如何在col html标签中应用框阴影？

Question

[这里，我有一个由树枝中的for循环创建的表，我想将其应用于shaow。就是说，当班上的定居者“被选中”时，他欺骗了他，使用了盒子阴影。但这不起作用：/

我的树枝代码：

{% set title= "Nos offres Minecraft - DataHosting" %}
{% set description = "Venez découvrir nos offres minecraft 100% gratuites à vie et performante. Vous n'avez pas besoin de débourser 1 centime !" %}
{% set org_url = url('offre_minecraft') %}

{% extends "site/baseSite.html.twig" %}

{% block content %}
    <div class="table-responsive">
    <table class="table table-striped-col table-light">

            <col>
            {% for product in list_product %}
            <col {{ (app.request.get("offre") is defined and app.request.get("offre") == product.id) ? 'class="seleted_offre"' : "" }}>

                </div>
            </div>
        </div>
    </div>
    {% endfor %}
{% endblock %}

{% block javascripts %}
<script type="text/javascript">
    //Checkout ?
    function addCart(url, index) {
        fetch(url);
        $("#continue_or_not" + index).modal("show");
    }
</script>
{% endblock %}

唯一可以准备的代码是这样：

td:first-child,th:first-child{
  box-shadow: -15px 0 15px -15px inset;
}

但是它仅逐行显示，而且不是很漂亮。

感谢您的帮助！

您可以使用此网站制作盒子阴影。

 -webkit-box-shadow: 10px 10px 5px 0px rgba(0,0,0,0.75);
 -moz-box-shadow: 10px 10px 5px 0px rgba(0,0,0,0.75);
 box-shadow: 10px 10px 5px 0px rgba(0,0,0,0.75);
