RN is a awesome technology, and Facebook's very thinking team has created a new technology that has changed the native development community. But RN itself is doubtful, RN is to solve what problems exist? What problems did RN solve after the birth of a year? Through analyzing the idea of

Here, the transposed column is empno, and the fixed column is mgr and deptno.
Another way to convert rows to columns is to change the row values in the same group to a single column value, but the transposed row values are not changed to column names:

At this stage, our RN practice is based on the published app, such as replacing a sub-module that enters from a portal into an RN page. Then we can design this submodule as a generic RN container, and all RN pages jump inside the RN container.
