There are two tabular formats generated by -m 8 and 9, respectively. Both list only tab delimited key alignment statistics without giving the actual alignments. The differences between the two tabular formats are that 1) -m 8 only sorts the HSPs from individual database sequences, and 2) there is no header separate HSPs from different database sequences. So if there are no hits found for a given query, -m 8 will skip it, while -m 9 will print out the header before going on to the next query.
The order of fields for BLAST result in tabular format is: query id, database sequence (subject) id, percent identity, alignment length, number of mismatches, number of gap openings, query start, query end, subject start, subject end, Expect value, HSP bit score.
