RDLC 报告中第一条记录的位置为空

Question

我做了一个这样的两栏报告：

Name1----------------------------Name3
Address1-------------------------Address3

Name2----------------------------Name4
Address2-------------------------Address4

但突然它开始给出这样的报告：

      ----------------------------Name3
       -------------------------Address3

Name1----------------------------Name4
Address1-------------------------Address4

Name2
Address2

这是我的代码：

 public ActionResult Report()
        {
            LocalReport lr = new LocalReport();
            string path = Path.Combine(Server.MapPath("~/Report"), "Person.rdlc");
            if (System.IO.File.Exists(path))
            {
                lr.ReportPath = path;
            }
            else
            {
                return View("Index");
            }
            List<Person> cm = new List<Person>();

            var viewModel = new PersonIndexData();

            viewModel.People = db.Person
            .Include(k => k.Groups)
            .OrderBy(k => k.Name);

            cm = viewModel.People.ToList();



            ReportDataSource rd = new ReportDataSource("DataSet1", cm);
            lr.DataSources.Add(rd);
            string reportType = "pdf";
            string mimeType = string.Empty;
            string encoding = string.Empty;
            string fileNameExtension = string.Empty;



            string deviceInfo =

            "<DeviceInfo>" +
            "  <OutputFormat>pdf</OutputFormat>" +
            "  <PageWidth>8.5in</PageWidth>" +
            "  <PageHeight>12in</PageHeight>" +
            "  <MarginTop>0.5in</MarginTop>" +
            "  <MarginLeft>0.5in</MarginLeft>" +
            "  <MarginRight>1in</MarginRight>" +
            "  <MarginBottom>0.2in</MarginBottom>" +
            "</DeviceInfo>";

            Warning[] warnings;
            string[] streams;
            byte[] renderedBytes;

            renderedBytes = lr.Render(
                "pdf",
                deviceInfo,
                out mimeType,
                out encoding,
                out fileNameExtension,
                out streams,
                out warnings);


            return File(renderedBytes, mimeType);
        }

即第一条记录的地方是空的。你认为它为什么会发生，我该如何摆脱它？我更改了列间距和边距，但没有用。谢谢。

您无法从表中获取第一列的值。这就是它无法显示第一列值的原因。
