Front-end js implements dynamically adding selected data to the table

As shown in the figure below, there is attribute content above the table. After selecting it from the drop-down list, the selected content is added to the table below.




Implementation method, (must agree with the backend, because these dynamically added fields are returned by the backend, and the backend will handle it itself. What our frontend needs to do is to map the drop-down data to the table based on the data returned by the backend. And implement addition, deletion, modification and query.)
Generally, the template string method may be used, but sometimes map assignment can be done directly.

as follows.
