Quick SQL - getting the size of all tables in a database

I use this little chunk of SQL code almost every day. It gives you a relatively accurate report of the size of each table in the database, including indexes. Very handy!

select
   TableName   = convert(varchar(100) ,sysobjects.name)    
   ,TotalRows  = max(sysindexes.rows)    
   ,MbData     = floor(sum(convert(real ,sysindexes.dpages)) * spt_values.low / 1048576)   
   ,MbTotal    = floor(sum(convert(real ,sysindexes.used)) * spt_values.low / 1048576  )
from sysobjects 
join sysindexes   
   on sysobjects.id = sysindexes.id
join master.dbo.spt_values spt_values 
   on spt_values.number = 1 
   and spt_values.type = 'E' 
where
   sysobjects.type = 'U'   
   and indid in (0,1,255)
group by    
   sysobjects.name   
   ,spt_values.low
order by 4 desc
