In this patent, a child template associated with a parent group of one or more cells of a first data sheet is stored. When a parent cell is added to the parent group, a specific child data sheet is automatically instantiated according to the template. If a value in a first cell of the child data sheet changes, the corresponding value of a cell in the first data sheet is modified.
