构建GridView多表头及添加尾末汇总行

最近在做项目资金统计，需要对GridView的表头进行重新构建，如多行表头，尾行汇总等。先看下展示效果。

这里我们可以在GridView控件的RowCreated事件中对数据行的格式进行处理。

 protected void sgvCapitalDetailList_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Header)
            {
                RebuildHeader(e.Row.Cells);
            }
            if (e.Row.RowType == DataControlRowType.Footer)
            {
               ReBuildFooter(e.Row.Cells);
            }
        }

        /// <summary>
        /// 重建表尾
        /// </summary>
        /// <param name="tcFooter">表尾单元格集合</param>
        void ReBuildFooter(TableCellCollection tcFooter)
        {
            tcFooter.Clear();
            GridViewRow rowFooter = new GridViewRow(0, 0, DataControlRowType.Footer, DataControlRowState.Normal);
            rowFooter.BorderWidth = 1;
            rowFooter.Attributes.Add("class", "yy_sgv_fixRow1");
            rowFooter.Attributes.Add("style", "z-index:1000;background-color:#eafbc9;;font-family:宋体;font-weight:bold;border:1px #719626 solid;");
