Dynamic tables provide you with a host of additional features that a simple manual data list will not. For instance, look at the first section (A1:F6). This is how most manual lists are maintained within a simple Microsoft Excel worksheet. By simply selecting the range, in this example: (A9:F14), selecting the Insert Tab in the toolbar ribbon, then selecting Table you will see what starts as what is displayed in the first section become what is now displayed in the second section.
Now, you will see some additional feature available to you. First, you now have a dynamic table that will automatically expand as you add data to the bottom of the table and formatting and formulas will autofill down. Second, AutoFilter is now assigned to your table so that you may filter and sort as desired. Table formatting has been introduced in the form of banding to assist in easier readability. Lastly, the table is now considered a named range that can easily be used in a multitude of lookup and other statistical formulas. A win-win all around. Play with the possibilities.
