ClassCastException from DoubleStringConverter

[Andrew Munn]

And if I change the column to String I get this:

myColumn.setCellFactory(TextFieldTableCell.forTableColumn());

Exception in thread "JavaFX Application Thread" java.lang.ClassCastException: class java.lang.Integer cannot be cast to 
class java.lang.String (java.lang.Integer and java.lang.String are in module java.base of loader 'bootstrap')
