How To Make A Table - Put Label For Each Column To Identify What Values Are

So I just processed this rectangular array and made myself a table. I want to put a label for each column to identify what the values are. My attempt at this failed miserably, because it looks horrible. Here is the necessary code.

Java Code:

System.out.println();
System.out.println("FORMATTED RESULTS");
System.out.println(results);
values[rowCount][0] = currency.format(monthlyInvestment);
values[rowCount][1] = percent.format(interestRate/100);
values[rowCount][2] = Integer.toString(years);
values[rowCount][3] = currency.format(futureValue);
rowCount++;

[Code] .....

If you are to compile this yourself, you would see the horrible output at the end. I would like to know how to properly align each label with its corresponding column.
