While the default setting in Pivot Tables is to show blank cells when there is no applicable data for a row or column label, it provides the option to Replace Blank Cells with Zeros.
Replacing Blank Cells with Zeros in Pivot Tables is a good practice, as it avoids the possibility of blank values in the Pivot Table being attributed to missing data, calculation error or mistakes in creating the Pivot Table.
