It would be extremely helpful to have the ability to quickly select an entire column by clicking its header (or by using shift-click to select a range) and then copy its contents using standard keyboard shortcuts like Ctrl+C/Ctrl+V. This would allow users to easily paste the data into a new column or even another table, much like how it’s done in platforms such as Airtable. Currently, the inability to seamlessly copy and paste full columns feels like a significant limitation compared to similar tools, and adding this feature would greatly enhance workflow efficiency.
