<thead> is a formatting element which contains <row> elements, which contain <entry> elements (horizontal cells) in a <table>. This row (generally only one) forms the header of a table and contains column headings. It may be used within <tgroup> and is distinct from <tbody>, which contains the rest of the table’s rows. It may also be used to provide column headings for <c>, <c01> through <c12>, and <dsc>.
Attributes
- ALTRENDER – not required. Use if the content of the element should be displayed or printed differently than the rendering established in a style sheet for other occurrences of the element.
- AUDIENCE – not required. Use to set whether the element’s contents will be visible to external users or to internal ones. Possible values are: “internal” and “external.”
- ID – not required. Creates an ID for element. Can be used for linking.
- VALIGN – not required. May be used to specify the alignment of text within the rows. Values are “top,” “middle,” or “bottom.” (<row> and <entry> may override this individually.)
Subelements
<thead> may contain <row>s.
