Formatting Table Headers: The element creates table headers, which are usually displayed centered and in bold text These headers label the columns in a table The element is supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1 Here are its attributes: abbr Specifies an abbreviated name for a header (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) align Specifies the horizontal alignment Possible values are left, center, right, justify, and char (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) axis Specifies a name for a cell This attribute is normally used only with table heading cells (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) bgcolor Specifies the background color of table cells This attribute was deprecated in HTML 4.0 (Supported in XHTML 1.0 Transitional and XHTML 1.0 Frameset.) char Specifies a character to align text with respect to (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) charoff Sets the alignment offset (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) class Specifies the style class of the element (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) colspan Specifies the number of columns of the table that the header should span (the default is 1) (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) dir Sets the direction of directionally neutral text This attribute can be set to ltr, for left-to-right text, or rtl, for right-to-left text (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) headers Specifies a list of header cells (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) height Specifies the height of the header, in pixels This attribute was deprecated in HTML 4.0 (Supported in XHTML 1.0 Transitional, XHTML 1.0 Frameset.) id Specifies the ID of the element (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) lang Specifies the base language of the element (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) nowrap Specifies that the browser should not wrap text by adding line breaks This attribute was deprecated in HTML 4.0 (Supported in XHTML 1.0 Transitional and XHTML 1.0 Frameset.) rowspan Specifies the number of rows of the table that the header should span (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) scope Specifies a set of data cells for which the header cell gives header information Possible values are row, col, rowgroup, and colgroup (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) style Indicates how a browser should display the element You should set this to an inline style (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) title Specifies the title of the element (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) valign Specifies the vertical alignment of the data in the cell Possible values are top, middle, bottom, and baseline (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) width Specifies the width of the header This attribute was deprecated in HTML 4.0 (Supported in XHTML 1.0 Transitional, XHTML 1.0 Frameset.) xml:lang Specifies the base language for the element when the document is treated as XML (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.) Here's how you might create headers if you wanted to display data from the states example from Day 9, "Formatting XML by Using XSLT": State Bird Flower This example creates three table headers on top of three columns: State, Bird, and Flower TIP XHTML headers can span several columns if you use the colspan attribute Day 9 Formatting XML by Using XSLT Yesterday you saw that you can use CSS to format XML documents in the major browsers (Internet Explorer and Netscape Navigator) However, there's a native XML way to format XML documents for displayusing Extensible Stylesheet Language Transformations (XSLT), which is what you'll discuss today Here's an overview of today's topics: Transforming XML in the server, in the client, and with standalone programs Creating an XSLT style sheet Creating and applying templates Getting node values Handling multiple selections Using the match and select attributes Matching element, processing instructions, and other nodes Working with XPath Creating XPath node tests Copying nodes to the output document Making decisions in XSLT based on input data ...
