I bet you can't help me build a feature to add columns to a kanban table

Hey guys :laughing: :laughing:. Hope you can help me, this project is very important to me. I am using a template for a Kanban table from the marketplace, and so far its working fine, but for some reason the creator didn’t build a system for adding columns, only for adding tasks (see pic 1), which is not ideal. I want it to scroll to the left and to add as many columns as the user wants, like trello yk? So I basically want another button in the home page similar to the “add task” button (see pic 2) but instead of adding a row, it adds a column. Here is the link for the template, and pictures to help you understand my situation. I appreciate any help I can get. Thank you!!
