Before the advent of financial calculators (and Excel), tables were often used in the calculation of present values and future values. Using a two-way data table, create a future value table and a present value table. To make the table a little more interesting, make sure the table will calculate the future values and present values for different dollar amounts. One thing we should note here is that you will not be able to simply copy and paste the tables presented earlier in this workbook. When a data table is created, you cannot insert or delete rows or columns at a later point in time.
