Description
I am using powerfx on premise with my own application. I have written some extension methods, but can't get an extension method up and running that returns a tablevalue. I want something like "LoadCSV(Path)" to be callable from powerfx formula. I asked copilot, tried various things. The main point seems to be that the tablevalue class is abstract. Has somebody done something similar and can me provide a sample or point me in the right direction? Any help would be appreciated , thank you.
Best Regards,
Stefan

Research direction
The issue mentions custom extension methods, the abstract TableValue class, and a desired LoadCSV(Path) formula function, but no repository files or tests. Start by locating the extension-method registration and TableValue APIs; done would be a documented, working sample showing how a table-returning method can be called from a Power Fx formula.
