Here is quick way to get table size / rows in sql server tables:

SELECT t.NAME AS TableName, p.rows AS RowCounts
, SUM(a.total_pages) * 8 AS TotalSpaceKB
, SUM(a.used_pages) * 8 AS UsedSpaceKB
, (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM sys.tables t
INNER JOIN sys.indexes i
ON t.OBJECT_ID = i.object_id
INNER JOIN sys.partitions p
ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN sys.allocation_units a
ON p.partition_id = a.container_id
WHERE t.NAME NOT LIKE 'dt%'
AND t.is_ms_shipped = 0 AND i.OBJECT_ID > 255
GROUP BY t.Name, p.Rows
ORDER BY t.Name
