I am trying to get output that would look like this:
The MWE I attached works well for equations with non-nested fractions or without fractions.
The problem arises when I have equations with nested fractions. The text on the left is offset compared to the part of the equation before =. Is there a way to align "Calculation" with "ROIC Ticker" at their baseline?
