Method Detail

### addCell

    void addCell(WritableCell cell)
                 throws WriteException,
                        jxl.write.biff.RowsExceededException

  Adds a cell to this sheet The RowsExceededException may be caught if client code wishes to explicitly trap the case where too many rows have been written to the current sheet. If this behaviour is not desired, it is sufficient simply to handle the WriteException, since this is a base class of RowsExceededException
