Synopsis

                     <colgroup>...</colgroup>
                  

Creates a column group, a structural division within a table that can be appointed attributes with style sheets or HTML. A table may include more than one column group. The number of columns in a group is specified either by the value of the span attribute or by a tally of columns <col> within the group. Its end tag is optional.

Column groups and columns were introduced by Internet Explorer 3.0 and are now proposed by the HTML 4.0 Specification as a standard way to label table structure. They may also be useful in speeding the table display (i.e., the columns can be displayed incrementally without waiting for the entire contents of the table).
