<table border="1" cellpadding="5">
    <thead>
        <tr>
            @if (Model != null)
            {
                foreach (System.Data.DataColumn col in Model.Columns)
                {
                    <th>@col.Caption</th>
                }

        {
            foreach (System.Data.DataRow row in Model.Rows)
            {
                <tr>
                    @foreach (var cell in row.ItemArray)
                    {
                        <td>@cell.ToString()</td>
