设置JavaFX TableView单元的字体颜色？

设置JavaFX TableView单元的字体颜色？

您需要覆盖CellFactory。

仅第三列的部分代码：

    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);         }     } };        }    });
