Please give us the ability to copy columns to other tables.
I’m not just talking about column values from a column, I’m talking about the entire column(s), including their conditional formatting, formulas, types and such to other tables.
This is useful for me as I have a page with multiple tables for different groups, and when I want to add a new column for all tables, I have to do it for each table individually including all the formatting and such which is extremely tedious.
I think what Pablo_DV and Piet_StrydomCommunity Champion are saying is that it seems you are constructing your doc with spreadsheet principals in mind (Google Sheets/Excel) when Coda is not designed to work that way.
Coda works more like a database and what they are suggesting is to approach your issue with database best practices in mind instead of spreadsheet best practices. I learned the hard way that it will make your life easier when following this approach.
