本文實例為大家分享了JavaScript實現HTML表格排序功能，供大家參考，具體內容如下
HTML代碼：
<table cellpadding="0" id="table"> <tr> <td>click me</td> <td>click me</td> <td>click me</td> <td>click me</td> </tr> <tr> <td> <span id="bfn_la_bac.usa">15.43</span> </td> <td>700</td> <td>1.220</td> <td>阿</td> </tr> <tr> <td> <span id="bfn_la_c.usa">7.05</span> </td> <td>4</td> <td>3,000</td> <td>炳</td> </tr> <tr> <td> <span id="bfn_la_jpm.usa">30.62</span> </td> <td>30</td> <td>2,558,800</td> <td>和</td> </tr> <tr> <td> <span id="bfn_la_axp.usa">22.30</span> </td> <td>5</td> <td>6</td> <td>瞎</td> </tr> <tr> <td> <span id="bfn_la_mrk.usa">26.31</span> </td> <td>0.6</td> <td>5</td> <td>-</td> </tr> <tr> <td> <span id="bfn_la_pg.usa">63.16</span> </td> <td>7</td> <td>4</td> <td>子</td> </tr> </table>
