Hi @Halim,
You have two possibilities, depending on the column you want to delete:
- if it’s a “real column”, ie it’s 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 it’s a “virtual column” (with a blue pen in your editor) : click on the blue pen, then click on “Delete”.
Cheers
