html - 在带有边框空间的表格上放置一个 CSS 边框

Question

我正在使用以下 HTML 和 CSS（参见CodePen）：

<table id="responseTable" style="margin-top:10px;"  >
    <tbody> 
        <tr>
            <td><div></div></td>
            <td><div class="emptyCell"></div></td>
            <td><div class="emptyCell"></div></td>
            <td><div class="emptyCell"></div></td>
        </tr>
        <tr>
            <td>5 Min.</td>
            <td class="third">14</td>
            <td class="third">3</td>
            <td class="third">12</td>
        </tr>
        <tr>
            <td>15 Min.</td>
            <td class="second">2</td>
            <td class="second">12</td>
            <td class="second">12</td>
        </tr>
        <tr>
            <td>&lt; 1 Std.</td>
            <td class="first">2</td>
            <td class="first">5</td>
            <td class="first">12</td>
        </tr>  
        <tr id="labelRow">
            <td> </td>
            <td>Total</td>
            <td>AD</td>
            <td>VKF</td>
        </tr> 
    </tbody>
    <tfoot>
        <tr id="testsRow">
            <td style="border-top: 2px solid black;">tests</td>
            <td style="border-top: 2px solid black;">5</td>
            <td style="border-top: 2px solid black;">12</td>
            <td style="border-top: 2px solid black;">12</td>
        </tr>
    </tfoot>
</table>

body, html {
    width:100%;
    height:100%;
    margin:0;
    padding:0; 
    font-family:arial;
}

#responseTable {
    border-collapse:separate; 
    border-spacing: 20px 0px;
}

th, td {
    padding: 0;
}

td{
    text-align:center;  
}

tr{
     height:50px;
}

.emptyCell
{
    height:50px;
    border-radius: 10%;
    border-top: gray dashed 2px;
    border-left: gray dashed 2px;
    border-right: gray dashed 2px;

    border-bottom: gray dashed 2px;
    /* margin-bottom:-5px; */

    background-Color:white;
}

tr td:nth-of-type(1) {
    width:50px; 

}
tr td:nth-of-type(2)
{
    margin-left:20px;
    width:100px;    
}

tr td:nth-of-type(1)
{
    width:100px;   
}

tr td:nth-of-type(1) ~ td
{
    color:white; 
    border-bottom:white solid 1px;
}

tr td:nth-of-type(2) ~ td
{
    width:40px;    
}

#testsRow td{
  background-color:#99cc66;
  color:#000;
}

#labelRow td{
  background-color:white;
  color:#000;
}

.first {    
background-color: #91B219;
}

.second {    
background-color: #1F8A70;
}

.third {    
background-color: #004358;
}

...在表格单元格上设置顶部边框。但由于我使用border-spacing的会导致单元格之间出现间隙，因此顶部边框不适用于“间隙”，因此我无法在#testsRow.

我也考虑过标签tfoot是否有帮助，但垂直边框空间仍然存在......

我还考虑在一个额外的表格中制作摘要页脚，这样当我使用虚拟间隙/空列时，它们只为一行创建，而不是在我将此类列用于顶部图表表时创建的所有行。

或者是否可以只在tbody而不是tfoot比我至少只有一张桌子上使用边框间距。

或者你有更好的主意？

我无法在此处发布 html 代码。顺便说一句，我已经编辑了小提琴。这次甚至分叉了它，以避免像以前一样被覆盖。

HTML

    </tr>
  <tr>
    <td>5 Min.</td>
    <td class="third">14</td>
    <td class="third">3</td>
