RDLC报告只生成多行空白数据

Question

我在这里遇到一个问题，我的 RDLC 报告只生成多页空白行。我已经在数据源中设置了我的数据集并完成了每个步骤过程。我什至使用 DataSet 中的预览数据及其工作测试了它。需要知道这里还缺少什么。

我已经在我的带有参数的报告数据中包含了一个数据集

我的数据源实例：

这里是文字代码：

private PHARM_OPDSALES _PHARM_OPDSALES = null;
    public pharm_printprev(UserControl callingForm)
    {
        _PHARM_OPDSALES = callingForm as PHARM_OPDSALES;
        InitializeComponent();
    }

    private void pharm_printprev_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'dSdispense_sum.DataTable1' table. You can move, or remove it, as needed.
        
        // TODO: This line of code loads data into the 'dSdispense_sum.DataTable1' table. You can move, or remove it, as needed.
        // TODO: This line of code loads data into the 'dSdispense_sum.DataTable1' table. You can move, or remove it, as needed.
        
        lbl_print_refrsh_Click(sender, e);
    }

    private void lbl_print_refrsh_Click(object sender, EventArgs e)
    {
        string df1 = dm_dtepckr.Value.ToString("yyyy-MM-dd hh:mm:ss tt");
        string dt1 = dm_dtepckr2.Value.ToString("yyyy-MM-dd hh:mm:ss tt");


        //this.DataTable1TableAdapter.Fill(this.DSdemograph.DataTable1, DtePckr1.Value = this._hims_dmgrphc.DTPicker, DtePckr2.Value = this._hims_dmgrphc.DTPicker1, _ctynme.Text = this._hims_dmgrphc.CtyName);

        this.dataTable1TableAdapter.Fill(this.DSdispense_sum.DataTable1,  dm_dtepckr.Value = this._PHARM_OPDSALES.DTPicker, dm_dtepckr2.Value = this._PHARM_OPDSALES.DTPicker1);

        ReportParameter[] Rparam = new ReportParameter[]
        {
          
          new ReportParameter("DMFrom", df1),
          new ReportParameter("DMTo", dt1),
          

        };
        rptdsch1.LocalReport.SetParameters(Rparam);
        rptdsch1.RefreshReport();
    }

在调试运行时结果期间。
