The best for trying how function works is to try it in excel, but still…
You want to know what the whole function works or just how partial functions work?
In general, the function addresses to formatted table and to named parts of the table, so it should return value from formatted table, that is x rows from employee name in row and x columns from employee name in this row.
How many depends on what is under “I_E”, “L_E” and “L_H” and “N_S”, I cannot tell without this knowledge.
