Table and its solution code.

Question

(a) 6" slab
SPAN (ft)	20FT ROADWAY				40FT ROADWAY
	ONE WAY		TWO WAY		ONE WAY		TWO WAY
	W	T	W	T	W	T	W	T
5	150	150	40	30	150	150	150	120
5.5	96	150	40	30	96	150	65	120

16	7	6	4	4	7	6	4	4

this is an excel table. just .1 % of the work. 
i need to select table on the basis of slab, then has to select row. .then will Slect 40ft roadway widht or 20ft width roadway width by some conditions as shown in the code below. 
i dont want to do all these conditions manually, and as far CSV is concerned i am not getting the concept of CSV in general form. i dont know how to implement it in my situation. Plz help, there are 26 tables morever its just 5 percent of the program. so i am stuck. can someone give me better solution.i want to save my time. i donot want to do it manually.
i have defined all variabbles. 

 if (Thickness == 6)// select slab table

            {

                Console.WriteLine("Looking into 6 inch Slab thickness Table . . .");

                Console.ReadLine();

                if (Span == 5.00) // select span row in the span column

                {

                    Console.WriteLine("Now selecting the Roadway column. . .");

                    Console.ReadLine();

                    if (Width <= 24) // select 20' roadway

                    {

                        Console.WriteLine("For ONE WAY: ");

                        Console.WriteLine("(a) Wheel = 150");

                        Console.WriteLine("(b) Track = +150");

                        Console.WriteLine("For TWO WAY: "); 

                        Console.WriteLine("(a) Wheel = +40");  

                        Console.WriteLine("(b) Track = +30");

                        Console.ReadLine();

                    }

                    if ((Width > 24) && (Width < 30)) //select 40 ft road with 18 percent reduction factor

                    {

                        Console.WriteLine("For ONE WAY: ");

                        Console.WriteLine("(a) Wheel = +123");

                        Console.WriteLine("(b) Track = +123");

                        Console.WriteLine("For TWO WAY: ");

                        Console.WriteLine("(a) Wheel = 123");

                        Console.WriteLine("(b) Track = +98.4");

                        Console.ReadLine();

                    }

                    if (Width >= 30)// Select 40 ft roadway

                    {

                        Console.WriteLine("For ONE WAY: ");

                        Console.WriteLine("(a) Wheel = 150");

                        Console.ReadLine();
