Hi @Halim,
You have two possibilities, depending on the column you want to delete:
- if itโs a โreal columnโ, ie itโs one you have on your Sheets (with a dark pen in your editor) : remove it from your sheets, then go in your editor in Data/your table/view Column/Regenerate Structure
- if itโs a โvirtual columnโ (with a blue pen in your editor) : click on the blue pen, then click on โDeleteโ.
Cheers
