Headers

Headers (T H) are contained within the Table element and, along with the I D tag, provide assistive technology with references to column and row labels.

Code Example:

<thead>
<tr>
<th id="category1">Tutorial</th>
<th id="category2">Formats</th>
<th id="category3">Tags</th>
<th id="category4">Tools</th>
<th id="category5">Resources</th>
<th id="category6">Questions</th>
<th id="category7">About Site</th>
</tr>
</thead>

<tbody>
<tr>
<td headers="category1">Intro</td>
<td headers="category2">Stylesheets</td>
<td headers="category3">ABBR</td>
<td headers="category4">Captioning</td>
<td headers="category5">Books</td>
<td headers="category6">What</td>
<td headers="category7">Purpose</td>
</tr>
</tbody>

Browsers

Both Netscape Navigator and Internet Explorer ignore Header tags.

Adaptive Technology

Home Page Reader will read row and column headings if you press Alt + T. Jaws will read the Row and Column number of the current cell if you press Alt+Ctrl+NumKeypad5. In this example, JAWS will read the content of the first cell in the row and the current cell as "row 1, column 1, How to Intro."
