Got it, its the TABLES table that you want to look at. It works in the same way as I described earlier with the GROUPS table.
The column TB_TABLE_NAME contains each table and all the other columns are the permissions that are possible on that table. These columns contain a string of '0's and '1's. This represents the Groups in the GROUP table as per the GR_GROUP_ID order. I hope that makes sense to you. Let me know if you need an example to clarify it.
