Thank you. I remember I had a look at that. Made a quick look now at PrimeVue treetable [0], to compare it to MUI datagrid [1].

There seems to be a wide gap in feature scope and depth. For example, column grouping in [0] seems to be not available (it is in PrimeVue datagrid, but that misses support for data hierarchy).
