表头中的超链接未呈现

Question

我正在尝试将超链接/动作链接放在我的表格标题中，以便进行排序，但出于某种原因，它们不会呈现。

知道为什么它没有正确渲染？在下面的代码中，您看到第一个表头是Actionlink。标题呈现为空。我检查了元素，它确实显得空洞。

代码：

@model PagedList.IPagedList<FitnerWebRole.ViewModels.CenterVM>
@using FitnerWebRole.Models
@using IdealDatabase

@{
    ViewBag.Title = "Centers";
}
@using (IdealDb db = new IdealDb(ApiConfig.AppName, ApiConfig.DbServer, ApiConfig.DbUser, ApiConfig.DbPassword))
{
    <div class="container adminContainer event">
        <p>
            @Html.ActionLink("Create New", "Create", null, new { @class = "btn btn-success" })
        </p>
        @Html.PagedListPager(Model, page => Url.Action("Index", new { page }), PagedList.Mvc.PagedListRenderOptions.Minimal)
        <table id="centerTable" class="table">
            <thead>
                <tr>
                    <th>
                        @Html.ActionLink("Name", "Index", new { sortOrder = "name", currentSort = "name" })
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.FirstOrDefault().Address)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.FirstOrDefault().ChainId)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.FirstOrDefault().CityId)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.FirstOrDefault().LangId)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.FirstOrDefault().Lat)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.FirstOrDefault().Lon)
                    </th>
                    <th></th>
                </tr>
            </thead>
            @foreach (var item in Model)
            {
                <tr>

        </table>

        @Html.PagedListPager(Model, page => Url.Action("Index", new { page }))
