System for building structured spreadsheets using nested named rectangular blocks of cells to form a hierarchy where cells can be uniquely referenced using non unique names

摘要

This system is a way of building structured spreadsheets using named nested rectangular block of cells to form a hierarchy. This system allows cells to be referenced by non unique names by using the relative location in the hierarchy of the referenced cell with respect to the cell containing the reference. Clones of a section of the hierarchy can be constructed. The clones are permanently linked to the section of the hierarchy from which they were cloned. Future changes to that section of the hierarchy can be propagated to the clones.
