period or a question mark. Either dot leaders or 

dash leaders are acceptable, but only one style is 

generally used within a table and report. On word 

processors, dots generally are easier to type than 

dashes. If any entry in a reading column runs onto 

a second line, the overrun is indented. In tables 

containing a single reading column as the first 

column, leaders follow the bottom line of the entry 

consisting of words (table 12). In tables having more 

than one reading column, other entries align with the 

top lines of multiline entries in the reading columns, 

and the top lines are not followed by leaders (tables 

11, 13). Multiline entries end with periods or question 

marks. Single-line entries in reading columns are 

followed by leaders as usual if space permits. The 

period is omitted immediately before the leaders 

(tables 9, 13). 

Like leaders, double spaces at regular intervals may 

enhance a table's readability. A long table consisting 

mostly of single-line entries may have double spaces 

after every five lines of type. The interval should be 

chosen to provide a good appearance or to group 

similar entries, but it should not vary within a table 

except to keep single lines from following a double 

space at the end of a table section. 

Subheads between table-width cross rules. 

Under the column headings, tables may be divided 

horizontally by subheads between pairs of lines that 

span columns (table 10). Each subheading pertains to 

all items between it and the next subhead beneath it. 

A table containing such subheads can be used to 

compare several kinds of information for the same 

sample, time, or area, because each column heading 

applies to every entry in its column, no matter which 

spanner head the entry is under. 

General information. Manuscript tables should be 

submitted double spaced, and margins on all sides 

should be at least an inch wide to leave room for 

editorial marks qnd instructions for the typesetter. 

Each table should be on a separate page or group of 

pages. Oversize sheets are fine. If a table must 

continue onto a second page, the title followed by 

"-Continued" should appear at the top of the second 

page, and all column headings should be repeated. 

The headnote should also be repeated, if it is not 

too long. 

Camera-ready tables are used in many Survey reports. Persons preparing camera-ready tables should 

seek editorial advice. The following tables illustrate 

most formats likely to be presented in Survey reports.

because dash leaders are used in tables 8 and

Table 13 shows: 

How to double up a table under one title. 

Alignment of a table containing several reading 

columns that have overruns. 

Use of headings in first column followed by 

colons; a single entry after a colon is run in 

(Taylorsville basin: ASH-I), whereas several 

entries after a colon are placed on separate lines. 

Clearing (avoiding repetition of) the first part of a 

sample number containing a dash but not clearing 

a number that has no dash (NB584-14 as opposed 

to SP1). 

) Use of "Continued." 

) Use of "do" and "Do." 

Use of figures even at the beginning of a readingcolumn entry; "146" is not written out the way it 

would be at the beginning of a text sentence. 

) No period after "Conn," "Mass," and "do" before 

leaders. 

A logical arrangement of data; basins are listed 

from south to north.
