ASP.NET的HTMLTable原样导出到Excel

function PrintTableToExcelEx(objTab)
{
try
{
var xls = new ActiveXObject( “Excel.Application” );
}
catch(e)
{
alert( “您必须安装Excel电子表格软件，同时浏览器须使用“ActiveX 控件”，您的浏览器须允许执行控件。 请点击【帮助】了解浏览器设置方法！”);
return false;
}
xls.visible = true;

var xlBook = xls.Workbooks.Add;
var xlsheet = xlBook.Worksheets(1);

var CurX = 1;
var CurY = 1;

for (var i = 0; i < objTab.rows.length; i++)
{
for (var j = 0; j < objTab.rows[i].cells.length; j++)
{
var cell = objTab.rows[i].cells[j];

var v = cell.outerText;

if ( cell.children != null && cell.children.length != 0 )
{
v = “”;
for ( var k = 0; k < cell.children.length; k++ )
{
var cc = cell.children[k];

switch (cc.type)
{
case “select-one”:
for ( var l = 0; l < cc.options.length; l++ )
if ( cc.options[l].selected ) v += cc.options[l].text;
break;
case “text”:
v += cc.value;
break;
case “checkbox”:
v += cc.checked ? “是” : “否”;
break;
case undefined:
v += cell.outerText;
break;
case “hidden”:
break;
default:
//v += cc.id + “/”;
//v += cc.tagname + “/”;
//v += cc.type + “/”
v += cc.value;
break;
}
}
}

while ( xlsheet.Cells(CurX,CurY).MergeCells ) CurY++;

xlsheet.Cells(CurX, CurY).HorizontalAlignment = 2;
var align = cell.getAttribute(“align”);
switch ( align )
{
case “left”:
xlsheet.Cells(CurX, CurY).HorizontalAlignment = 2;//XlHalign.xlHalignLeft;
break;
case “center”:
xlsheet.Cells(CurX, CurY).HorizontalAlignment = 3;;//XlHalign.xlHalignCenter;
break;
case “right”:
xlsheet.Cells(CurX, CurY).HorizontalAlignment = 4;//XlHalign.xlHalignRight;
break;
}
xlsheet.Cells(CurX, CurY).WrapText = true;
xlsheet.Cells(CurX, CurY).VerticalAlignment = 2;
xlsheet.Cells(CurX, CurY).Value = v;
xlsheet.Cells(CurX, CurY).Borders.LineStyle = 1;

var rowSpan = cell.getAttribute(“RowSpan”);
var colSpan = cell.getAttribute(“ColSpan”);
if ( rowSpan >= 2 || colSpan >= 2 )
{
var R = xls.Range(xls.Cells(CurX, CurY), xls.Cells(CurX + rowSpan – 1, CurY + colSpan – 1));
R.MergeCells = true;
R.Borders.LineStyle = 1;
}
CurY++;
}

CurX++;
CurY = 1;
}
xlsheet.Columns.AutoFit; //自动适应大小
return;
}

调用：

<INPUT style=”WIDTH: 107px” onclick=”javascript：PrintTableToExcelEx(Table1)” type=”button”
value=”导 出” class=”input”>
