表頭固定的前提下表格添加縱向滾動條

表格 動態 overflow borde col float 技術 上下 height
有時候在不分頁且數據多的時候就需要滾動條，或者說是下拉加載的時候也需要滾動條，但是希望在滾動的時候數據的表頭固定便於理解表體。
如下:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style> table { border-collapse: collapse; width: 100%; text-align: left; border:1px solid #000; } td,th{ border:1px solid #000; } tbody{ display: block; overflow-x: hidden; overflow-y: auto; height: 100px; } thead,tbody tr{ display: table; width: 100%; table-layout: fixed; word-break: break-all; } table thead{ width: calc(100% - 17px); }</style> </head> <body> <div style="height: 250px;"></div> <div style="height: 250px;"></div> <table cellspacing="0" cellpadding="0"> <thead> <th>表頭1</th> <th>表頭2</th> <th>表頭3</th> <th>表頭4</th> <th>表頭5</th> </thead> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> </table> </body> </html>
結果:
有時候需要根據屏幕可用高度來動態設置表格的高度和表頭的寬度:(也就是可用寬度不足以顯示內容的時候將tbody定高，並且將thead的寬度減去滾動條的寬度使得上下對齊)
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style> table { border-collapse: collapse; width: 100%; text-align: left; border: 1px solid #000; } td, th { border: 1px solid #000; } tbody { display: block; overflow-x: hidden; overflow-y: auto; } thead, tbody tr { display: table; width: 100%; table-layout: fixed; word-break: break-all; } </style> <script src="../js/jquery-1.8.3.min.js"></script> </head> <body> <div style="height: 250px;"></div> <div style="height: 250px;"></div> <div id="tebleDiv"> <table cellspacing="0" cellpadding="0"> <thead> <th>表頭1</th> <th>表頭2</th> <th>表頭3</th> <th>表頭4</th> <th>表頭5</th> </thead> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> </table> </div> </body> </html> <script> $(function() { var windowHeight = $(window).height(); //窗口可用高度 var topValue = $("#tebleDiv").offset().top; var tebleDivHeight = $("#tebleDiv").height(); if (parseFloat(topValue) + parseFloat(tebleDivHeight) + 180 < parseFloat(windowHeight)) { return; } var realHeight = windowHeight - topValue -50; $("table tbody").css("height", realHeight + "px"); $("table thead").css("width", ($("table thead").width() - 18) + "px"); }); </script>
