-## Applicability
-
-The rule applies to any HTML element that is a [descendant](https://dom.spec.whatwg.org/#concept-tree-descendant) in the [flat tree](https://drafts.csswg.org/css-scoping/#flat-tree) of an element having a [semantic role](#semantic-role) of either [table](https://www.w3.org/TR/wai-aria-1.1/#table) or [grid](https://www.w3.org/TR/wai-aria-1.1/#grid), and is [visible](#visible) as well as [included in the accessibility tree](#included-in-the-accessibility-tree), where the element has any of the following [semantic roles](#semantic-role):
-
-- [cell](https://www.w3.org/TR/wai-aria-1.1/#cell)
-- [gridcell](https://www.w3.org/TR/wai-aria-1.1/#gridcell)
-- [rowheader](https://www.w3.org/TR/html-aria/#index-aria-rowheader)
-- [columnheader](https://www.w3.org/TR/html-aria/#index-aria-columnheader)
-
-## Expectation
-
-The target element is either the row or column header for cells that is a [descendant](https://dom.spec.whatwg.org/#concept-tree-descendant) in the [flat tree](https://drafts.csswg.org/css-scoping/#flat-tree) of the same [table](https://www.w3.org/TR/wai-aria-1.1/#table) or [grid](https://www.w3.org/TR/wai-aria-1.1/#grid) element, as that of the target element.
-
-**Note:** Assigning headers cells to data cell is performed as per algorithm - [Forming relationships between data cells and header cells](https://html.spec.whatwg.org/multipage/tables.html#header-and-data-cell-semantics).
-
-## Assumptions
-
-_There are currently no assumptions._
-
-## Accessibility Support
-
-_There are no major accessibility support issues known for this rule._
-
-## Background
-
-- [Understanding Success Criterion 1.3.1: Information and relationships](https://www.w3.org/WAI/WCAG21/Understanding/info-and-relationships.html)
-- [H43: Using id and headers attributes to associate data cells with header cells in data tables](https://www.w3.org/WAI/WCAG21/Techniques/html/H43)
-- [Forming relationships between data cells and header cells](https://html.spec.whatwg.org/multipage/tables.html#header-and-data-cell-semantics)

-## Test Cases
-
-### Passed
-
-#### Passed Example 1
-
-The column header element has corresponding cell, within the same `table` element.
-
-```html
-<table>
-	<tr>
-		<th>Time</th>
-	</tr>
-	<tr>
-		<td>05:41</td>
-	</tr>
-</table>
-```
-
-#### Passed Example 2
-
-Each column header element has corresponding cells, within the same `table` element.
-
-```html
-<div role="table">
-	<div role="rowgroup">
-		<div role="row">
-			<span role="columnheader">Month</span>
-			<span role="columnheader">Top Temperature</span>
-		</div>
-	</div>
-	<div role="rowgroup">
-		<div role="row">
-			<span role="cell">July</span>
-			<span role="cell">40 C</span>
-		</div>
-		<div role="row">
-			<span role="cell">August</span>
-			<span role="cell">45 C</span>
-		</div>
-	</div>
-</div>
-```
-
-#### Passed Example 3
-
-Each column header element has corresponding cells within the same table element. In this example the column headers have cells that span multiple columns.
-
-```html
-<table>
-	<thead>
-		<tr>
-			<th>Projects</th>
-			<th>Exams</th>
-		</tr>
-	</thead>
-	<tbody>
-		<tr>
-			<td colspan="2">15%</td>
-		</tr>
-	</tbody>
-</table>
-```
-
-#### Passed Example 4
-
-Each row and column header element has corresponding cells, within the same element having a [semantic role](#semantic-role) of `grid`.
-
-```html
-<table role="grid">
-	<thead role="rowgroup">
-		<tr role="row">
-			<td></td>
-			<th role="columnheader">Breakfast</th>
-			<th role="columnheader">Lunch</th>
-			<th role="columnheader">Dinner</th>
-		</tr>
-	</thead>
-	<tbody role="rowgroup">
-		<tr role="row">
-			<th scope="row" role="rowheader">Day 1</th>
-			<td>8:00</td>
-			<td>13:00</td>
-			<td>18:00</td>
-		</tr>
-	</tbody>
-</table>
-```
-
-### Failed
-
-#### Failed Example 1
-
-One of the column headers ("Column 2"), does not have corresponding cell within the same `table` element.
-
-```html
-<table>
-	<thead>
-		<tr>
-			<th>Column 1</th>
-			<th>Column 2</th>
-		</tr>
-	</thead>
-	<tbody>
-		<tr>
-			<td>15%</td>
-		</tr>
-	</tbody>
-</table>
-```
-
-### Inapplicable
-
-#### Inapplicable Example 1
-
-The rule does not apply to table element that is not [included in the accessibility tree](#included-in-the-accessibility-tree).
-
-```html
-<table role="presentation">
-	<tr>
-		<th>Time</th>
-	</tr>
-	<tr>
-		<td>12:00</td>
-	</tr>
-</table>
-```
-
-#### Inapplicable Example 2
-
-The rule does not apply to table element that is not [visible](#visible) in page.
-
-```html
-<html>
-	<style>
-		.notInPage {
-			position: absolute;
-			left: -9999px;
-			top: -9999px;
-		}
-	</style>
-
-	<body>
-		<table class="notInPage">
-			<tr>
-				<th>Time</th>
-			</tr>
-			<tr>
-				<td>24:00</td>
-			</tr>
-		</table>
-	</body>
-</html>
-```
