Johannes is right to point out the potential for annoying redundancy
here, especially if the body text also contains a full
description/explanation of the table.

I'm not sure about Window-Eyes, HAL, or other screen readers, but with
JAWS the user can jump directly to any table on the page by pressing the
letter "t".  If the table has a <caption> element, JAWS speaks the
caption; it will also speak the summary if it's present.  

Pressing the "t" would cause JAWS to bypass the H<x> element in the
example above.

Again, I'm not certain how other screen readers would handle this.

I see your point.

Some people think, that it's better to have a hx element preceding the 
table because they can be jumped to by several ATs. With a need to add a

caption, it would be like

<h2>table caption</h2>
<table>
   <caption>table caption</caption>
   ...
</table>
