The ability to create expanded hierarchical tables would be a great feature. I'll add an [example](https://tabulator.info/docs/5.5/tree) of such an implementation.

Thank you for your feedback. I was able to add the required constraint to the model (https://github.com/dirkschumacher/ompr/issues/259#issue-445883878). Here is the working code: ``` library(dplyr) library(ROI) library(ROI.plugin.symphony) library(ompr) library(ompr.roi) library(ROI.plugin.glpk) project_list...

The model generates the right solutions for my task. Perhaps I didn't describe the constraints quite correctly: ``` a + b + c + d + ... + n ==...

Your code works on this data, but I tried to add another group of interdependent projects (e and f) and the solution did not match my expectations. ``` project_list %...

> Your constraint says that projects 1:3, 5:6 are linked. Only one project of those 5 can be selected, so project 1 and project 4 which has no dependencies are...
