Try this
Console.WriteLine("{0,10}{1,10}{2,10}{3,10}{4,10}",
customer[DisplayPos],
sales_figures[DisplayPos],
fee_payable[DisplayPos],
seventy_percent_value,
thirty_percent_value);
where the first number inside the curly brackets is the index and the second is the alignment. The sign of the second number indicates if the string should be left or right aligned. Use negative numbers for left alignment.
