Specifying the columns - widths using the colspec attribute allows browsers to start - displaying the table without having to wait for last row. - - The colspec attribute is a list of column widths and alignment - specifications. The columns are listed from left to right with - a capital letter followed by a number, e.g. COLSPEC="L20 C8 L40". - The letter is L for left, C for center, R for right alignment of - cell contents. J is for justification, when feasible, otherwise - this is treated in the same way as L for left alignment. - Column entries are delimited by one or more space characters. - - The number specifies the width in en's, pixels or as a - fractional value of the table width, as according to the - associated units attribute. This approach is more compact - than used with most SGML table models and chosen to simplify - hand entry. The width attribute allows you to specify the - width of the table in pixels, en units or as a percentage - of the space between the current left and right margins. - - To assist with rendering to speech, row and column headers - can be given short names using the AXIS attribute. The AXES - attribute is used to explicitly specify the row and column - names for use with each cell. Otherwise browsers can follow - up columns and left along rows (right for some languages) - to find the corresponding header cells. - - Table content model: Braille limits the width of tables, - placing severe limits on column widths. User agents need - to render big cells by moving the content to a note placed - before the table. The cell is then rendered as a link to - the corresponding note. - - To assist with formatting tables to paged media, authors - can differentiate leading and trailing rows that are to - be duplicated when splitting tables across page boundaries. - The recommended way is to subclass rows with the CLASS attribute - For example: <TR CLASS=Header>, <TR CLASS=Footer> are used for - header and footer rows.
