将左列添加到 MVC Net Core 项目模板视图，该视图会随着用户向下滚动而消失

Question

我创建了一个 MVC Core Net 项目模板。我从脚手架创建了一个产品索引表。

如何在左侧添加一列，如红框所示？这不是侧面导航栏，而只是该页面特定类别左侧的一列。当用户向下滚动时，左列应该消失。它不应该被修复。

Column Left Image

@model IPagedList<ElectronicsStore.Models.Product>
@{
    ViewBag.Title = "Products";
    int counter = 0;
}
@using X.PagedList;
@using X.PagedList.Mvc.Core;


<table class="table" >
    <thead>
        <tr>
            <th class="col3">
                @*@Html.DisplayNameFor(model => model.FirstOrDefault().ProductName)*@
            </th>
            <th class="col4">
                @*@Html.DisplayNameFor(model => model.FirstOrDefault().ProductDescription)*@
            </th>
            <th></th>
        </tr>
    </thead>

    <tbody>
        @foreach (var item in ViewBag.OnePageOfProducts)
        {
        <tr>
            <td class="col3">

                    <a href='@Url.Action("Details","Products" , new { id=item.ProductId })'>
                        <img src="~/images/@(item.ImageLocation)"  data-holder-rendered="true" >
                    </a>
                    <div class="caption">

            </td>
            @*<td class="col3">
                <img src="~/images/@(item.ImageLocation)" data-holder-rendered="true" />

            </td>*@
            <td class="col4">

                    <br />
                    @item.ProductName

            </td>
        </tr>
        }
    </tbody>
</table>
