[FIXED] Simpler method for defining tableview data with many columns?

Issue

I'll try to explain this as best I can. I've only started looking into JavaFX for the first time this past week. I'm still grasping how to use PropertyValueFactory and SimpleStringProperty, but I make it work. Now, if I have 20 columns that's 20 get/set methods I'd need to write. Not a huge issue, but tedious and seems long-winded to me.

Is there a way I can have all the columns call the same method for data retrieval but pass in a variable? Like either a String or an enum? So the object in my TableView's ObservableList would have a method like:

class TableObject{
    public String getTableElement(String key){ 
        return this.data.get(key);
    }
}

Hopefully that makes sense, I wasn't quite sure how to word this question.

Solution

Implement your own Callback and replace the PropertyValueFactory.

private static TableColumn<TableObject, String> createColumn(String name, final String key) {
    TableColumn<TableObject, String> column = new TableColumn<>(name);
    column.setCellValueFactory(cd -> new SimpleStringProperty(cd.getValue().getTableElement(key)));
    return column;
}
