我有一个表，其中附有行工厂，以对某些行进行着色。问题在于，上下滚动表后，行只会更改颜色。表格启动时我该怎么做才能显示背景色？
此处有一个视频：https://screencast-o-matic.com/watch/cFQYlEqPSv
ObservableList<SupplierProductOTIF> orderData = FXCollections.observableArrayList();
orderTable.setRowFactory(row -> new TableRow<SupplierProductOTIF>() {
@Override
public void updateItem(SupplierProductOTIF item, boolean empty) {
super.updateItem(item, empty);
if (item == null || empty) {
setStyle("");
} else {
if (item.isException()) {
//We apply now the changes in all the cells of the row
for (int i = 0; i < getChildren().size(); i++) {
((Labeled) getChildren().get(i)).setStyle("-fx-background-color: rgba(255, 0, 0, .25);");
}
} else if (item.getQtyToOrder() > 0) {
//We apply now the changes in all the cells of the row
for (int i = 0; i < getChildren().size(); i++) {
((Labeled) getChildren().get(i)).setStyle("-fx-background-color: rgba(0, 255, 0, .25);");
}
} else {
for (int i = 0; i < getChildren().size(); i++) {
((Labeled) getChildren().get(i)).setStyle("");
}
setStyle("");
}
}
}
});
orderTable.setItems(orderData);
for (SupplierProductOTIF product : supplier.getOtifSupplierData()) {
if(product.getQtyToOrder() > 0 || product.isException()) {
orderData.add(0, product);
} else {
orderData.add(product);
}
}
编辑：这是我班上的完整代码
