I would prefer to work with the bound data, though.
I’m afraid I am thoroughly confused about adding rows by creating a row and adding nodes to the grid, vs. adding rows to the data source.
The latter is my preference, and it does work, but only for append and insert but not insert at top.
I had hoped I could manipulate the data source, as it is most convenient for e.g. update an array from a REST fetch, but only having partial luck with this. Works if I want to add to the end or middle, just not at the top.
