ASP.NETJSP_Jsp中的table多表头导出excel文件具体实现，首先引入两份JS:copyhtmltoexcel.js
function onhtmlToExcel(elTableOut,elDiv){
//elTalbeOut 这个为导出内容的外层表格，主要是设置border之类的样式，elDiv则是整个导出的html部分
elDivStrBak = "";
*/
//过滤elDiv内容
myExcelCell.HorizontalAlignment = this.textAlign;
} elDivStr = replaceHtml(elDivStr,"<A",">");
for (c = 0; c < obj[tabNum].rows(z).cells.length; c++) {
TableToExcel.prototype.setTableBorder = function (excelBorder) {
};
var elDivStr = elDiv.innerHTML;
var tb = new TableToExcel(tableID);
this.backGround = excelColor;
this.fontStyle = excelFont;
myWorksheet = null;
* var tb = new TableToExcel('demoTable');
* tb.setFontColor(6); //一般情况不用设置
//开始构件模拟表格
}; }} var jXls, myWorkbook, myWorksheet, myHTMLTableCell, myExcelCell, myExcelCell2;
while(repStrIndex != -1){
myWorksheet.Rows.RowHeight = this.rowHeight ; readRow = z + 1;
for (col = readCol; col <= myCellColSpan + readCol - 1; col++) {
return false;
myExcelCell.wrapText = this.lineWrap;
oSheet.Columns("D:D").Select
myExcelCell.Font.ColorIndex = this.fontColor;
* tb.setFontSize(10); //推荐取值10
* 版本：1.0
var elDiv = document.getElementById("elDiv");
myWorksheet.Range(myExcelCell, myExcelCell2).Borders(4).Weight = this.tableBorder ;
this.tableBorder = excelBorder ;
if (myCellColSpan * myCellRowSpan > 1) {
var oXL = new ActiveXObject("Excel.Application")
}
TableToExcel.prototype.setBackGround = function (excelColor) {
totalCol = totalCol + myCellColSpan;
myWorksheet.Columns.ColumnWidth = this.columnWidth;
replacedStrF = replacedStr.substring(0,repStrIndex);
myWorksheet.Range(myExcelCell, myExcelCell2).Borders(1).Weight = this.tableBorder ;
myExcelCell = myWorksheet.Cells(readRow, readCol);
readCol = readCol + 1;
*/
}
myCellColSpan = myHTMLTableCell.colSpan;
this.fontColor = 1; //字体颜色：黑色
alert(e.description)
var obj = document.all.tags("table");
* 如果设置了单元格自适应，则设置单元格宽度无效
}
myWorksheet.Range(myExcelCell, myExcelCell2).Borders(3).Weight = this.tableBorder ;
};
myWorkbook.Worksheets(3).Delete();
this.columnWidth = -1; //列宽
TableToExcel.prototype.setFontStyle = function (excelFont) {
myExcelCell.Interior.ColorIndex = this.backGround;
myExcelCell.Font.Size = this.fontSize;
excelTable[i] = new Array();
myHTMLTableCell = obj[tabNum].rows(z).cells(c);
if(this.tableBorder != -1){
TableToExcel.prototype.isLineWrap = function (lineWrap) {
repStrIndex = replacedStr.indexOf(repStr);
* 详细的属性、方法引用说明参见：Excel的Microsoft Excel Visual Basic参考
if (lineWrap == false || lineWrap == true) {
* 说明：
"工具 → Internet选项 → 安全 → 自定义级别 → ActiveX控件和插件 \n\n" +
myExcelCell.Borders(1).Weight = this.tableBorder ;
myWorksheet = myWorkbook.ActiveSheet;
function replaceHtml(replacedStr,repStr,endStr){
首先引入两份JS:copyhtmltoexcel.js以及 tableToExcel.js
* 示范：
* 时间：2006-08-09
//返回格式变换以前的内容
myCellColSpan = myHTMLTableCell.colSpan;
break;
this.rowHeight = -1; //行高
readCol = 1;
jXls = null;
}
* 功能：HTML中Table对象转换为Excel通用对象.
*
}
this.fontSize = excelFontSize;
* tb.setTableBorder(2); //推荐取值2
oRangeRef.moveToElementText( elDiv );
/*
try{
excelTable[i][t] = false;
return replacedStr;
this.textAlign = textAlign;
* tb.isLineWrap(false);
tb.isLineWrap(false);
elDivStr = "";
for (i = 0; i <= totalRow; i++) {
var excelTable = new Array();
this.fontSize = 10; //字体大小
* 默认转换实现函数，如果需要其他功能，需自行扩展
oSheet.Paste();
for (row = readRow; row <= myCellRowSpan + readRow - 1; row++) {
var elDivStrBak = elDiv.innerHTML;
复制代码 代码如下:
}* 作者：Jeva
readCol = y;
try {
//文件转换主函数
tb.isAutoFit(true);
"\n\n如果您确信您的电脑中已经安装了Excel，"+
if(this.autoFit == true)
* tableID : HTML中Table对象id属性值
this.fontColor = excelColor;
oRangeRef.execCommand("Copy");
在JSP页面中写JS方法
alert("无法启动Excel!\n\n" + e.message +
}
//生成Excel
}; function onTableToExcel(){
myExcelCell.Font.Name = this.fontStyle;
"那么请调整IE的安全级别。\n\n具体操作：\n\n"+
replacedStrB = replacedStrB.substring(replacedStrB.indexOf(endStr)+1,replacedStrB.length);
var myCellColSpan, myCellRowSpan; myExcelCell.Interior.ColorIndex = this.backGround;
* 合并Excel中的单元格，客户端需要安装有Excel
TableToExcel.prototype.setTextAlign = function (textAlign) {
jXls.DisplayAlerts = false;
myExcelCell.Font.Name = this.fontStyle;
复制代码 代码如下:
}//搜索需要转换的Table对象，获取对应行、列数
myExcelCell.wrapText = this.lineWrap;
if(autoFit == true || autoFit == false)

tb.setFontStyle("Courier New");
myWorkbook = null;
if(this.columnWidth != -1)
this.autoFit = false; //是否自适应宽度
var replacedStrB = "";
var oSheet = oWB.ActiveSheet ;
myWorksheet.Columns.ColumnWidth = 7;
} else {
//设置导出前的数据，为导出后返回格式而设置
//设置table的border=1，这样到excel中就有表格线 ps:感谢双面提醒
} for (x = 0; x < obj.length; x++) {
myExcelCell.Borders(2).Weight = this.tableBorder ;
oSheet = null;
myWorksheet.Range(myExcelCell, myExcelCell2).Merge();
catch (e) {
jXls.UserControl = true;
}
myExcelCell.Borders(4).Weight = this.tableBorder ;
for (i = 0; i < obj[x].rows[0].cells.length; i++) {
myCellRowSpan = myHTMLTableCell.rowSpan;
* tb.getExcelFile();
TableToExcel.prototype.getExcelFile = function () {
jXls = new ActiveXObject('Excel.Application');
* tb.setColumnWidth(10); //推荐取值10
/*
myExcelCell.Font.ColorIndex = this.fontColor;
this.lineWrap = true; //是否自动换行
var totalRow = 0, totalCol = 0;

this.backGround = 0; //背景颜色：白色 可取调色板中的颜色编号 1/2/3/4....
elDiv.innerHTML=elDivStr;

注意事项：使用JS导出excel需要设置IE的active。注意最佳的是IE8浏览器。至于在java后台实现excel还没去研究，希望各位大神指教。
