 /// <summary>
        /// 点击按钮，将内存表导出excel表格！
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Button1_Click(object sender, EventArgs e)
        {

            Aspose.Cells.License li = new Aspose.Cells.License();
            string path = Server.MapPath("License.lic");
            li.SetLicense(path);
            Aspose.Cells.Workbook book = new Aspose.Cells.Workbook();
            Aspose.Cells.Worksheet sheet = book.Worksheets["Sheet1"];
            sheet.FreezePanes(1, 1, 1, 0);
            Aspose.Cells.Style style = book.Styles[book.Styles.Add()];

            style.IsTextWrapped = true;
            style.Font.Size = 10;
