JavaFX 2: TableView

JavaFX provide API of TableView, TableColumn, and TableCell to help creating tables. You can populate a table by implementing the data model and by applying a cell factory.

The table classes provide built-in capabilities to sort data in columns and to resize columns when necessary.

It's a example of JavaFX 2 TableView.



Please note that the setCellValueFactory() method specifies a cell factory for each column. It uses the "fieldMonth", "fieldValue" properties of the table columns as references to the corresponding methods of the Record class. It assume that there are callback method named getFieldMonth() and getFieldValue() in Record class. Remark - if you name it getfieldMonth() and getfieldValue(); it will not work!
