Adds a certain number of empty rows with missing values (or a constant) to the input table. This can be useful when used in a report table to ensure that a table has a minimum number of rows, which are then shown as blank rows. The content of the appended rows can be defined in the dialog, the default is to fill the corresponding cells with missing values. Note that the reporting engine allows you to format cells containing missing values (or any other specific value) using the "Map" feature. For instance, if you want to format missing values (shown as NaN in the report) as blank fields, add a map rule isNaN(row["Column x"]), which needs to evaluate to True.
