You could create your own table menu. You're better off with a custom menu anyway, since the in-built menu e. g. closes each time you click on a button. Unfortunately there is no getter for the context menu, so you'll have to find access to it either via reflection or a lookup.
I created a gist for a custom menu via the reflection and the lookup mechanism. Maybe it's of help for you.
The relevant part for you would be
CheckBox cb = new CheckBox(tableColumn.getText());
where you set the menu item to the text of your preferrence, i. e. the text of your labels.
Here's a lookup version for TreeTableView:
