Example analysis of jQuery implementation of Table header sorting with grouped data_jquery

The example in this article describes how jQuery implements Table header sorting with grouped data. Share it with everyone for your reference, the details are as follows:

As shown below:

Requirement: When clicking on the table header to sort, the data hierarchical relationship between "Group" and "Group Details" remains unchanged

I found a regular table sorting from the Internet, modified it to meet the "group support", and posted it here for backup
