I expressed the expression of the formula for the limit as a string.
PasteButton[Style["\!\(\*UnderscriptBox[\(\[Limit]\), \(n \[Rule] \\[Infinity]\)]\)f[n]", 12], Unevaluated[Limit[SelectionPlaceholder[expr], Placeholder[var] -> Placeholder[value]]], ImageSize -> {70, 35}, BaselinePosition -> Center]
I need to insert this inside Column & Row.
Column[{Row[{PasteButton[ Style["\!\(\*UnderscriptBox[\(\[Limit]\), \(n \[Rule] \\[Infinity]\)]\)f[n]", 12],
Unevaluated[ Limit[SelectionPlaceholder[expr], Placeholder[var] -> Placeholder[value]]], ImageSize -> {70, 35}, BaselinePosition -> Center]}]}]
In this case, the form of the equation is not natural. Is there a way to express it as well as in the first place?
