Group by column transformation

[theangrydev]

It would be great if we could group by a transformation of a column. For example if I have a column with values "[ABC] 123", "[ABC] 456", "[GEH] 678" I want to be able to group by "[ABC]" and "[GEH]".

A current workaround is to add a duplicate column with the transformed data and group by that.

Nice idea - thanks for this. Using rowGroup.dataSrc as a function would provide this ability. We'll add that ability and write up a blog post about this early in the new year.

For the record, this could use https://datatables.net/reference/option/columns.render, maybe this extension could use a group option from there.

Custom value: It is possible for plug-ins such as Responsive (through its responsive.orthogonal option) and Buttons (buttons.exportData()) to request custom data types specified by the developer. This can be useful in cases where you want send certain data to a particular extension.

In order to use this we would have to call https://datatables.net/reference/api/cell().render()
