In many contexts, tables are the best way to represent sets of related pieces of data. However, in some contexts, other approaches are better choices.

List or table?

Tables and lists are both ways to present a set of similarly structured items; sometimes it's not obvious when to choose one presentation over the other. To decide which presentation to use, consult the following table:

Item type Example How to present
Each item is a single unit. A list of programming language names, or a list of steps to follow. Use a numbered list, lettered list, or bulleted list.
Each item is a pair of pieces of related data. A list of term/definition pairs. Use a description list (or, in some contexts, a table).
Each item is three or more pieces of related data. A set of parameters, where each parameter has a name, a data type, and a description. Use a table.

Places not to use tables

  • Don't use tables to lay out a page; use your site's standard CSS instead.
  • Usually if you have only one row of material, a table isn't the best choice for how to present it. But in some contexts (especially for consistency of layout in reference docs), it might be.
  • If you have only one column in your table, turn the table into a list.
  • Don't use tables to lay out code snippets.
  • Don't use tables to lay out long one-dimensional lists in multiple columns. For example, if you have a long list of function names, don't try to save space by splitting the list in half and presenting the two halves as a two-column table. Use tables only to present two-dimensional data—that is, material that semantically makes sense to display in rows and columns.
  • Avoid tables in the middle of a numbered procedure.

Multi-paragraph table cells

Any table cell can contain more than one paragraph.

To create multiple paragraphs, use the <p> element rather than using the <br> element. (The HTML specification describes which uses of <br> are legitimate and which aren't.)

Example of a table with some cells that contain more than one paragraph:

Attribute name Type Description
href HTML

Defines the URL for a link.

For example, go to the <a href="">Google Search</a> page.

src HTML

Defines the path of the image to be displayed.

For example, <img src="kitten.jpg">.

Introductory sentences for tables

Always precede a table with an introductory sentence that describes the purpose of the table. The sentence can end with a colon or a period; usually a colon if it immediately precedes the table, usually a period if there's more material (such as a note paragraph) between the introduction and the table. Always introduce a table with a complete sentence.

Table placement

  • When introducing a table, use a complete sentence and try to refer to the table's position, using a phrase like the following table or the preceding table.
  • Don't put a table in the middle of a sentence.
  • If your table refers to footnotes, place them immediately following the table.

Table captions

If your document contains only one table, the table doesn't need a caption. However, be sure to place the table adjacent to the text that refers to it.

If your document contains more than one table in fairly close proximity to each other, include a caption for each one, using a <caption> element as the first child of the <table> element. Start the caption with a number, in the form "<b>Table NUMBER.</b> DESCRIPTION". Use sentence case for the caption, but don't place a period at the end.

When referring to the table from text, refer to it by its number—for example, ... as shown in table 2. Do not capitalize table unless it starts a sentence.

Your site's CSS determines the styling and placement of the caption.


  <caption><b>Table 1.</b> Prehistoric birds</caption>

Table formatting

  • Don't add styling to the table element.
  • Don't merge cells. Don't use colspan or rowsspan attributes.
  • Sort rows in a logical order, or alphabetically if there is no logical order.

Table column heads

  • Use sentence case.
  • Write concise headings and omit articles (a, an, the).
  • Don't end with punctuation, including a period, an ellipsis, or a colon.
  • Use table headings for the first column and the first row only. Use the th element.
  • Include the scope attribute as appropriate, for accessibility.

Responsive tables

Where possible, use table CSS that adapts to different viewport sizes.

Linking to tables

Where possible, avoid linking to tables; instead, refer to them by table number.
