Module:Stat Factors Table

This module is meant to be used by Template:Stat Factors Table Row, which in turn is meant to be used alogside Template:Stat Factors Table.

This module returns the rows used in said table. It accept 8 inputs: skillBase, skillBonus, statMin, statMax, capImportance, capLimit, resultCols, LV, Ln

Any value not given is assumed 0. There are exceptions for the default values of Stat Maximum (99999999) and statMin (0), both of which are defined on Template:Stat Factors Table.

This can probably be further improved. Regardless, this represents a 71% improvement over the ParserFunctions method.
