I'm here to help. Thanks for the screenshot of your screen.
It looks like you're trying to view your Variants on a wider screen. Is that right? If so, I'm curious where you're viewing your Variants page here. Is this on mobile, or on a desktop? Let me know and we can work on some solutions together!
Thanks for waiting, I was digging into this for you with the information you've provided and tried to replicate this on my test store. Here is a screenshot from my test store of what my Variants look like in my Variants section on my product's page:
I am not able to replicate what you're experiencing. I am curious, are you using any apps on your store, or any plugins on your browser? How did you get the view of the variants that you have in your screenshot? If you could let me know, that would help me troubleshoot the display for you.
Is there any way I can just expand this column so I can actually see all fields and not have to jump around with TAB?
For UI's you can try to use horizontal scrolling, either with a mouse with a tilt function, a touchscreen, mouse shortcuts(shift+mousewheel), or the keyboard shortcuts(which will vary by device and setup)

I am not using any plugins that affect the back end of the shop. You cannot replicate this because you dont have as many columns as I do for your variants.
I have a total of 3 columns (Grips, Style, Price) plus the quantity, and SKU column.
