Worksheet background
When we make reports, the goal is for them to be both functional and beautiful. Their background can also contribute to the appearance of the worksheet in a positive way. It is a picture that is placed behind the tables, charts, and other elements of the report. If after hiding it, we also hide lines separating cells (Gridlines) reports will look like they were not created in Excel. But, more importantly, users will be able to easily find the necessary information.
