If a list of cells exists and the previously blank newly edited cell also includes the consistent data type, the previously blank newly edited cell is considered to be an extension of or within a list. The cells in the list are then examined for consistent formatting. If consistent formatting exists in the list, the consistent formatting is applied to the previously blank newly edited cell. Also, the cells in the list are examined for consistent formulas. The rows containing the cells in the list are each examined for a consistent formula having all supporting cells populated. If such a consistent formula is detected, it is applied to the row containing the previously blank newly edited cell. Also, the spreadsheet is scanned for aggregating formulas that reference the cells within the list. If an aggregating formula is discovered, it is updated to include…
