Implement table header sorting function with grouped data

php中世界最好的语言Original: 2018-04-26 09:21:172321browse

This time I will bring you the grouped dataTable header sorting function and the noteswhat are the practical cases for realizing the Table header sorting function with grouped data? , let’s take a look.

As shown below:

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

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