<THEAD> and </THEAD>

Description:

The <THEAD> tag defines the header elements of a table. It is used in conjunction with the <TFOOT> and <TBODY> tags (must be specified in that order). This allows the browser to understand the table layout so that more advanced scrolling and smarter printing can be performed. For example, if the body of a table is too long for the page when printed, the header and footer can be repeated on the next page.

I would not recommend using this tag as browser support appears weak or nonexistent.

Attributes:

align=alignment
Defines the horizontal alignment of the data within the cell.

CENTER Center the text.
JUSTIFY Justify the text within the cell.
LEFT Align the text to the left.
RIGHT Align the text to the right.
class=class
Indicates that the text is to be formatted using the specified class.
dir=direction
Indicates the direction (right or left) that the text is to be displayed. Useful for languages which display left to right.
event=JavaScript
When event occurs, execute the specified JavaScript.
id = "name"
You can give a text a name, which allows it to be referenced and changed in a script (dynamic HTML).
lang="lang"
Indicates the language of the text within the text.
style="style"
Defines the style in which the text will be displayed. This overrides any style elements at an "outer" level, such as from the BODY or the Cascading Style Sheet.
title="title"
You can give a text a title if you want. This provides some additional information about the text. I'm not sure why you would want to do this, but you could.
valign=n
Specifies the vertical alignment of the data within the cells.

BASELINE First line of each element in the cell aligned with a baseline.
BOTTOM Align elements with bottom of cell.
MIDDLE Align to middle.
TOP Align to the top.
