可以根据是否隐藏来实现导出功能，如果隐藏则不导出。
主要代码：
[code=JScript]//指定页面区域“单元格”内容导入Excel
function CellAreaExcel()
{
var oXL = new ActiveXObject( "Excel.Application ");
var oWB = oXL.Workbooks.Add();
var oSheet = oWB.ActiveSheet;
var Lenr = PrintA.rows.length;
for (i=0;i <Lenr;i++)
{
var Lenc = PrintA.rows(i).cells.length;
for (j=0;j <Lenc;j++)
{
//在这判断，你的程序运行之后，可以查看源文件看是不是通过隐藏实现的，根据实际情况。
if (PrintA.rows(i).cells(j).style.display== ' ')
{
oSheet.Cells(i+1,j+1).value = PrintA.rows(i).cells(j).innerText;
}
}
}
oXL.Visible = true;
}[/code]
