Method and system of sharing common formulas in a spreadsheet program and of adjusting the same to conform with editing operations

摘要

A method and system of adjusting shared formulas in a spreadsheet program in response to editing operations. Upon an editing operation, the boundary line of cells that are shifted is determined with respect to the location of cells sharing a common formula and to the location of the cell references therein. On the bases of the relative location of the boundary line, the present invention adjusts the shared formulas. Furthermore, a method and system is provided for partitioning large cell groups having common formulas into smaller areas of common formulas and sharing a separate shared formula for each smaller area in order to allow efficient adjustments of shared formulas in response to editing operations.
