HTML tag

When writing in HTML, the tag is used to denote a group of columns within a table. It is useful when you want to format many columns at the same time. The following sections contain information about this tag, including an example of it in use, as well as related attributes and browser compatibility.

Example of code

As the HTML code indicates, the entire table has a background color of white and the first column is "painted" grey. The table itself has one of our CSS classes applied to it to improve its appearance.
