Variations
The COL element is part of the new proposed standard
tables structure. It is not widely implemented in existing browsers.
The order of placement of a series of COL elements within the TABLE
content (or within a COLGROUP) is significant, and describes the columns
in the TABLE DIR presentation order, first to last.
SPAN is a positive integer that specifies how many columns this element
applies to, defaulting to one. SPAN=0 implies all columns from the
current column up to and including the last column.
WIDTH is a decimal number which specifies the width
of each column in the span.
The default units is pixels, but may be specified by a suffix on the number.
The standard defined units suffixes include:
pt=points,
pi=picas,
in=inches,
cm=centimeters,
mm=millimeters,
em=em units,
px=screen pixels.
In addition, the special suffix of an asterisk may be used
to specify a number to be used as a multiplier of a "standard" column width.
This is used to specify the widths of columns proportionately relative
to each other.
If a number does not accompany the asterisk it defaults to one.
Specifying WIDTH="0*" forces the column to its minimum width.
ALIGN and VALIGN define the alignment of text within a table cell.
If ALIGN=char, CHAR specifies the alignment character which defaults
to the decimal point for the current language. CHAROFF is a decimal
number that specifies the offset for the alignment character from the
beginning of the table cell in the DIR direction. Units may be specified
using the standard defined units suffixes plus the special suffix of the
percent sign indicating the percentage of offset within the cell from the
beginning of the cell.
