MySQL table & index sizes

This almost works for getting the table stats - needs a tweak to correctly report database and index space usage, but don't have time to check that now.

table_name, engine, table_rows as tbl_rows, avg_row_length as rlen,
floor((data_length+index_length)/1024/1024) as allMB,
floor((data_length)/1024/1024) as dMB,
floor((index_length)/1024/1024) as iMB
from information_schema.tables
where table_schema=database()
order by (data_length+index_length) desc;
