JavaFX tableview隐藏选定行

在我的JavaFX应用程序中，我试图在tableview中隐藏选定的行。我使用CSS如下

.hideRow
{
     -fx-cell-size: 0px;
     -fx-border-width: 0;
}

我使用下面的一行工厂来实现同样的目标

import java.util.Collections;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.collections.FXCollections;
import javafx.collections.ListChangeListener;
import javafx.collections.ObservableList;
import javafx.event.EventHandler;
import javafx.scene.control.TableRow;
import javafx.scene.control.TableView;
import javafx.scene.input.ClipboardContent;
import javafx.scene.input.DataFormat;
import javafx.scene.input.DragEvent;
import javafx.scene.input.Dragboard;
import javafx.scene.input.MouseButton;
import javafx.scene.input.MouseEvent;
import javafx.scene.input.TransferMode;
import javafx.util.Callback;

我宣布该行为工厂

StyleChangingRowFactory  rowFactory = new StyleChangingRowFactory<>("hideRow");

---

问题是当我隐藏所选行时。它还在表视图中隐藏一些其他行。请帮我解决这个问题。

你能说明你是如何使用行工厂的，以及你是如何操作它的

styledrovindices

列表的吗？@James_D在我的控制器中，我声明行工厂为StyleChangingRowFactory rowFactory=new StyleChangingRowFactory（“hideRow”）；私有void hidePressed（）{rowFactory.getStyledRowIndices（）.addAll（cfiTableView.getSelectionModel（）.GetSelectedDices（））；}从该列表中从何处删除值？你能编辑这个问题并添加更多细节吗？@James_D我现在更新了这个问题。@user2971296，你能创建一个并用它更新你的问题吗？

private void hidePressed() {
        rowFactory.getHiddenRowIndices().addAll(cfiTableView.getSelectionModel().getSelectedIndices());
    }

    private void unHidePressed() {
        rowFactory.getHiddenRowIndices().removeAll(cfiTableView.getSelectionModel().getSelectedIndices());
    }
