TABLES

Tables present information in rows and columns. They provide for very organized displays of precise data. Data in tabular form is usually more easily understood than the same information presented in text.

Example

Tips for Designing Tables Define rows and columns based on the purpose. Use appropriate headings for rows and columns. Use lines or white space to separate headings from data and to separate rows and columns. Use like units of measurement for parallel or compared data. Align decimals vertically within columns. Use zeros, dashes, ellipses, or NI and NA to indicate information that is missing or not applicable. Use footnotes for headings and entries that must be clarified.

Always try to keep tables as simple as possible. Summary tables are placed in the body of the document, while tables with ancillary information are placed in the appendices or attachments.

Whenever possible, tables should be oriented horizontally on the page. Use row headings and column headings to identify the information listed in each row and column. Where space is limited, abbreviations may be used.

Rows and columns should be organized logically so that the purpose of the table is clear and the table is easy to read. Decimals should be aligned vertically within columns.
