Hi,

I have made this case from the example website :
https://live.datatables.net/vaqerila/12/edit

How can I count the groups created by the RowGroup extension and use this counter in the footer (see the infos in red in the footer) ?

Thank you

There isn't a way to count the number of groups. However you can use column().data() with unique() and count() to get the info. For example:

I have use it for the general average in the footer of a DT.
This table is (almost) finished

Thanks Kevin
