Add box-shadow to tbody in CSS?

I am trying to recreate this material design table I made in a Photoshop mockup:

enter image description here

I've got everything I want except for a drop shadow. When I apply a drop shadow to the tbody element, it shows in Firefox, but not Chrome or Edge.If I apply a "display: block" style to it as well, it will show. However, this removes the default "display: table-row-group" style, effectively ruining the structure of the table. How can I add a drop shadow without affecting the rest of the layout?



* {
font-family: Roboto, Arial;
}

body {
background: #f8f8f8;
}

table {
border-collapse: collapse;
width: 100%;
}

th {
font-weight: normal;
opacity: .7;
text-align: left;
padding-left: 20px;
padding-bottom: 10px;
}

td {
padding: 20px;
}

tbody tr:nth-child(even) {
background: rgba(128,128,128,.05);
}

tbody {
background: #fff;

/* This doesn't work unless "display: block" is applied, which ruins the structure */
box-shadow: 0 2px 5px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12);
-moz-box-shadow: 0 2px 5px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12);
-webkit-box-shadow: 0 2px 5px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12);
}

.grey {
opacity: .5;
}

.green {
color: #4caf50;
}

<table>
<thead>
<tr>
<th>Name</th>
<th>Date</th>
<th>Grade</th>

<tbody>
<tr>
<td>You</td>

<td class="green">92%</td>

Answer

I spent a few hours on this issue and have finally a working solution that doesn't break the table layout. But now that I think about it flexbox would probably be much simpler...

table {
  position: relative;
}

table:after {
  content: '';
  position: absolute;
  box-shadow: 0 2px 4px 0 rgba(37, 37, 37, 0.2); // your box-shadow
  left: 0;
  right: 0;
  top: 36px; // height of your table header
  bottom: 0;
  z-index: -1;
}
