How does Axlx work?

Question

Ruby on Rails

I'm trying to figure out the Axlsx gem and so far I'm at an impasse. Hope the gurus can help.
there are two arrays with numbers, you need to implement the creation of an Excel file and filling two columns with data from these arrays - The first column is data from the first array and the second is data from the second array. How can this be done with the Axlsx gem?
