Create and Download an Excel file using SheetJS in a JavaScript function

I need a person to create an Excel file from an array using SheetJS inside a JavaScript function just like the video at [login to view URL] I want it all call from a function. I will assign my own method of calling the function. I do need one item added to this video in that I need to control the output column widths. I've attached what the output should look like and the data array. The final code will go into my Vue program that is already setup to handle SheetJS. NO PHP and no jQuery is to be used. You can use HTML, JavaScript, SheetJS and filesaver
