Hi,
you did nothing wrong (beside the action should be a callback function) but ui-table uses the now outdated version 4.4.1 of tabulator which does not have the menue feature. (If you use the docs make shure that you are on version 4.4)
There is already an issue posted to update to 5.0 but I have no time in the near feature to contribute this (My first try revealed a lot of API changes and new problems).
I'm using the ui-context menue node to do so and even if it brings more effort you get Node-RED in control of the context menu. The [post you already found is still valid]. And there is a cellCotext and a rowContext callback too. ([Announce] node-red-contrib-ui-contextmenu - #55 by Christian-Me)
Here is a partial flow to handle the ui-context-menu. It works together with the callback described in the post above
I'll could not promise anything but I'm still willing to do the upgrade to 5.x - but there are so many possibilities to break things - so I'm a little bit afraid to do this in a rush.
