Question

I am using Fastreport for mvc core project but i have a problem for created table in fastreport. My created table includes some blank between rows or column but there is no problem exporting the prepared report as pdf,excel etc.. I am designing on fastreport designer and showing previewing, there is no any problem.How can i overcome this problem?

        WebReport webReport = new WebReport();

        var dataSet = new DataSet();
        DataTable table=new DataTable();
        table.Columns.Add("ID", typeof(int));
        table.Columns.Add("AD", typeof(string));
        table.Columns.Add("SOYAD", typeof(string));
        table.Columns.Add("TARIH", typeof(DateTime));

        // Here we add five DataRows.
        table.Rows.Add(25, "Indocin", "David", DateTime.Now);
        table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);
        table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);
        table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);
        for(int i = 0; i < 500; i++)
        {
            table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);
        }

        dataSet.Tables.Add(table);

        // FastReport.Utils.Config.WebMode = true;

        FastReport.Utils.Config.WebMode = true;
        webReport.Report.Load("C:\\......\\isimsiz.frx");
        webReport.Report.RegisterData(table, "DATA");
        webReport.Report.GetDataSource("DATA").Enabled = true;
        var db = (DataBand)webReport.Report.FindObject("Data1");
        db.DataSource = webReport.Report.GetDataSource("DATA");
        webReport.Report.SetParameterValue("ParamAdi","Gökhan");

        webReport.Report.Prepare();





        ViewBag.WebReport = webReport;
