Hierarchical Data in Table or List

Summary:

Hello,

Our requirement is to build a table/list which will have hierarchical data (something similar to what we have in CPQ's line item grid). Can someone point me in the right direction on how to do this? I am aware of the "Detail Row with Tree Data" (https://www.oracle.com/webfolder/technetwork/jet/jetCookbook.html?component=table&demo=detailTable), but does it support a multi-level hierarchy?

Example screenshot of what we want to mimic:
