Request extension by paying - TableView

Hi everyone, I need an extension and I’m looking for someone who develops extensions on demand.
The extension I am looking for is already present, made by a great creator, but I think he is committed to something else.
The extension I’m talking about is called @Ken 's tableview and it’s fantastic for me, ideal for the type of app I want to make.
I’ve already asked @Ken for some changes, but I think he’s busy with something else, and that’s okay, but now, in my current app, which I’ve been working on for a year, I need some features.
This extension, for what I need, lacks the events and properties that I will explain later. I use it to manipulate data archives and create a management app interface.
If anyone knows what I’m talking about and thinks they can help me, I ask you to write me here. Thank you.

What features you want to add to extension?
Can you please explain bit more about that?
Second thing I don't know exactly but extension is not opensource so it would be difficult to add new features for other developer.

I post a small video of what I am making. The screen you see is all dynamically created with dynamic components and with tableview, you may notice some bugs because I am correcting some behaviors, but my main problem is being able to simulate some events of the tableview, the current bugs do not bother me. The intent is to create an excel-type screen that manages a database with functionalities and I'm succeeding, but I miss being able to manage certain events.

Currently this component displays the data that is passed to it as a DataString, showing it with rows and columns.
It has the methods of loading data and positioning on a given row.
I expose what it does not do and what I would need:

  1. Modification of a single grid cell, to do it now I modify the data and then reload it on the tableview.
  2. Positioning not only by row, but also by cell.
  3. Ability to assign a different color to the active cell (cell on which you have clicked or positioned by code).
  4. Ability to keep the header row fixed
  5. Possibility of being able to delete a row
  6. Possibility of managing lostFocus, gotFocus events per cell / row

Unfortunately, it seems to me that the extension is not open source, I asked @ken if he "released" it, but he doesn't connect frequently at this time.

have a look here CSV editor, help me to improve it
