Finding the Simplex tableau information

Question

I am trying to find the simplex tableau information by PySCIPopt wrapper. I called some methods to get the related information like scip.getLPColsData() and scip.getLPRowsData(). However, as the problem cannot throw any issue, it seems the function does not call into the SCIP.

Also to call methods in the solving process we still need to make their appropriate callbacks and I am not aware of which one of the callbacks should be implied. Please, see the modifiable MRE here.

Now, my questions are:

1. What is scip.getVars(transformed = True) meaning? and how can I get/make the transformed model?

2. Is it necessary to call some methods like SCIP_RESULT.DIDNOTRUN as it seems to be a flag?

3. Is there any illustrative example of how one can invoke such information from the solver?
