如何在html table中给出breakline。？

标签： javascript html css

Image of table我设计了带水平和垂直滚动条的表格。现在问题在于同一个可滚动的有两个表具有相同的数据，但我想在完成第一个表数据后给出中断行。如何给出突破线。这里的意图是我必须显示两个以上具有可滚动的响应边界表。我试过这段代码，但我没有得到突破。

不确定我是否完全理解你要做的事情，但听起来好像你想用colspan创建一个填充表格宽度的单个单元格，所以你可以离开它是空白的，就像这样：

<tr>
  <td colspan="12"></td>
</tr>

然后，您可以在此空白行中添加一个类，以便根据需要设置样式，例如

＆＃13;
＆＃13; 
<!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>
