Table Lock Escalation - Performance Questions

I have few questions on table lock escalations, please confirm or disprove: 1. Index Scan operator in a query results in Table Lock Escalation ? always or not (small tables) ? 2. When Shared lock is escalated to a table level, it blocks small updates and deletes ? inserts as well ? 3. Is it possible to get counts of table lock_escalation event, grouped by login and then by table ? For example: >login1 - table1 - 11 login1 - table2 - 5 login2 - table1 - 29 etc... Extended Events seemed to allow only one level of grouping if I am not mistaken
