A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hello Jerby,
I am an independent advisor and Microsoft office user.
Allow me to kindly ask that you simulate a few samples so that we can understand the point of failure.
Close all your excel workbooks then open a new workbook. Put some raw data [ don't copy-paste from another location] then apply cell borders. Copy that range and paste it to Gmail and see how it works.
Try on another sheet if you apply tables and copy-paste to Gmail if the behavior is the same.
Let me know how it goes.
All the best.
