Method Detail

addCell

public 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

jxl.write..WriteException

jxl.write.biff.RowsExceededException

WriteException
