一、 直接拷贝整个表格到EXCEL中二、 通过遍历表格，给EXCEL中相应的单元格赋值。三、 把表格中的内容提取出来，利用IE的另存为csv的格式。各方法的好处：1 直接拷贝表格，能够保留表格中的原有的格式，比如，列，行的合并，对齐方式，底色等等，2 通过遍历表格，比较灵活，可以遍历表格某些需要部分的内容。3 利用IE的另存为，不用创建ActiveXObject对象，可以处理表格合并方面的问题。各方法的缺点：1 可能d出脚本错误：Automation不能创建对象。解决方法：启用IE安全设置中的：对没有标记为安全的ActiveX控件进行初始化和脚本运行。由于整个表格复制到EXCEL中，给表格加个标题，并加入到EXCEL中可能会遇到麻烦。解决方法：首先在表格中加入第一行<tr><td colspan="x" align="center">&</td></tr>X，表示整个表格的列数，复制完整个表格后,加如下代码，oSheet为当前活动的sheetoSheetRange(oSheetCells(1, 1), oSheetCells(1, x))value = "表格标题";//设置标题oSheetRows(1)FontSize = 16; //设置文字大小oSheetRows(1)FontName = "宋体";//设置文字字体注：以下属性我没用着，可能有用，也可能会报错oSheetRange(oSheetCells(1,1), oSheetCells(1,14))mergecells=true; //合并单元格oSheetRange(oSheetCells(1,1), oSheetCells(1,14))InteriorColorIndex=6;//设置底色oSheetRange(oSheetCells(1,1), oSheetCells(1,14))FontColorIndex=5;//设置字体色oSheetRows(1)RowHeight=20; //设置列高oSheetCells(iRow,iCol)Halignment=’2’//设置字体居中2 可能d出脚本错误：Automation不能创建对象（解决方法如上）。表格内容写入到EXCEL中无表格线（未解决）且有单元格合并时会有问题，解决方法：合并单元格后再写数据。oSheetRange(oSheetCells(1,1), oSheetCells(1,14))mergecells=true; //合并单元格3 表格内容写入到EXCEL中无表格线（未解决）表格格式复杂时，会有问题，（rowspan>1 or colspan>1）,解决方法：一般都是表头格式比较复杂，可先把表头写死，然后再循环写其他数据。代码如下：<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 40 Transitional//EN"><HTML><HEAD><TITLE> New Document </TITLE>

1、JS获取表格的简便方法：获取tbody:tBodies 获取thead:tHead 获取tfoot:tFoot 获取行tr:rows 获取列td:cells
使用实例： oTabletBodies[0] oTabletHead[0] oTabletFoot[0] oTablerows[1] oTablecells[1]
2、遍历
var oTable=documentgetElementById("表格id");
oTabletBodies[0]可以看成是rows和cells组成的二维数组，用两个for循环嵌套遍历一下就可以了
