Abstract: Formats are extended automatically to cells in an electronic spreadsheet. Previously blank, newly edited cell(s) are determined to be an extension or within a list of cells based on having a consistent data type, and the like. Next, formatting of the list of cells is examined for consistency. If consistent formatting exists, it is applied to the previously blank, newly edited cell(s). List of cells may include rows, columns, and the like.

Abstract: An electronic spreadsheet is provided for automatically creating, expanding, and validating lists of cells. A list is created by receiving a user request for selecting a cell range, identifying a list range for the selected cell range, determining a header row for the list range, and generating a border for surrounding the list range. A list is expanded by determining that one or more cells are adjacent to the list and automatically expanding the list to include the new cells. A list is validated by determining a data type of data entered into the list and comparing the data type of the data entered into the list to a list data type. If, as a result of the comparison, the data type of the data entered into the list does not match the list data type, then the data type of the data entered into the list is invalid.

Abstract: Methods for automatically, without user instruction, extending a format and/or a formula to include a cell in an electronic spreadsheet. A previously blank newly edited cell may be determined to be an extension to or within a list of cells. A list of cells may be defined as a number of previous cells having a consistent data type. 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.
