How to Display Multiple DataTables Data in one CrystalReport

I have 2 DataTables one is Created From Data Entered In TextBoxes and Another DataTable Is Created From Database Sql Server. Now I Have to Show Both The DataTables Data In Single Crystal Report.

I Had Written Below Code,But It Is Showing Empty Crystal Report :

private void btnViewCrystal_Click(object sender, EventArgs e)

{

EmployeeDataSet ds = new EmployeeDataSet();

// Create First DataTable

DataTable t = ds.Tables.Add("EmpDetails");

t.Columns.Add("EmpNo", Type.GetType("System.Int32"));

t.Columns.Add("EmpName", Type.GetType("System.String"));

t.Columns.Add("DateOfBirth", Type.GetType("System.String"));

t.Columns.Add("Address", Type.GetType("System.String"));

t.Columns.Add("Country", Type.GetType("System.String"));

DataRow r;

r = t.NewRow();

r["EmpNo"] = txtEmpNo.Text;

r["EmpName "] = txtName.Text;

r["DateOfBirth"] = txtDay.Text + " /" + txtMonth.Text + " /" + txtYear.Text;

r["Address"] = txtAddress.Text;

r["Country"] = txtCountry.Text;

t.Rows.Add(r);

OleDbConnection cn = new OleDbConnection(ConfigurationManager.ConnectionStrings["Name_Correction.Properties.Settings.NameCorrectionConnectionString"].ConnectionString);

cn.Open();

OleDbCommand cmd = new OleDbCommand();

OleDbDataAdapter da = new OleDbDataAdapter();

DataTable dt = new DataTable();

cmd.Connection = cn;

cmd.CommandText = "select * from tblDepartment Where DeptNo=@DeptNo";

cmd.Parameters.Add("DeptNo", OleDbType.Integer).Value = int.Parse(txtDeptNo.Text);

da.SelectCommand = cmd;

dt.Clear();

da.Fill(dt);

ds.Tables.Add(dt);

//To Show The CrystalReport1 In CrystalReportViewer

CrystalReport1 objRpt = new CrystalReport1();

objRpt.SetDataSource(ds);

crystalReportViewer1.ReportSource = objRpt;

crystalReportViewer1.Refresh();

}
