                            ## border-collapse 屬性
border-collapse 屬性設置表格的邊框是否被合并為一個單一的邊框，還是象在標準的 HTML 中那樣分開顯示。
JavaScript 語法:object&nbsp;object.style.borderCollapse="collapse"

## [在線實例](https://www.w3cschool.cn/tryrun/showhtml/trycss_table_border-collapse)
```
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"> 
<title>W3Cschool教程(w3cschool.cn)</title>
<style>
table {
    border-collapse: collapse;
}

table, td, th {
    border: 1px solid black;
}
</style>
</head>
<body>

<table>
  <tr>
    <th>Firstname</th>
    <th>Lastname</th>
  </tr>
  <tr>
    <td>Peter</td>
    <td>Griffin</td>
  </tr>
  <tr>
    <td>Lois</td>
    <td>Griffin</td>
  </tr>
</table>

<p><b>注意;</b> 如果沒有指定 !DOCTYPE  border-collapse 屬性在 IE8 及更早 IE 版本中是不起作用的。</p>
