html - JQuery Sortable bootstrap table -

-

i'm trying implement jquery sortable bootstrap 3 table. works fine, when drag row position want it's not under cursor stays pixels @ top, makes hard see dragging.

i'm not sure whether has stylesheet or version of jquery.

html

<table class="table table-bordered table-striped" id="sortable">     <thead>         <tr>             <th>                 title             </th>             <th>                 description             </th>         </tr>     </thead>     <tbody>         <tr data-item-id=3 class="item">             <td>                 voynich manuscript             </td>             <td>                 <a class="btn btn-default pull-right" href="/things/3">show</a>             </td>         </tr>         <tr data-item-id=1 class="item">             <td>                 roman dodecahedra             </td>             <td>                 <a class="btn btn-default pull-right" href="/things/1">show</a>             </td>         </tr>         <tr data-item-id=2 class="item">             <td>                 phaistos disc             </td>             <td>                 <a class="btn btn-default pull-right" href="/things/2">show</a>             </td>         </tr>     </tbody> </table>

js

 var cells, desired_width, table_width;  table_width = $('#sortable').width();  cells = $('.table').find('tr')[0].cells.length;  desired_width = table_width / cells + 'px';  $('.table td').css('width', desired_width);  $('#sortable').sortable({      axis: 'y',      items: '.item',      cursor: 'move',      tolerance: 'pointer',      sort: function(e, ui) {          return ui.item.addclass('active-item-shadow');      },      stop: function(e, ui) {          ui.item.removeclass('active-item-shadow');          return ui.item.children('td').effect('highlight', {}, 1000);      },      update: function(e, ui) {          var item_id, position;          item_id = ui.item.data('item-id');          console.log(item_id);          position = ui.item.index();          console.log(position);          return $.ajax({              type: 'post',              url: '/things/update_row_order',              datatype: 'json',              data: {                  thing: {                      thing_id: item_id,                      row_order_position: position                  }              }          });      }  });
