Lightning Datatable is one of the more powerful base Lightning Web Components. This component allows developer to display multiple rows of objects with dynamically formatted columns for a variety of data types. Lightning Datatable’s action column allows a developer to specify a list of actions which are available for the user to select. This is great for most use cases, but the actions are defined as a constant, which means that every row must share the same actions.
Here is a simple demonstration of a lightning datatable with dynamic row actions
Unfortunately there is one minor limitation to this implementation. If a row has no actions, the drop-down arrow will still show and clicking it will display an empty list.
