Getting this error
dataTables.colReorder.js:856 Uncaught TypeError: Cannot read property '_ColReorder_iOrigCol' of undefined

DataTables 1.10.11 (tried changing my version to DataTables 1.10.12, no change).
ColReorder 1.3.2

If i comment out " colReorder: true, " below the error goes away.

To my cshtml page I added

colReorder.dataTables.css by Html.CssStyles().AddStyle(Url.Content("~/js/ColReorder/colReorder.dataTables.css"));
jquery.dataTables.js // was just using jquery.dataTables.min.js before
dataTables.colReorder.js by @Html.AddScriptFile(Url.Content("~/js/ColReorder/dataTables.colReorder.js"))

in my cshtml page I have this:

  @model HelpDesk.Models.PatientListModel

  @{
      ViewBag.Title = "Patient Management";
      //Html.CssStyles().AddStyle(Url.Content("~/js/jquery.datetimepicker.css"));
      Html.CssStyles().AddStyle(Url.Content("~/js/jquery-ui-1.8.18.custom.css"));
      Html.CssStyles().AddStyle(Url.Content("~/js/jquery.dataTables.min.css"));
      Html.CssStyles().AddStyle(Url.Content("~/js/ColReorder/colReorder.dataTables.css"));
