Image of table我设计了带有水平和垂直滚动条的表格。现在这里的问题是在同一个滚动中有两个表具有相同的数据但是我想在完成第一个表数据后给出断行。如何给分界线。这里的目的是我必须显示两个以上的可滚动的响应式边框表格。我试过这段代码，但我没有得到断线。
<!DOCTYPE html>
<html>
<head>
<style>
table {
border-collapse: collapse;
border-spacing: 0;
width: 100%;
border: 1px solid #ddd;
}
th, td {
text-align: left;
padding: 8px;
}
tr:nth-child(even){background-color: #f2f2f2}
</style>

不确定我是否完全理解你想要做什么，但听起来你可能想使用 colspan 创建一个填充表格宽度的单元格，这样你就可以留空，像这样:
<tr>
<td colspan="12"></td>
</tr>
然后您可以将一个类添加到此空白行以根据需要设置样式，例如
<!DOCTYPE html>
<html>
<head>
<style>
table {
border-collapse: collapse;
border-spacing: 0;
width: 100%;
border: 1px solid #ddd;
border-bottom: 1px solid black;
}
th, td {
text-align: left;
padding: 8px;
}
th:first-child, td:first-child {
border-left: 1px solid black;
}
th:last-child, td:last-child {
border-right: 1px solid black;
}
tr:nth-child(even){background-color: #f2f2f2}
.divider td {
background: black;
padding: 5px;
color: white;
text-align: center;
border: 1px solid black;
}
</style>
</head>
<body>
<div style="overflow:auto;">
<table>
<tr class="divider">
<td colspan="12">Heading</td>

<th>First Name</th>
