How to separate records with different values in datagridview and add empty row between them?

DataTable dt = new DataTable();
           dt.Columns.Add(new DataColumn("Id"));
           dt.Columns.Add(new DataColumn("Name"));
           for (int i = 0; i < 5; i++)
           {
               DataRow dr = dt.NewRow();
               if (i % 2 == 0)
               {
                   dr["Id"] = "1";
                   dr["Name"] = "Country" + i.ToString();
               }
               else
               {
                   dr["Id"] = "";
                   dr["Name"] = "";
               }
               dt.Rows.Add(dr);
           }
           this.grd.DataSource = dt;
           this.grd.DataBind();
