      • build

        public Sheet build()
        Builds sheet from parent workbook and 2D array with cell values. Creates rows anyway (even if row contains only null cells), creates cells if either corresponding array value is not null or createEmptyCells property is true. The conversion is performed in the following way:
        • Numbers become numeric cells.
        • java.util.Date or java.util.Calendar instances become date cells.
        • String with leading '=' char become formulas (leading '=' will be truncated).
        • Other objects become strings via Object.toString() method call.
        Returns:
        newly created sheet
