Hello Gabriel, and thanks for the pointers, with them I managed to complete the task of controlling row appearance! (For those who may wonder; the resulting "status_up" and "status_down" render a row white with no spinner (final state), "status_unknown" renders a row pale yellow with spinner.)
I actually had looked at the calculate_row_status() and get_row_status_class() functions of class DataTable before, but I did not connect them with row state, probably due to the status naming of True, False, None and "status_up", "status_down", "status_unknown". I expected to find something to describe state machine state, like final (white row) and intermediate states (yellow row).
