Question I am working in Excel 365. There is a template for calculating DDB depreciation. I am trying to learn more about the "@" in "[@[Acquisition Cost]]<>0". I am not sure what to look under, array, database, tables, etc. Where can I learn more about it?
Answer Whenever you see brackets in the reference then it denotes that it refers to Table References.
In your example [Acquisition Cost] refers to one of the column header of that table. That column header name is Acquisition Cost.
@ refers to current row of that referred table column.
Go through the below links to know more about table.
