I found these examples:

Can a table row expand and close?
Basically I want to create a JavaFX table which I can expand in order to see more data. Is there any similar example written in JavaFX?
EDIT
So, after reworking the problem with tableView specifics, I (sort of) quickly hacked together this example. Keep in mind, I didn't use the animation mentioned in the original answer, although it would be easy enough to adapt, and I didn't replicate the provided example exactly at all, since I honestly, didn't have time. But this gives the basic accordion feel, where you would just need to spend time messing around with various width and height properties of different fields to achieve something that was exactly that. (in the handler you might want to even insert a row where the first column has a huge width and a nested table view to achieve sort of exactly what they were doing). again, this is with 1 column, and it shows the basics of adding a bit of added information on expansion, you could take this as far as you want:

Person.java:

public class Person {
private StringProperty firstName;

public Person(String firstName, String lastName) {
setFirstName(firstName);
setLastName(lastName);
}
public final void setFirstName(String value) { firstNameProperty().set(value); }
public final void setLastName(String value) { lastNameProperty().set(value); }
public String getFirstName() { return firstNameProperty().get(); }
public String getLastName() { return lastNameProperty().get(); }
public StringProperty firstNameProperty() {
if (firstName == null) firstName = new SimpleStringProperty(this, "firstName");
return firstName;
}
public StringProperty lastNameProperty() {
if (lastName == null) lastName = new SimpleStringProperty(this, "lastName");
return lastName;
}
}
Again, pardon the seemingly hackery of adding the various buttons with the named columns that do nothing, It just got super busy here so I borrowed the main table structure from :
original SO table dynamic row addition question
Who did a wonderful job of adding additional rows to a table.
again, if this is not at all what you need let me know, and I'll try to help as best I can.
