Also this is an user agent issue: the user agent should identify the table presence: give an h2 to a table caption means give a second-level title priority.
This is a screen reader (user agent) issue. When u edit a content, is difficoult that a table caption is a title.

    Oggetto: [techs] Table Summary Tests (111, 112, 113, 114, 203)
    
    
    
    How about this:
    
    <table summary="describe structure etc.">
      <caption><h2>table caption</h2></caption>
      ...
    </table>
    
    With this example, there is no on-screen redundancy of the caption text
    as it is given only once.  In Jaws, pressing t will jump to this table,
    but pressing h will move to the caption in the table as well as it will
    be included in the headings list.
    
    I can't remember if putting hx inside caption is invalid or not... 
    
    I agree with the notion that title is problematic as a table attribute
    describing the table as it results in annoying tooltips for some common
    user agents.

    Some people think, that it's better to have a hx element preceding the

    <h2>table caption</h2>

    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.
