First organize the basic data source, such as the classification and corresponding subitems are listed separately, and it is recommended to use naming scope management; 2. Use the "Data Verification" "INDIRECT" function to achieve linkage, provided that the main pull-down option is consistent with the named area name; 3. Use the FILTER function (suitable for Excel365 or 2021 and above), and achieve more flexible linkage through dynamic filtering.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
