Hi,
If you want to display like tree table structure go with Tree table. But as you mentioned it is not responsive.
Else if you have a static node structure (All the parents should contains equal level of drill level). You can use list with panel.
You can set the panel like expandable true, inside load the list. again do the same till you reach the least node. But this will work only for static structure, Not a dynamic structure.
Thank you ,
