Filtering data without to DataGridView

I have 3 columns, the first is for the seller, the second is for completing the deal, and the third is for not completing it. I want to know how many deals were made or were not done for each employee through the coordination shown in the picture.

This code give me the total only.

DataTable numOfCalls2Table = new DataTable();
            numOfCalls2Table.Columns.Add("SalesPerson", typeof(string));
            numOfCalls2Table.Columns.Add("Scour", typeof(int));
            numOfCalls2Table.Columns.Add("Dealclosed", typeof(int)); 
            numOfCalls2Table.Columns.Add("Dealnotclosed", typeof(int)); 
            DataView view = new DataView(table); 
            DataTable distinctValues = view.ToTable(true, "SalesPerson", "Dealclosed", "Dealnotclosed");
            if (distinctValues.Rows.Count > 0)
            {
                for (int i = 0; i < distinctValues.Rows.Count; i++)
                {
                    string agentName = distinctValues.Rows[i]["SalesPerson"].ToString();
                    string dealclosed = distinctValues.Rows[i]["Dealclosed"].ToString();
                    string dealnotclosed = distinctValues.Rows[i]["Dealnotclosed"].ToString();
                    DataRow[] agentRows = table.Select($"SalesPerson='{ agentName}'");
                    DataRow[] dealtyperow = table.Select($"Dealclosed='{ dealclosed}'");
                    DataRow[] dealtyperow2 = table.Select($"Dealnotclosed='{ dealnotclosed}'");
                    DataRow newRow = numOfCalls2Table.NewRow();
                    newRow["SalesPerson"] = agentName;
                    newRow["Scour"] = agentRows.Length;
                    newRow["Dealclosed"] = dealtyperow.Length;
                    newRow["Dealnotclosed"] = dealtyperow2.Length;
                    numOfCalls2Table.Rows.Add(newRow);
                }
            }
            return numOfCalls2Table;
