Not sure how your row's columns look like and what you want to show when but if you only need the data of 1 of the columns of th row just simply use this data entry then for your needs?
e.g. the row got 10 columns but only the data.mapId is needed.
No matter what was selected then just use selectedData.mapId in the selectedCallback function to populate the entries of list2 and list3.
It's only difficult f you e.g. hot mapId, zoneId in your row, as 2 columns. And depending on your selected row BUT ALSO the selected column (mapId or zoneId) the list2 and list3 should update.
You maybe able to use the moc() function to get the control below the mouse/name of the column below the mouse, and in the selectedCallback check the colun below the mouse to get if it's mapId or zoneId.
