万能报表小数变科学计数解决方案:目前只能使用脚本变通处理，示例脚本如下

private void tableCell17_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) {

 XRTableCell xrtableCell  = sender as XRTableCell ;

      Decimal dData = 0.0M;

      if(xrtableCell.Text.Contains("E"))

      {

        dData = Decimal.Parse(xrtableCell.Text, System.Globalization.NumberStyles.Float);

        xrtableCell.Text = string.Join("", dData);

      }   

    }
