# HTML 5 <col> tag

## Definition and Usage

Defines the attribute values for one or more columns in a table. You can only use this element inside a table or a colgroup.

## Differences Between HTML 4.01 and HTML 5

Most of the attributes from 4.01 are no longer supported

## Tips and Notes

Note: The col element is an empty element. To create columns, you must specify td elements within a tr element.

Tip: Use this element when you want to specify different attribute values to more than one table column.

Tip: Use the <colgroup> element if you want to specify the same attribute values to a group of columns.

## Example
