How to preserve form submit with custom TableColumns

[Tim Downey]

Hi,

I'm working through the Tapestry Tables examples from John Reynolds
and am stumped on how to preserve the FormTable semantics when
overriding the TableColumns in a TableView component.

When the table is a FormTable, clicks on the column headers will use
javascript to submit the form prior to sorting.  This behavior is
necessary for a form table.  I'd like to override the
TableColumns component, but preserve this submit behavior, but don't
quite see how.

Here's the example:

        <table class="mytable" jwcid="tableView">
          <span jwcid="tableColumns"/>
          <span jwcid="tableRows">
          <span jwcid="[EMAIL PROTECTED]">
             <span jwcid="editableBirthDate"/>
          </span>
          <span jwcid="[EMAIL PROTECTED]">
             <span jwcid="editableWeight"/>
          </span>
              <span jwcid="[EMAIL PROTECTED]:TableValues"/>
      </span>
      <tr>
         <td colspan="7" class="tablepager">
            <span jwcid="[EMAIL PROTECTED]:TableFormPages"/>
         </td>   
      </tr>
      </table>

where tableColumns is defined as:

    <component id="tableColumns" type="contrib:TableColumns">
        <static-binding name="class" value="columnheader"/>
    </component>

How do I specify tableColumns such that it will still perform the form
submit javascript for me?  I didn't see anything like
contrib:TableFormColumns.  Am I missing something?
