Incorrect value in scope attribute

How to Fix the Problem

Use the scope attribute to associate header cells with data cells in complex tables. The allowed values are: row, col, rowgroup, or colgroup.

The Algorithm, in Simple Terms

The engine checks scope attributes for a value different than: row, col, rowgroup, or colgroup.

Why Is it Important?

The scope attribute is used to associate header cells with data cells in complex tables. The scope identifies whether the cell is a header for a row, column, or group of rows or columns.
Incorrect use of this attribute will affect the user’s ability to understand the table’s content.
