Description
TRVRowGenerationNestedRule is a class of items in the collection TRVRowGenerationCustomRule.SubRules.
The report table has RowGenerationRules property, a collection of TRVRowGenerationRule items. Each item has SubRules property, a collection of TRVRowGenerationNestedRule. Each item in this collection has its own SubRules, and so on. Thus, rules are organized in a tree-like hierarchy.
Like for the root rules, the position of this rule's rows are defined in FirstRow and RowCount properties. However, rows are counted from the parent rule's first row, not from the table beginning.
This class introduces new properties allowing to define outermost columns: SkipLeftColCount and SkipRightColCount. Cells of these columns are not replicated when applying this rule. Instead, they are merged vertically.
