[FIXED] Setting font color of JavaFX TableView Cells?

Issue

In my Java Desktop Application I have a JavaFX Table with 3 columns. I want to set the font color of the 3rd column to red. I have not been able to set the font color of the Tableb at all. I looked into CSS and I did not find anything. Is there a way to do it with CSS? I also looked for setFont() with the hope of setting it that way. Nothing there. I could not even figure a way to set something on a certain cell.

TableView<TableData> myTable = new TableView<TableData>();
ObservableList<TableData> myTableData = FXCollections.observableArreyList(
    new TableData("data", "data", "data"),
    new TableData("data", "data", "data"));

TableColumn firstColumn = new TableColumn("First Column");
firstColumn.setProperty("one");
TableColumn secondColumn = new TableColumn("Second Column");
secondColumn .setProperty("two");
TableColumn thirdColumn = new TableColumn("Third Column");
thirdColumn .setProperty("three");

myTable.setItems(myTableData);
myTable.getColumns.addAll(firstColumn, secondColumn, thirdColumn);

How can I accomplish this? How can I set to font color? Any help will be appreciated.

Solution

You need to override the CellFactory.

Partial code just of the third column:

    TableColumn thirdColumn = new TableColumn("Third Column");  
    thirdColumn.setCellValueFactory(new PropertyValueFactory<TableData,String>("three"));

    // ** The TableCell class has the method setTextFill(Paint p) that you 
    // ** need to override the text color
    //   To obtain the TableCell we need to replace the Default CellFactory 
    //   with one that returns a new TableCell instance, 
    //   and @Override the updateItem(String item, boolean empty) method.
    //
    thirdColumn.setCellFactory(new Callback<TableColumn, TableCell>() {
        public TableCell call(TableColumn param) {
            return new TableCell<TableData, String>() {

                @Override
                public void updateItem(String item, boolean empty) {
                    super.updateItem(item, empty);
                    if (!isEmpty()) {
                        this.setTextFill(Color.RED);
                        // Get fancy and change color based on data
                        if(item.contains("@")) 
                            this.setTextFill(Color.BLUEVIOLET);
                        setText(item);
                    }
                }
            };
        }
    });
