Inneke points out an error I should have caught in the table example I
sent earlier today:

<blockquote>
Did not you see  that the th-tag is not closed at all, so it can never
be 
valid or well-formed? i copied the code to a page i am working on and
the 
validator also told me that the </th>-tag is  omitted.


Besides; it misses a caption tag, headers attribute and
summary-attribute 
</blockquote>

You're right, I should have caught the error. Thanks for pointing it
out. I think it was caused by sloppy copy-and-paste.

I'm attaching an HTML file that closes the unclosed <th> element; the
<table> element now includes a summary attribute and a <caption>
element.  There is no headers attribute on the <th> element because it's
not required-- this is a simple table with just one level of headers.

I submitted this file to validator.w3.org, and the validator returned
the following message:

<blockquote>
This Page Is Valid
HTML 4.01
Transitional!
</blockquote>

Nevertheless, JAWS 6.10 still reports that  "There are no tables on this
page." It does this when I press the letter "t," which serves as a
hotkey to jump from table to table.

When I arrow down the page from the top, JAWS speaks the caption text.
It does not read the summary attribute (as it does for tables that it
recognizes). It reads the contents of the cells in the table. But when I
use the table-navigation keys (alt+ctrl+leftArrow or rightArrow) JAWS
says, "Not in a table."

Hello John,

You wrote:

<code>
<table>
    <thead>
        <tr>
            <th colspan="4" scope="col">Building Accessible Web Sites
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>HTML</td>
            <td>PDF</td>
            <td>MS Word</td>
            <td>DAISY</td>
        </tr>
    </tbody>
</table>
</code>


Did not you see  that the th-tag is not closed at all, so it can never
be 
valid or well-formed? i copied the code to a page i am working on and
the 
validator also told me that the </th>-tag is  omitted.


Besides; it misses a caption tag, headers attribute and
summary-attribute 
for making the table-code also better  understandable for non-visual
UAs.
