Js实现动态添加删除Table行示例

<table cellpadding="0" cellspacing="0" border="1" style="margin:auto; width:96%;" id="LearnInfoItem"> <tr > <td colspan="8" bgcolor="#96E0E2" style="height:30px;" ><h3 style="text-align:center; margin:0;">主要学习简历</h3></td> </tr> <tr id="tr1"> <td class="tdStyle2">起讫时间 </td> <td class="tdStyle2">毕业院校</td> <td class="tdStyle2">所学专业</td> <td class="tdStyle2">学制</td> <td class="tdStyle2">学位</td> <td class="tdStyle2">学习方式</td> <td class="tdStyle2">文化程度</td> <td class="tdStyle2"> <input type="button" name="LearnAdd" value="添加" onclick="LearnAddSignRow()" /> <input name=‘LearnTRLastIndex‘ type=‘hidden‘ id=‘LearnTRLastIndex‘ value="1" /> </td> </tr> </table>
