=cut
#-------------------------------------------------------------------
=head2 definition ( [ additionalTerms ] )
See the super class for additional details.
=head3 additionalTerms
The following additional parameters have been added via this sub class.
=head4 ajaxDataUrl
This is the URL to get the data from, AJAX-style.
=head4 ajaxSaveUrl
This is the URL to send AJAX requests to. If this exists, will send
updates to the table asyncronously.
=head4 ajaxSaveFunc
This is the ?func= to send AJAX requests to.
=head4 ajaxSaveExtras
Any extra name=value pairs needed to save the data successfully
=head4 showEdit
If true, will enable the table for editing. This is only necessary when
displaying the table with getValueAsHtml().
