What it means
Merge actions turn a range into one visual block and then restore it again.
Interaction guide
Show merge and unmerge.
Merge actions turn a range into one visual block and then restore it again.
Use this when repeated labels should collapse into a single cell. Keep the page focused on merge and unmerge only.
Start with `api.buildContextMenuConfig({ includeMerge: true })`. Keep the merge page paired with spanning so the selected block has something to merge.
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.
