Final answer:
To modify the Dec 18 worksheet so gridlines will print, follow these steps. Click on the "View" tab in the Excel ribbon, then check the "Gridlines" option in the "Show" group. This will ensure that gridlines are included when you print the worksheet.
Explanation:
In Excel, gridlines are the faint lines that separate cells and help in better visualization of data. However, by default, gridlines are not set to print. To modify the Dec 18 worksheet and make sure gridlines are included in the printout, you need to access the "View" tab. This tab is located in the Excel ribbon, typically at the top of the Excel window.
Once you're in the "View" tab, look for the "Show" group. Here, you'll find an option labeled "Gridlines." By checking this option, you instruct Excel to include gridlines in the printout. It's a simple yet crucial step to ensure that the printed version of your worksheet maintains the visual structure provided by gridlines, aiding readability and comprehension.
After making this adjustment, proceed with printing the worksheet as you normally would. The gridlines will now be part of the printed document, enhancing the clarity of your data. This straightforward modification is valuable for anyone who wants to present or share Excel data in a way that retains the original structure and layout.
