Scope attribute must be used correctly on table headers

Checks that scope exists only on <th> and contains one of the valid keyword values.

• Screen readers rely on scope to announce related headers
• Invalid scope values break table understanding
• Users may hear incomplete context for data cells

Use only valid values (col, row, colgroup, rowgroup) on <th> elements.

Bad Example:

<td scope="col">Name</td>
<th scope="column">Price</th>

Good Example:

<th scope="col">Name</th>
<th scope="row">Total</th>

• Using scope on <td>
• Misspelled values like column
• Combining incorrect scope with broken table structure

• Validate table header markup in devtools
• Run axe/lint checks for scope errors
• Verify spoken output for table navigation
