A new Grist table defaults with 3 columns. If I paste a table with more than 3 columns, Grist should add the additional columns I’m pasting.
I agreed that this would be a useful feature. Based on this post and Rename Header using a Row, it sounds like you’re importing existing data from elsewhere. Have you tried importing from a file such as CSV or Excel? That should fill in all the columns.
Yes, and I don’t have issues when importing
