HTML colgroup tag

The HTML <colgroup> tag represents a group of one or more columns within a table in an HTML document.

It can be used to apply styles across one or more columns. This can be handy because it eliminates the need to apply the styles at the individual <td> level.

The <colgroup> tag must be used as a child of a <table> element, after any <caption> elements and before any <thead>, <tbody>, <tfoot>, and <tr> elements.

<table>
	<colgroup span="" class="">
	</colgroup>
	<tr>
		<td>Cell</td>
		<td>Cell</td>
		<td>Cell</td>
	</tr>
</table>
