How Do I Work By Linking the Cell To the Cell In the iCloud Copy of Numbers?

Explained to us in the link: https://www.youtube.com/watch?v=pld3t8wFiTU
How to link the same cell to the cell in another table. But it is not available in the iCloud version. It does not work in the same way as on the desktop.
I would be grateful if you give me the reason.
My field of work sometimes necessitates dealing with iCloud in the number and other Mac programs using Windows devices.
I specialize in spreadsheets.
I want to know why there is no same feature and method in iCloud.
