I currently ship a web app, which among many things contains an 'excel grid clone'. My earlier team collaborators, who by now have jumped ship to other greener pastures, styled the grid in 'that modern way', so on a huge ultra-HD resolution monitor, you could view maybe 9 columns at a time, if you squeezed them a bit :-/. Soon after the CSS guru was gone, I changed that grid CSS to instead honor the spirit of Excel, and it is now possible to view more than 9 columns of data, and more than 7 rows :-/. I still in vain try to fathom the mindset that would make you turn 'excel' into a bottleship-scrolling-microscope-hell.
