HTML <th> axis Attribute

The axis attribute of the <th> tag was used to categorize header cells and define relationships between headers and data cells. It is now obsolete and not supported in HTML5.

• Used to define a category or group name for a header cell.
• Helped associate header cells with related data cells.
• Used only with the <th> element.

Note: The axis attribute is obsolete in HTML5; use scope or headers attributes instead.

<th axis="category_name">

Attribute Values:

• category_name: It is used to specify the category name.
