FpSpread添加表头（列名）标注

            for (int j = 0; j < fp.ActiveSheetView.ColumnCount; j++)
            {
                    fp.ActiveSheetView.ColumnHeader.Cells[0, j].Background.BackgroundImageUrl = "../../image/warning.png";
                    fp.ActiveSheetView.ColumnHeader.Cells[0, j].Background.BackgroundRepeat = "no-repeat";
                    fp.ActiveSheetView.ColumnHeader.Cells[0, j].Background.BackgroundPosition = "Left";
                    fp.ActiveSheetView.ColumnHeader.Cells[0, j].Note = "第" + j.ToString() + "列";
            }

在初始化Fpspread的时候设置表头的Node属性

 protected override void Render(HtmlTextWriter writer)
{
     Table cht = this.FpSpread1.FindControl("cht") as Table;
     for (int j = 0; j < FpSpread1.ActiveSheetView.ColumnHeader.Columns.Count; j++)
     {
          if (FpSpread1.ActiveSheetView.ColumnHeader.Cells[0, j].Background.BackgroundImageUrl == "../../image/warning.png")
         {
               cht.Rows[0].Cells[j].Attributes.Add("title", FpSpread1.ActiveSheetView.ColumnHeader.Cells[0, j].Note);
         }
     }
base.Render(writer);
}

在Render中把Note值给title
