c#后台动态创建了htmltable，取其innerHtml时，会报错，因为，htmltable控件不支持该属性，要获取其innerHtml使用如下方法
HtmlTable tb=
new HtmlTable();
StringBuilder sb =
new StringBuilder();
StringWriter sw =
new System.IO.StringWriter(sb);
System.Web.UI.HtmlTextWriter htw =
new HtmlTextWriter(sw);
tb.RenderControl(htw);
sb.tostring();
sb.tostring();即所需的innerHtml
