Provides two types of classification tree formats, tree structures in the form of tables and drop-down boxes
You can customize the styles of tables and drop-down boxes, customize which column of parameters is used as formatted data, customize hierarchical relationship parameters, and customize tables Column name, you can also set the time format.
All this can be done automatically for you. If you think it’s good, don’t forget to give it a like...
