Sortable table with expandable rows

I am new to jquery / rails and I am having problems using .sortable (). I have extensible lines, and I can’t get the correct code to have a hidden line, that is, a child line, stick to the visible, that is, the parent line. Corresponding JS code:

(function($){
    $.fn.jSortable = function(){


    var element = this;

    var fixHelper = function(e, ui) {
        ui.children().each(function(){
            $(this).width($(this).width());
        });
        return ui;
    };

    $(element).sortable({
        helper: fixHelper,
        axis: "y",
        cursor: "move",
        items: "tr.odd2",
        distance: "30"

    });
    $(element).disableSelection();
};

})(jQuery);

The parent row has the odd2 class, and the child row is the child.

What is the correct way to lock two lines when applying .sortable ()?

I am currently using rails 3.1.1 with jquery-rails 1.0.19

EDIT:

Here is the relevant html

<table id="sortableTable">
  <tr class= 'headings'>
        <th><%= sortable "number" %></th>
        <th><%= sortable "customer_id" %></th>
        <th><%= sortable "priority" %></th>
        <th><%= sortable "quantity" %></th>
        <th><%= sortable "due_date" %></th>
        <th></th>
  </tr>

<% @jobs.each do |job| %>
  <tr class= "odd2">
    <td><%= job.number %></td>
    <td><%= job.customer %></td>
    <td><%= job.priority %></td>
    <td><%= job.quantity %></td>
    <td><%= job.due_date %></td>
    <td><%= button 'Edit', edit_job_path(job) %></td>
  </tr>

  <tr class= "child">
    <td><%= job.job_items %></td>
  </tr>
 <% end %>
</table>

<%= javascript_tag do %>
$(document).ready(function(){
    $('#sortableTable tbody').jSortable();
});

<% end %>

EDIT 2: I upgraded my application to Rails 3.2.1 using jquery-rails 2.0.0

EDIT 3: Since no one has provided a solution for a table tag instead of a div, and I still need to find something that relates to the table, I have to switch to a div.
