# Tables

Tables that contain artwork, chemical structures, or shading must be submitted as illustrations in an acceptable format at the modification stage. The preferred format for regular tables is MS Word. Note that a straight Excel file is not currently an acceptable format. Excel files must be embedded in a MS Word. Tables should be formatted as follows. Arrange the data so that columns of like material read down, not across. The headings should be sufficiently clear so that the meaning of the data is understandable without reference to the text. Explanatory footnotes are acceptable, but more extensive table “legends” are not. Footnotes should not include detailed descriptions of the experiment. Tables must include enough information to warrant table format. Tables are consecutively numbered with Arabic numerals (Table 1, 2, etc.), according to the order of appearance in the main text. Each table carries a short title describing its contents in relation to the main text. Except for the heading and bottom of the table, avoid horizontal dividing lines; vertical lines are completely omitted from any table. Instead, the first column is left-aligned, and other columns are generally centered. (When making tables, use “insert” command and not “tabulation”). Only the first letter of each heading is capitalized, and any units appear in parentheses after or under the corresponding heading in roman characters. Footnotes are collected under a table and referred to in the table by superscript letters (a, b, etc.). References in tables are numbered between square brackets, e.g., [5]. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared as done for conventional manuscripts.
