if cell value is array use next row

[nattyluke]

exceljs is so cool because its easy to use, has nice documentation and is very powerfull. Thank you!
I have to map (more precise: reduce) my row(s) to several rows .
But wouldn't it be nice that if my cell value is an array, to just add the first value and then use the next row to add the next value and so on.
Best would be to automagically merge cells which have just one value.
