问题 I have a table with three columns, region, emp_name, salaries. I want to add one more column to this table in excel. That new column should have either 1 or 0. 1 indicates one of the top3 employee based on salaries in a particular region. For example, Region1 has 7 employees, namely emp1, emp2, so on emp7. emp2, emp4, emp7 have top 3 salaries. So in the new column, emp2, emp4, emp7 must have 1 and others have 0. Let's say this table contains n number of regions. 回答1: Put this in D2 and copy
