Systems, methods, and computer-readable media for implementing conditional rules in a hierarchical table structure are disclosed. The systems and methods may involve maintaining for presentation on a viewable interface a higher-level table structure having first rows, first columns and first cells at the intersections of the first rows and the first columns; maintaining for presentation on the viewable interface a lower-level table structure having second rows, second columns and second cells at the intersections of the second rows and second columns; linking the lower-level table to a specific first cell in the higher-level table; storing a specific conditional rule associating the specific first cell with a plurality of second cells of the lower-level table; receiving qualifying information from each of the plurality of second cells; and triggering the specific conditional rule to thereby update milestone information in the specific first cell of the higher-level table.
