HTML5: th – table header cell

th – table header cell # T

The th element represents a header cell in a table.

Content model #

th = (normal-character-data & common.elem.flow *) & th.attrs

Attribute model #

th.attrs = common.attrs & scope ? & colspan ? & rowspan ? & headers ? & common.attrs.aria.implicit.th ?

Element-specific attributes #

scope = "row" | "col" | "rowgroup" | "colgroup": Specifies what set of cells the th element applies to.
colspan = integer.positive: Specifies the number of adjacent columns “spanned” by its th element.
rowspan = integer.non-negative: Specifies the number of following rows “spanned” by its th element.
headers = idrefs: Identifies one or more th elements that apply to its th.

Tag omission #

A th element must have a start tag.

A th element's end tag may be omitted if the th element is immediately followed by a td or th element, or if there is no more content in the parent element.

Permitted contexts #

tr = (td | th)*
