CSS 表格(table)
CSS 表格
使用CSS可以大大提高HTML表格的外观。
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:
<!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>数学</th> <th>语文</th> </tr> <tr> <td>90</td> <td>98</td> </tr> <tr> <td>95</td> <td>94</td> </tr> </table> </body> </html>

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:
<!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>数学</th> <th>语文</th> </tr> <tr> <td>90</td> <td>98</td> </tr> <tr> <td>95</td> <td>94</td> </tr> </table> </body> </html>

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:
<!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>

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>
