I feel like I’m going crazy. Multiple people I work with make “tables” by just outlining the cells.

I think I’m moderately skilled with excel. I can do most things I need to, but I’m entirely self taught. If someone needs something explained I usually suggest they ask someone else, because I’m never sure I’m doing things the correct way.

Multiple people I work with make a “table” by highlighting the cells they want and clicking all borders.

It has me questioning everything. I prefer tables, always. Am I wrong?
