Add new Rows inside table at a position

Evening everybody. So I’m trying to create this UI with react-table. I got it up and running. What I’m trying to figure out is there’s four groups(scales,chords,songs,techniques) if I click on the plus depending which plus it is I want to add a new row under that groups names. So if I click on plus next to scales a new row should be added at the top of the scales group and if it’s songs a new row should be added at the top of the songs group. Anybody know if this is possible with react-table?
