Current behavior
Datatable filter cannot be used with objects/arrays.
If i pass in a object (or array of objects), for example {name: 'test', id: 1} I would like to be able to have the column filtered by name. Because in a custom column template i use the name field as a display value but on rowclick i need to get the id to further doSomething() with the id. Therefor the object as data.

In some cases i may have an array of items or array of objects:
[1,2,3,4,5] or [{role: 'test', id: 1},{role: 'test2', id: 2}]

Or when using a range filter component (like from year to year).

Expected behavior
Can specify custom filter method similar to sortFunction.

p-dataTable is deprecated and will be removed in favor of the new p-table (aka TurboTable) of 5.1.0 so closing the issue. Please try the new p-table once 5.1.0 is released.

Can we reopen this? still not available in the new TurboTable.
I would also like this.
