Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The width attribute is supported in all major browsers. However, none of the browsers support the relative_length value.

Definition and Usage

The width attribute specifies the width of a <col> element.

Normally, a <col> element takes up the space it needs to display the content. The width attribute is used to set a predefined width of a <col> element.

Note: This attribute will overwrite any width set in the <colgroup> element.

Syntax

<col width="pixels|%|relative_length">

Attribute Values

Value Description
pixels Sets the width in pixels (example: width="50")
% Sets the width in percent of the surrounding element (example: width="50%")
relative_length Shares the available pixels into parts. (e.g. A table is 100 px, the first column is 20 px, the second is 50%, the available pixels will then be 30px). One part is set like this: "1*".

Example: If 30 px of space are available, you can have one "1*" and one "2*", which will be interpreted as 10 and 20 px (think of 1* as one part, and 2* as two parts).
