I'm trying to build an app that we're going to use for invoicing. What I need is a 5x8 form (5 columns, 8 rows) that pushes data to a SharePoint list. I feel like I must be missing something easy here and I need some suggestions. The SharePoint connectivity part is already working, it's the layout of the form that's off.
1. With "Snap To" columns enabled, it'll only let me pick 4 or 6 columns for the layout. All I really need is 5 but that's fine, I can work with 6.
2. When I pick 6 columns, this is what it does (see pic). I'm by no means a PowerApps expert at this point but that looks like 3 columns to me.
3. What's with all the white space / why is it so difficult to move fields around and just make this thing conform to the way I want it to look?!?

All I'm ultimately looking for is to have a tightly spaced grid where users can enter this data, and it goes back to my SharePoint list. Why is this all so clunky / what am I missing? Is the built in "Form" feature not the ideal way to be doing this?
Here is an mockup of what I'm trying to get this to look like.
