篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用asp.net dateaable 做统计表并且网页上显示的表和导出的Excel 一模一样根据领导看报表需求两个报表和一起（add algorithm）相关的知识，希望对你有一定的参考价值。

1.首先使用。net 控件

做两个个表初始属性（

tabBillAdd.Visible = false;
tabBill.Visible = false;

）

2------------------------------------------------------------------------------------------------------------------

接着使用 xml 做魔板

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

<?xml version="1.0" encoding="utf-8" ?>
<table procname="Biz_Item_GetJyzJSZCount" title="{0}{1}加油站建设汇总表" procnameTZ="Biz_Item_GetJyzJSTZCount">
<tr type="rowtitle">
<td width="5%" rowspan="4" height="10%">单位</td>
<td colspan="10" width="100%" TZ="单站投资（万元/座）">加油站座数（座）</td>

</tr>
<tr type="rowtitle">
<td width="4%" rowspan="3">合计</td>
<td colspan="9">新开工项目</td>

</tr>
<tr type="rowtitle">
<td width="5%" rowspan="2">小计</td>
<td rowspan ="2" width="5%">新增</td>

<td colspan="5" width="5%" left="1">其中：</td>
<td width="5%" rowspan ="2" >扩建</td>
<td width="5%" rowspan ="2">迁建</td>

</tr>
<tr type="rowtitle">

<td width="5%">新建 </td>
<td width="5%">收购 </td>
<td width="5%">控股 </td>
<td width="5%">参股 </td>
<td width="5%">租赁 </td>

</tr>
<tr type="rowdata">
<td keyname="regionname"></td>
<td keyname="Total"></td>
<td keyname="SubTatal" ></td>
<td keyname="NewAdd" ></td>
<td keyname="NewBuild"></td>
<td keyname="Purchase"></td>
<td keyname="Holding"></td>
<td keyname="Participation"></td>
<td keyname="Rent"></td>
<td keyname="Extend"></td>
<td keyname="Relocation"></td>

</tr>
</table>

魔板中文部分是标的title 引文部分是根据存储过程一一对应的列明。循环数据用。

比较关键的一歩，合并两个datatable

int leftTable = tabBill.Rows.Count;

#region 填充左表
//如果左表小

if (rightTable > leftTable)
{
int row = rightTable - leftTable;
//创建空行，空列9
TableRow TR;
TableCell TC;
//合计区域纵横
for (int i = 0; i < row; i++)
{

TR.Cells.Add(TC);

}
tabBill.Rows.Add(TR);

}
}
#endregion

foreach (TableRow item in tabBill.Rows)
{
jCount = iCount;
tabBillAdd_Row = tabBill_Row;

if (tabBill_Row == tabBillAdd_Row)
{
for (int i = jCount; i < rightTable; i++)
{
if (jCount == tabBill_Row)
{
jCount++;

int c = tabBillAdd.Rows[i].Cells.Count;

TableCell[] lis = new TableCell[c];
for (int j = 0; j < c; j++)
{
lis[j] = tabBillAdd.Rows[i].Cells[j];

}
item.Cells.AddRange(lis);

}
else
{
break;
}

}
tabBill_Row++;
tabBillAdd_Row++;
tabBillAdd_Row++;

}
else
{
break;

}
iCount++;
}

}

输出 Excel

protected void btnToExcel_Click(object sender, EventArgs e)
{
CreateTable();
Page.Response.Clear();
Page.Response.Buffer = true;
//Page.Response.Charset="GB2312";　　　　
Page.Response.ContentEncoding = System.Text.Encoding.UTF8;
//下面这行很重要， attachment 参数表示作为附件下载，您可以改成 online在线打开　　
//filename=FileFlow.xls 指定输出文件的名称，注意其扩展名和指定文件类型相符，可以为：.doc 　　 .xls 　　 .txt 　　.htm　　　
Page.Response.AppendHeader("Content-Disposition", "online;filename=" + HttpUtility.UrlEncode(lblTitle.Text + ".xls", System.Text.Encoding.UTF8));
//System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true); 　　
//Response.ContentType指定文件类型可以为application/ms-excel 　　 application/ms-word 　　 application/ms-txt 　　 application/ms-html 　　或其他浏览器可直接支持文档　　　
Page.Response.ContentType = "application/ms-excel";
Page.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

tabBill.RenderControl(oHtmlTextWriter);
Page.Response.Write(oStringWriter.ToString());
Page.Response.End();

//CreateTable();
//OutputExcel(tabBill, lblTitle.Text);
