Definition and Usage

The <col> tag defines attribute values for one or more columns in a table.
The <col> tag is useful for applying styles to entire columns, instead of repeating the styles for each cell, for each row.
The <col> tag can only be used inside a table or a colgroup element.

Browser Support

The <col> tag is supported in all major browsers.
