以下内容为网络搜集，方便自己使用。出处不详（我忘了从哪找的了，呵呵）。

-------------------------------------------------------------------------------------------------------------------------------------

使用JavaScript中的ActiveXObject填充并设置Excel格式

1.创建实例并创建工作表

var XLObj = new ActiveXObject("Excel.Application");//创建Excel实例

var xlBook = XLObj.Workbooks.Add;                         //新增工作簿

var ExcelSheet = xlBook.Worksheets(1);                   //创建工作表

2.保存表格

ExcelSheet.SaveAs("C:\\TEST.XLS");

3.使 Excel 通过 Application 对象可见

ExcelSheet.Application.Visible = true;或者ExcelSheet.Visible=true;

4.打印

xlBook.PrintOut;或者:ExcelSheet.PrintOut;

5.关闭

xlBook.Close(savechanges=false);或者ExcelSheet.Close(savechanges=false);

6.结束进程

ExcelSheet.Application.Quit()或者XLObj.Quit(); XLObj=null;

7.页面设置

ExcelSheet.ActiveSheet.PageSetup.LeftMargin= 2/0.035;         //页边距 左2厘米

ExcelSheet.ActiveSheet.PageSetup.RightMargin = 3/0.035;      //页边距 右3厘米，

ExcelSheet.ActiveSheet.PageSetup.TopMargin = 4/0.035;        //页边距 上4厘米，

ExcelSheet.ActiveSheet.PageSetup.BottomMargin = 5/0.035;   //页边距 下5厘米

ExcelSheet.ActiveSheet.PageSetup.HeaderMargin = 1/0.035;   //页边距 页眉1厘米

ExcelSheet.ActiveSheet.PageSetup.FooterMargin = 2/0.035;    //页边距 页脚2厘米

ExcelSheet.ActiveSheet.PageSetup.CenterHeader = "页眉中部内容";

ExcelSheet.ActiveSheet.PageSetup.LeftHeader = "页眉左部内容";

ExcelSheet.ActiveSheet.PageSetup.RightHeader = "页眉右部内容";

ExcelSheet.ActiveSheet.PageSetup.CenterFooter = "页脚中部内容";

ExcelSheet.ActiveSheet.PageSetup.LeftFooter = "页脚左部内容";

ExcelSheet.ActiveSheet.PageSetup.RightFooter = "页脚右部内容";

8.对单元格操作，带*部分对于行，列，区域都有相应属性

ExcelSheet.ActiveSheet.Cells(row,col).Value = "内容";                //设置单元格内容

ExcelSheet.ActiveSheet.Cells(row,col).Borders.Weight = 1;        //设置单元格边框*()

ExcelSheet.ActiveSheet.Cells(row,col).Interior.ColorIndex = 1;    //设置单元格底色*(1-黑色，2-白色，3-红色，4-绿色，5-蓝色，6-黄色，7-粉红色，8-天蓝色，9-酱土色..可以多做尝试)

ExcelSheet.ActiveSheet.Cells(row,col).Interior.Pattern = 1;         //设置单元格背景样式*(1-无，2-细网格，3-粗网格，4-斑点，5-横线，6-竖线..可以多做尝试)

ExcelSheet.ActiveSheet.Cells(row,col).Font.ColorIndex = 1;        //设置字体颜色*(与上相同)

ExcelSheet.ActiveSheet.Cells(row,col).Font.Size = 10;                //设置为10号字*

ExcelSheet.ActiveSheet.Cells(row,col).Font.Name = "黑体";        //设置为黑体*

ExcelSheet.ActiveSheet.Cells(row,col).Font.Italic = true;             //设置为斜体*

ExcelSheet.ActiveSheet.Cells(row,col).Font.Bold = true;             //设置为粗体*

ExcelSheet.ActiveSheet.Cells(row,col).ClearContents;                //清除内容*

ExcelSheet.ActiveSheet.Cells(row,col).WrapText=true;               //设置为自动换行*

ExcelSheet.ActiveSheet.Cells(row,col).HorizontalAlignment = 3; //水平对齐方式枚举* (1-常规，2-靠左，3-居中，4-靠右，5-填充 6-两端对齐，7-跨列居中，8-分散对齐)

ExcelSheet.ActiveSheet.Cells(row,col).VerticalAlignment = 2;      //垂直对齐方式枚举*(1-靠上，2-居中，3-靠下，4-两端对齐，5-分散对齐)

//行，列有相应操作:

    ExcelSheet.ActiveSheet.Rows(row).

    ExcelSheet.ActiveSheet.Columns(col).

    ExcelSheet.ActiveSheet.Rows(startrow+":"+endrow).                   //如Rows("1:5")即1到5行

    ExcelSheet.ActiveSheet.Columns(startcol+":"+endcol).                //如Columns("1:5")即1到5列

    //区域有相应操作:

    XLObj.Range(startcell+":"+endcell).Select;

        //如Range("A2:H8")即A列第2格至H列第8格的整个区域

    XLObj.Selection.

