使用CSS可以大大提高HTML表格的外观。例：
| Company | Contact | Country |
|---|---|---|
| Alfreds Futterkiste | Maria Anders | Germany |
| Berglunds snabbköp | Christina Berglund | Sweden |
| Centro comercial Moctezuma | Francisco Chang | Mexico |
| Ernst Handel | Roland Mendel | Austria |
| Island Trading | Helen Bennett | UK |
| Königlich Essen | Philip Cramer | Germany |
| Laughing Bacchus Winecellars | Yoshi Tannamuri | Canada |
| Magazzini Alimentari Riuniti | Giovanni Rovelli | Italy |
| North/South | Simon Crowther | UK |
| Paris spécialités | Marie Bertrand | France |
| The Big Cheese | Liz Nixon | USA |
| Vaffeljernet | Palle Ibsen | Denmark |
指定CSS表格边框，使用border属性。
下面的例子指定了一个表格的Th和TD元素的黑色边框：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网(php.cn)</title>
<style>
table,th,td
{
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>
</body>
</html>点击 "运行实例" 按钮查看在线实例
请注意，在上面的例子中的表格有双边框。这是因为表和th/ td元素有独立的边界。
为了显示一个表的单个边框，使用 border-collapse属性。
border-collapse 属性设置表格的边框是否被折叠成一个单一的边框或隔开：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网(php.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> 如果没有指定 !DOCTYPE border-collapse 属性在 IE8 及更早 IE 版本中是不起作用的。</p>
</body>
</html>点击 "运行实例" 按钮查看在线实例
Width和height属性定义表格的宽度和高度。
下面的例子是设置100％的宽度，50像素的th元素的高度的表格：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网(php.cn)</title>
<style>
table,td,th
{
border:1px solid black;
}
table
{
width:100%;
}
th
{
height:50px;
}
</style>
</head>
<body>
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Savings</th>
</tr>
<tr>
<td>Peter</td>
<td>Griffin</td>
<td>$100</td>
</tr>
<tr>
<td>Lois</td>
<td>Griffin</td>
<td>$150</td>
</tr>
<tr>
<td>Joe</td>
<td>Swanson</td>
<td>$300</td>
</tr>
<tr>
<td>Cleveland</td>
<td>Brown</td>
<td>$250</td>
</tr>
</table>
</body>
</html>点击 "运行实例" 按钮查看在线实例
表格中的文本对齐和垂直对齐属性。
text-align属性设置水平对齐方式，像左，右，或中心：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网(php.cn)</title>
<style>
table,td,th
{
border:1px solid black;
}
td
{
text-align:right;
}
</style>
</head>
<body>
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Savings</th>
</tr>
<tr>
<td>Peter</td>
<td>Griffin</td>
<td>$100</td>
</tr>
<tr>
<td>Lois</td>
<td>Griffin</td>
<td>$150</td>
</tr>
<tr>
<td>Joe</td>
<td>Swanson</td>
<td>$300</td>
</tr>
<tr>
<td>Cleveland</td>
<td>Brown</td>
<td>$250</td>
</tr>
</table>
</body>
</html>点击 "运行实例" 按钮查看在线实例
垂直对齐属性设置垂直对齐，比如顶部，底部或中间：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网(php.cn)</title>
<style>
table, td, th
{
border:1px solid black;
}
td
{
height:50px;
vertical-align:bottom;
}
</style>
</head>
<body>
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Savings</th>
</tr>
<tr>
<td>Peter</td>
<td>Griffin</td>
<td>$100</td>
</tr>
<tr>
<td>Lois</td>
<td>Griffin</td>
<td>$150</td>
</tr>
<tr>
<td>Joe</td>
<td>Swanson</td>
<td>$300</td>
</tr>
<tr>
<td>Cleveland</td>
<td>Brown</td>
<td>$250</td>
</tr>
</table>
</body>
</html>点击 "运行实例" 按钮查看在线实例
如果在表的内容中控制空格之间的边框，应使用td和th元素的填充属性：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网(php.cn)</title>
<style>
table, td, th
{
border:1px solid black;
}
td
{
padding:15px;
}
</style>
</head>
<body>
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Savings</th>
</tr>
<tr>
<td>Peter</td>
<td>Griffin</td>
<td>$100</td>
</tr>
<tr>
<td>Lois</td>
<td>Griffin</td>
<td>$150</td>
</tr>
<tr>
<td>Joe</td>
<td>Swanson</td>
<td>$300</td>
</tr>
<tr>
<td>Cleveland</td>
<td>Brown</td>
<td>$250</td>
</tr>
</table>
</body>
</html>点击 "运行实例" 按钮查看在线实例
下面的例子指定边框的颜色，和th元素的文本和背景颜色：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网(php.cn)</title>
<style>
table, td, th
{
border:1px solid green;
}
th
{
background-color:green;
color:white;
}
</style>
</head>
<body>
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Savings</th>
</tr>
<tr>
<td>Peter</td>
<td>Griffin</td>
<td>$100</td>
</tr>
<tr>
<td>Lois</td>
<td>Griffin</td>
<td>$150</td>
</tr>
<tr>
<td>Joe</td>
<td>Swanson</td>
<td>$300</td>
</tr>
<tr>
<td>Cleveland</td>
<td>Brown</td>
<td>$250</td>
</tr>
</table>
