JS linways/table-to-excel how to add formulas

Question

So I'am building excel files with @linways\table-to-excel (https://www.npmjs.com/package/@linways/table-to-excel)

But when I try to insert a simple formula the file with cell like this:

However, when I click formula field and press enter, then it recalculates and shows valid value.

My excel is configured to have automatic calculation.

Is there any way fix it somehow? Or else, is there a way to add some kind of newline symbol to use in this library?
