Dynamic HTML: The Definitive Reference

Name

<TH> — NN all IE all HTML 3.2

Synopsis

<TH>...</TH>

End Tag: Optional

The TH element is a container for content that is rendered inside one cell of a TABLE element in a format that distinguishes it as a header. Most browsers render the content as boldface. A cell is the intersection of a column and row. Other elements related to the TH element are CAPTION, COL, COLGROUP, TABLE, TBODY, TD, TFOOT, THEAD, and TR. In addition to providing a wrapper for a cell’s content, the TH element defines a number of visible attributes that apply to a single cell, often overriding similar attributes set in lesser-nested elements in the table.

Four attributes—ABBR, AXIS, HEADERS, and SCOPE—have been added to the HTML 4.0 specification in anticipation of nonvisual browsers that will use text-to-speech technology to describe content of an HTML page—a kind of “verbal rendering.” Although these attributes are briefly described here for the sake of completeness, there is much more to their application in nonvisual browsers than is relevant in this book on Dynamic HTML. Consult the HTML 4.0 recommendation for more details.
