The <colgroup> tag allows you to create a column-centric table as compared to the standard HTML table which is row-centric. The columns in the table are assigned to column groups using this tag. You can have one or more groups of columns.
If you are not using the span attribute of this tag, then you can use the col tag to assign attribute values to the individual columns within the colgroup elements.
The colgroup tag can only be used inside a table element. The closing tag is optional. However, it is recommended that it always be included.
