Add Sum of cells from Data Table column to a new column on the same row.

I have a Data Table with two or three weight and cube columns on each row. What I need to do is get a total for each into a weight total and cube total column. Can anyone tell me how to get this done ?

DGV.DataSource = dataTable;

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can accomplish this with DataColumn expressions:
using System.Data;
using System.Windows.Forms;

namespace EE_Q28690908
	public partial class Form1 : Form
		private DataTable table = new DataTable();

		public Form1()
			table = GetTable();
			dataGridView1.DataSource = table;

		private DataTable GetTable()
			DataTable table = new DataTable();
			table.Columns.Add("Type", typeof(string));
			table.Columns.Add("Weight1", typeof(int));
			table.Columns.Add("Weight2", typeof(int));
			table.Columns.Add("Cube1", typeof(int));
			table.Columns.Add("Cube2", typeof(int));
			table.Columns.Add("WeightTotal", typeof(int), "Weight1 + Weight2");
			table.Columns.Add("CubeTotal", typeof(int), "Cube1 + Cube2");

			table.Rows.Add("Order", 250, 15, 25, 3);
			table.Rows.Add("Order", 1000, 300, 100, 15);
			return table;

You could also use events to calculate the columns.
