Can stickyHeader apply to <caption> as well?

[cautionbug]

In trying to make my data tables more semantically correct, i want to avoid placing a table title inside a cell, so i've been using the <caption> tag as (i think) it was intended.

However, stickyHeaders doesn't seem to apply to it, even if i add it to the selectorHeaders string like so:

$('table').tablesorter({
  selectorHeaders: '> caption, > thead th',
  sortMultiSortKey: 'ctrlKey',
  textExtraction  : 'complex',
  widgets: ['stickyHeaders', 'uitheme'],
  widgetOptions: {
    stickyHeaders: 'tablesorter-stickyHeader',
    uitheme: ['ui-icon-triangle-2-n-s', 'ui-icon-triangle-1-s', 'ui-icon-triangle-1-n']
  }
});

The headers stick, which is great. i'd just like to provide my users with a reference point of which table they're looking at (they demand several to clutter up the same page, go figure).

Any thoughts?

The sticky headers widget doesn't include the caption, but I'll look into adding this in version 2.4. Thanks for the suggestion.
