need help on the spread sheet and the right option to choose

On the VLOOKUP worksheet, you are allowed to select the lookup tables, but not see the values in the cells. How did I do this? A) Using the Cell Format settings, I set the cells to Read Only. B) I erased the cells before saving the worksheet, so there in nothing in the tables. C) Using the Cell Format settings, I set the tables cells to Hidden to make them NOT show up in the formula bar, and then made them grey text on a grey background. OD) I used the Protect Workbook command to set the cells to be invisible.
