I was working with Datatable tooltips and ran into the same issue that someone also had: tooltips didn’t work, unless I added tooltip: true to the table definition.
I think that if a column has a tooltip property, then Webix should honor that, an display tooltips for that column - without requiring the global tooltip property at the table level.
The problem with the table-level tooltip property is that it enables tooltips for ALL cells. I a table with many cell and I want only one tooltip:
I’m not sure, but if we do change the behaviour, there can be users that will need to define tooltip:true for every single column instead of just providing a global setting, which also seems cumbersome… )
