表格边框
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：
<style> table,th,td { border:1px solid black; } </style> <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>
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。
折叠边框
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：
<style> table { border-collapse: collapse; } table, td, th { border: 1px solid black; } </style> <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>
表格宽度和高度
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：
<style> table,td,th { border:1px solid black; } table { width:100%; } th { height:50px; } </style> <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>
表格文字对齐
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，向左，右，或中心：
<style> table,td,th { border:1px solid black; } td { text-align:right; } </style> <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>
垂直对齐属性设置垂直对齐，比如顶部，底部或中间：
<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>
表格填充
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
<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>
表格颜色
下面的例子指定边框的颜色，和th元素的文本和背景颜色：
<style> table, td, th { border:1px solid green; } th { background-color:green; color:white; } </style> <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>
