What it means
Column actions let the menu insert or remove columns around the current selection.
Interaction guide
Columns data grid documentation
Add and remove columns.
When to use it
Use this when users need to expand or shrink a block of columns in place. Keep the page focused on column insertion and column removal only.
Implementation notes
Start with `api.buildContextMenuConfig({ includeColumns: true })`. Use extra column actions only when you need a product-specific remove flow.
Relevant API
Start with contextMenu.enabled, contextMenu.items, contextMenu.closeOnSelect, contextMenu.renderMenu, contextMenu.onOpen, contextMenu.onClose, contextMenu.onAction, contextMenu.handlers. Open the live API reference for types and defaults.
