You can use a custom cell factory in this case, here is an example:

• I've created an FXML document that contains a TableView holding two TableColumns, one for the fullname and the second for the address of a Person instance.

• I've then set the cellFactory as follows:

  addressCol.setCellFactory(column->{
              return new TableCell() {
                  @Override
                  protected void updateItem(String item, boolean empty) {
                      super.updateItem(item, empty);
                      if(item==null || empty) {
                          setGraphic(null);
                      } else {
                          VBox vbox = new VBox();
                          List textList = Arrays.asList(item.split("\n"));
                          String[] colors = {"#3E50B4", "#FF3F80", "#727272"};
                          int colorCount = colors.length;
                          for(int i=0;i

Now this is just an example where I've used a VBox containing a bunch of Label instances (one for each line), and I've hard coded the colors, you can use whatever you like, for example, you can try a TextFlow with Text nodes and you can also use CSS Style classes.

Here is the full example code:

TableViewExample.fxml

Person.java

public class Person {

    private String fullname, address;

    public Person() {}

    public Person(String fullname, String address) {
        this.fullname = fullname;
        this.address = address;
    }

    public String getFullname() {
        return fullname;
    }

    public void setFullname(String fullname) {
        this.fullname = fullname;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

        persons.addAll(p1, p2);
        fullnameCol.setCellValueFactory(new PropertyValueFactory("fullname"));
        addressCol.setCellValueFactory(new PropertyValueFactory("address"));

        addressCol.setCellFactory(column->{
            return new TableCell() {
                @Override
                protected void updateItem(String item, boolean empty) {
                    super.updateItem(item, empty);
                    if(item==null || empty) {
                        setGraphic(null);
                    } else {
                        VBox vbox = new VBox();
                        List textList = Arrays.asList(item.split("\n"));
                        String[] colors = {"#3E50B4", "#FF3F80", "#727272"};
                        int colorCount = colors.length;
                        for(int i=0;i

I hope this helps...
