Table properties row count differs from sys.dm_db_partition_stats

 I run this query to see the rowcounts of all my tables

SELECT OBJECT_NAME(OBJECT_ID) TableName, st.row_count
FROM sys.dm_db_partition_stats st
WHERE index_id < 2
ORDER BY st.row_count DESC

For a particular table, its rowcount is listed as 131,000, but if I right-click on the table and view properties, SSMS says it has over 500K.  Maybe the statistics are off and need to be rebuilt?