    //合并单元格

    XLObj.Range(startcell+":"+endcell).MergeCells = true;

        //如Range("A2:H8")即将A列第2格至H列第8格的整个区域合并为一个单元格

    或者:XLObj.Range("A2",XLObj.Cells(8, 8)).MergeCells = true;

9.设置行高与列宽

ExcelSheet.ActiveSheet.Columns(startcol+":"+endcol).ColumnWidth = 22;//设置从firstcol到stopcol列的宽度为22

ExcelSheet.ActiveSheet.Rows(startrow+":"+endrow).RowHeight = 22;//设置从firstrow到stoprow行的宽度为22

Var myrange oSheet.Range(oSheet.Cells(2,1),oSheet.Cells(2,6));

myRange.Columns.AutoFit()

myRange.Rows.AutoFit()//好像不太管用

//设置该区域为自适应高度和宽度

使用JavaScript将表格内容导出到Excel的方式

1.整个表格拷贝到EXCEL中

function CopyTable(tableid)

{

     //整个表格拷贝到EXCEL中

     var curTbl = document.getElementById(tableid);

     var oXL = new ActiveXObject("Excel.Application");

     //创建AX对象excel

     var oWB = oXL.Workbooks.Add();

     //获取workbook对象

     var oSheet = oWB.ActiveSheet;

         //激活当前sheet

     var sel = document.body.createTextRange();

     sel.moveToElementText(curTbl);

     //把表格中的内容移到TextRange中

     sel.select();

     //全选TextRange中内容

     sel.execCommand("Copy");

     //复制TextRange中内容

     oSheet.Paste();

     //粘贴到活动的EXCEL中

     oXL.Visible = true;

     //设置excel可见属性

}

2.把单元格内容拷贝到Excel,并设置单元格格式.

function method2(tableid) //读取表格中每个单元到EXCEL中

{

     var curTbl = document.getElementById(tableid);

     var oXL = new ActiveXObject("Excel.Application");

     //创建AX对象excel

     var oWB = oXL.Workbooks.Add();

     //获取workbook对象

     var oSheet = oWB.ActiveSheet;

     //激活当前sheet

     var Lenr = curTbl.rows.length;

     var y=document.getElementById('dropYear');

     var m=document.getElementById('dropMonth');

     //取得表格行数

     oSheet.Cells( 1, 1).value='商户名称：工商银行商城';

     oSheet.Range(oSheet.Cells(1,1),oSheet.Cells(1,6)).Merge()

     oSheet.Cells(2,1).value=日期; '+y.options[y.selectedIndex].value+'-'+m.options[m.selectedIndex].value;

     oSheet.Range(oSheet.Cells(2,1),oSheet.Cells(2,6)).Merge()

     oSheet.Cells( 3, 1).value='销售情况'

     oSheet.Range(oSheet.Cells(3,1),oSheet.Cells(3,6)).Merge()

     oSheet.Cells( 3, 1).HorizontalAlignment=3;

     oSheet.Cells( 3, 1).Font.Size=14;

     oSheet.Cells( 3, 1).Font.Bold = true;

     oSheet.Range(oSheet.Cells(4,1),oSheet.Cells(4,6)).Merge()

     oSheet.Cells(4,1).value=document.getElementById('lbMessage').innerText;

     for (i = 0; i < Lenr; i++)

     {

     var Lenc = curTbl.rows(i).cells.length;

//取得每行的列数

         for (j = 0; j < Lenc; j++)

         {

             oSheet.Cells(i + 5, j + 1).value = curTbl.rows(i).cells(j).innerText;

             //赋值

         }

     }

     oSheet.Cells(i+6,2).value=document.getElementById('hidSum').value;

     oSheet.Columns.AutoFit();

     oSheet.Rows.AutoFit();

     oSheet.Rows(4).RowHeight = 30;

     oXL.Visible = true;

     //设置excel可见属性

     oXL.Quit();

     oXL = null;

     idTmr = window.setInterval("Cleanup();",1);//强制释放资源

}

function Cleanup()//清除Excel资源

{

     window.clearInterval(idTmr);

     CollectGarbage();

}

使用JavaScript按照表格格式复制内容到剪切板

1.在Excel中进行粘贴

function copytable()

{

    var content=''

    var tb=document.getElementById('GVmain');

    var rows=tb.rows;

    for(var i=0;i<rows.length;i++)

    {

          var cells=rows[i].cells;

          for(var j=0;j<cells.length;j++)

          {

              content +=cells[j].innerText.toString()+'\t';

          }

         content +='\n';

     }

     if(content!='')

     {

         clipboardData.setData("text",content);

         alert("复制成功!")

     }

}
