Hello, all:

What is the meaning of columns avg_space and empty_block in table dba_tables? I used command to analyze the tables and select from dba_tables to get table statistics. But something feel strange to me. I have table A and B:

avg_row_len num_rows avg_space empty_block
A 60 650 1541 109
B 82 16680 551 95

It suppose that B consumes more space.

Could you help me explain it? Thanks.
