For each group an individual ranking is computed based on the selected ranking attribute(s) and ranking mode. The user must provide at least one attribute on which a ranking should be calculated.

The groups are determined by the unique value combinations of the grouping attribute(s). If no grouping attribute is provided, one ranking will be calculated for the whole table.

Missing values are considered to represent the largest value possible.

The columns in the input table will be called "attributes" to avoid confusion with the table structures in the dialog.
