Definition and Usage
The <colgroup> tag specifies a group of one or more 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.
Note: The <colgroup> tag must be a child of a <table> element, after any <caption> elements and before any <thead>, <tbody>, <tfoot>, and <tr> elements.
Tip: To define different properties to a column within a <colgroup>, use the <col> tag within the <colgroup> tag.
