</table>//个人认为要我导出这张表的设计者有点怪咖
后台点击事件代码：
--------部分代码来自百度
Bind();------Repeater1的数据源，特别提醒下，少了导出的就是张空表
Response.Clear();
Response.Charset = "GB2312";
Response.Buffer = true;

System.IO.StringWriter sw = new System.IO.StringWriter(myCItrad);

//ClearControls(Repeater1);------用来清除表中所用的控件（button），此表木有
this.Repeater1.RenderControl(hw);
string str = hw.InnerWriter.ToString();

=====对数据源做出相应的条件处理======
string all = sw.ToString();
Regex r = new Regex("<img.[^>]+[>]+", RegexOptions.ExplicitCapture);//通过正则去除数据源中‘ img ‘标签
string result1 = r.Replace(all, "");
Regex rr = new Regex(@"<a[^>]*>|</a>$");//通过正则去除数据源‘ a ‘标签并保留‘ a ‘标签的文本值
string result = rr.Replace(result1, "");
Response.Write(result);
Response.Write("</table>");
Response.Write("<script type=‘text/javascript‘ language=‘javascript‘>");
Response.Write("$(function{");
Response.Write("$(‘a‘).removeAttr(‘href‘);");
Response.Write("});");
Response.Write("</script>");
Response.Write("</body></html>");
Response.Flush();
Response.End();
