Using DataTables Plugin in Razor View - Cannot set properties of undefined (setting '_DT

I am using a asp.net mvc web app. I have created a table and now I am wanting to use the plugin in

But am getting this... so I am missing the look of the datatable plugin and the following Error.

Cannot set properties of undefined (setting '_DT_CellIndex')

my view:

@model List<Fright>


@{
    ViewData["Title"] = "Home Page";
     var result = Model.GroupBy(gb => gb.Value);
}

            <tbody>
                @foreach (var item in result)
                {
                    var url = "/frightSummary/SummaryIndex?id="   item.Key;
                    <tr>
                        <td>

                        </td>
                    </tr>

                }

CodePudding user response：

Your problem is a mismatch in the number of <td> </td>. You are just rendering 1 <td> in foreach loop but you have two <th></th> in the table header

@model List<Fright>

    ViewData["Title"] = "Home Page";
     var result = Model.GroupBy(gb => gb.Value);
