VistasUsing DataTables Plugin in Razor View - Cannot set properties of undefined (setting '_DT_CellIndex') Error
I am using a asp.net mvc web app. I have created a table and now I am wanting to use the plugin in datatables. I saw you only needed 3 lines of code to make this work. I attempted to do exactly what it required in order for it to work and give me the desired datatable, but it does not give me the table I am expecting. I even went to examples -> HTML (DOM) source data -> and under Javascript tab I entered the lines required.
Is there something I am doing incorrect here with the script tags or is the plug in just not working? I do not have the files downloaded and imported to my project.
Expecting a standard look like this 
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);
}
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-3.5.1.js"></script>
<link href="//cdn.datatables.net/1.11.2/css/jquery.dataTables.min.css" rel="stylesheet"/>
<script type="text/javascript" charset="utf8" src="//cdn.datatables.net/1.11.2/js/jquery.dataTables.min.js" defer></script>
<script>
$(document).ready(function () {
$('#homeTable').DataTable();
});
</script>
</head>
<body>
<div>
<table id="homeTable" class="display" style="width:100%">
<thead>
<tr>
<th>Value</th>
<th>Option</th>
</tr>
</thead>
<tbody>
@foreach (var item in result)
{
var url = "/frightSummary/SummaryIndex?id=" + item.Key;
<tr>
<td>
<a href=@url>@item.Key</a>
</td>
</tr>
}
</tbody>
</table>
</div>
</body>
</html>

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);
}
