HTML <colgroup> tag
Two colgroup elements that specify different alignment and style for the three
columns in the table (notice that the first colgroup element spans two columns):
<table width="100%" border="1">
<colgroup span="2" align="left"></colgroup>
<colgroup align="right" style="color:#0000FF;"></colgroup>
<td>My first HTML</td>

Definition and Usage
The <colgroup> tag is used to group columns in a table for formatting.
The <colgroup> tag is useful for applying styles to entire columns, instead of
repeating the styles for each cell, for each row.
The <colgroup> tag can only
be used inside a table element.
The <colgroup> tag is only supported by Internet Explorer and Opera.

Tips and Notes
Tips: Add the class attribute to the <colgroup> tag, and let CSS take
care of alignment, widths, colors, etc.!
Also have a look at the <col> tag.
DTD indicates in which DTD the attribute is
allowed. S=Strict, T=Transitional, and F=Frameset.
