In posts like this, can you provide more information about your use case for these features? What kind of application do you have? What do your users need to do? How does not having this impact the business? What kind of work around have you implemented?
There are many possible solutions to add sorting / filtering to editable grids, and understanding more about your use case could help us prioritize which solution would be best.
Like others have mentioned above, there may also be tradeoffs with a feature like this that could make it more difficult to validate or edit data, so there may also be current features that could still meet your use case (depending on why you need to be able to sort / filter).
