row as the first column group and the next two cells into a second
column group. Any other attributes of the individual
<colgroup>
tags
then are applied to the columns contained within that group.
10.3.7.2. When to span and col
To use the
<colgroup>
tag as a container for dissimilar columns, leave
out the
span
attribute, but include within each
<colgroup>
tag an in-
dividual
<col>
tag for each column within the group. For instance, in
HTML:
<colgroup>
<col>
<col>
<col>
<col>
<colgroup>
<col>
<col>
This method creates the same number of columns in each group as we
had with the
span
attribute, but it lets you specify column attributes indi-
vidually. You can still supply attributes for all the columns via the
<col-
group>
tag, but the attributes in the
<col>
tags will override them, as
appropriate.
