從數據集和數據表中生成水晶報表

Question

我需要在只有獨立數據集（未連接到任何類型的數據庫）的應用程序中的Crystal Reports中生成報表。另外，我需要根據DataTable中的值生成報告。

您能否請我看看，我是一個新手。我有一個模板，但我不知道如何從DataTable生成報告，也不知道如何插入到模板中。

        root.Text = "Sample Report By Using Data Table!!"; 
  
        // Binding the crystalReportViewer with our report object. 
        crystalReportViewer1.ReportSource = objRpt; 
       }
