Join the two tables; group the joining result (or the sub table) by ID, count records in each group, and find the largest number of records to get the value of colNames, the dynamic columns list; perform distinct over the joining result (or the main table) by ID to get the key word list rowKeys for the target table; implement the dynamic transposition algorithm according to colNames and rowKeys. A transposition is to rotate information from one row or column to another to change the data layout, for the purpose of making observations from a new perspective.
