实用导出：JavaScript （JS）操作web页面导出为Excle示例
?
在日常的开发中，经常会遇到一些报表导出，这里有一个简单的页面导出！
不过有一点，要对IE的ActiveX进行设置，具体的写在源码，文档里了！可以进行下载。
<table id="tableExcel" width="100%" border="1" cellspacing="0" cellpadding="0"> <tr> <td colspan="5" align="center">WEB页面导出为EXCEL示例</td> </tr> <tr> <td>列标题1</td> <td>列标题2</td> <td>列标题3</td> <td>列标题4</td> <td>列标题5</td> </tr> <tr> <td>aaa</td> <td>bbb</td> <td>ccc</td> <td>ddd</td> <td>eee</td> </tr> <tr> <td>AAA</td> <td>BBB</td> <td>CCC</td> <td>DDD</td> <td>EEE</td> </tr> <tr> <td>FFF</td> <td>GGG</td> <td>HHH</td> <td>III</td> <td>JJJ</td> </tr> </table>

按钮：
<input type="button" onclick="javascript:method1('tableExcel');" value="第一种方法导入到EXCEL"> <input type="button" onclick="javascript:method2('tableExcel');" value="第二种方法导入到EXCEL"> <input type="button" onclick="javascript:getXlsFromTbl('tableExcel',null);" value="第三种方法导入到EXCEL"> 以下是三个按钮对应的JS函数：
? 函数1：
