Implementing the rows and columns yourself means inventing your own duplicate API for managing them, but it’s likely not a lot of code, assuming you only need textual editing of one cell at a time (and can therefore use a single re-usable, movable text field for the editing).

I hadn't considered asking my delegate for text and images directly. That could be a simpler way to do things - I will look into it.
The functionality that I'm missing is:
- Granularity of selection. For example single or multiple disconnected cells. NSTableView only gives me row or column.
- Scrollable floating headers on both axis. This I did sort-of manage with NSTableView by styling the first column to look like a header, but it was not great.
Maybe I will have another look at digging into NSTableView again.
