## Description

The `THead` wrapper identifies the `Row`s of a table that form the head of the table, as distinct from the body (`TBody`) and foot (`TFoot`) rows.

Header rows are always rendered at the beginning of the table.

### Processing expectations

This element is expected to obey the semantics of the CALS Table Model Document Type Definition, as specified by OASIS Technical Memorandum TM 9502:1995 . Header rows are often presented in an alternate typographic style, such as boldface.

In paged media, if a table spans across multiple pages, header rows are printed at the top of each new page.

## Attributes

  `VAlign` specifies the vertical alignment of text (and other elements) within the cells of this `THead`.
