A simple way to adding columns and rows in Datatable

// Create a new Datatable

            DataTable dtEmployee = new DataTable("Employee");

           

            // Define Column

            DataColumn DColEmpID = new DataColumn("Emp_ID", System.Type.GetType("System.Int32"));

            DColEmpID.AllowDBNull = false;

            DColEmpID.Caption = "ID";

            DColEmpID.AllowDBNull = false;

            //Adding Columns

            dtEmployee.Columns.Add(DColEmpID);

            DataColumn DColName = new DataColumn("Emp_Name", System.Type.GetType("System.String"));

            DColName.AllowDBNull = false;

            DColName.Caption = "Name";

            dtEmployee.Columns.Add(DColName);

          

            DataColumn DColDept = new DataColumn("Department_ID", System.Type.GetType("System.Int32"));

            DColDept.AllowDBNull = false;

            DColDept.Caption = "Department_ID";

            DColDept.DefaultValue = "1";

            dtEmployee.Columns.Add(DColDept);

           

            DataColumn DColSalary = new DataColumn("Salary", System.Type.GetType("System.Decimal"));

            DColSalary.Caption = "Salary";

            DColSalary.DefaultValue = "0.0";

            dtEmployee.Columns.Add(DColSalary);

            //Add data into columns

            dtEmployee.Rows.Add("1", "Jacky", "21", "5000");

            dtEmployee.Rows.Add("2", "Franky", "21", "7000");
