I'm not sure I understand. Why would using two <alt> elements, as in my
previous message, not work in this particular case?

Btw, something cute about this example is that it shows how easily an author
could provide even much richer equivalents, serving more browsing
environments better:

<img id="mergedcells" src="mergedcells.gif">
<!-- anything or nothing -->
<alt for="mergedcells" title="short textual equivalent"
type="text/html">blah</alt>
<alt for="mergedcells" title="long description" type="text/html>blah,
blah</alt>
<alt for="mergedcells" title="tabular equivalent" type="text/html">
<table border="1" summary="This table gives some statistics about fruit
flies: average height and weight, and percentage with red eyes (for both
males and females).">
<caption><em>A test table with merged cells</em></caption>
<tr><th rowspan="2"><th colspan="2">Average
    <th rowspan="2">Red<br>eyes
    <tr><th>height<th>weight
    <tr><th>Males<td>1.9<td>0.003<td>40%
    <tr><th>Females<td>1.7<td>0.002<td>43%
</table>
</alt>
