By Default Excel does not print out gridlines with your Excel data. Below is how to make Excel publish out the gridlines for less complicated record readability.

When you prepare to print out the Excel document click Page Layout tab on the Ribbon, after that click Page Setup

In the Page Setup dialog box click the Sheet tab. Place a checkmark beside Gridlines as well as click OK. When you print your record you will currently have the gridlines show up with your data!
