This sample uses a FlowPane so that it works with JavaFX 2.2. Future version of JavaFX will add a TextFlow node, which would be the preferred way to to multi-word colorization in JavaFX.

Can we have a multi-colored text inside the tableview cell? In swing I did that using html font tag but in JavaFx that doesn't work sample: http://s4.postimg.org/ck8sv41sd/help_aid.jpg

Yes takasurazeem, create the TextFlow in the update method of a TableCell generated by a TableView CellFactory. If you have further questions, ask them on StackOveflow under the JavaFX tag please.

error in Java 8

Yes haucongle, when I run the application with Java 8u72, the first image in the list is not displayed, but the others are. How bizarre. It used to work fine in earlier versions. I updated the code and resources used in the gist as they were pointing to some images that weren't existing on the web, but even then, it still doesn't work right anymore and the first image is not displayed. There is perhaps some bug introduced in Java 8 or something in the program that was always wrong and was exposed by the Java 8 implementation (I don't really know what is going wrong).

Anyway, the sample application is now pretty obsolete, and the appropriate way to do this in Java 8 would be to use the new TextFlow control that was added in Java 8, instead of using a FlowPane to contain styled text (as has been demonstrated in this application).
