我有应用程序布局：

由于编写代码，我得到了

问题：如何删除带有关闭标签的第一行，并仅保留布局上的原样？
项目结构：

有多种方法可以执行此操作，具体取决于要添加到应用程序/布局中的通用性。
但是最重要的是，您似乎通过混用TabPane和Tab来犯错。虽然第一个是容器，但是第二个对应于您可能拥有的每个选项卡。通常，您有一个TabPane，其中包含许多Tab（即使不是必须的）。
一种解决方案可能是通过执行此操作（阅读评论）来修改方法showTab
private void showTab() {
try {
// Tab 1 loader
FXMLLoader loaderTab1 = new FXMLLoader(Main.class.getResource("Tab1.fxml"));
// Tab 2 loader
FXMLLoader loaderTab2 = new FXMLLoader(Main.class.getResource("Tab2.fxml"));
TabPane tabPane = new TabPane();
// Remove the 4 following lines, Tabs are already declared in FXML
//Tab tab1 = new Tab();
//Tab tab2 = new Tab();
//tab1.setContent(loaderTab1.load());
//tab2.setContent(loaderTab2.load());
Tab tab1 = loaderTab1.load();
Tab tab2 = loaderTab2.load();
tabPane.getTabs().addAll(tab1,tab2);
rootLayout.setCenter(tabPane);
} catch (IOException e){
e.printStackTrace();
}
}
并更改您的FXML文件，如下所示（删除了TabPane和tabs标签）：
<Tab xmlns="http://javafx.com/javafx/10.0.1" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Tab1Controller" text="Tab1">
<content>
<SplitPane dividerPositions="0.29797979797979796" prefHeight="160.0" prefWidth="200.0">
<items>
<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="160.0" prefWidth="100.0">
<children>
<TableView fixedCellSize="1.0" layoutX="-12.0" layoutY="27.0" prefHeight="371.0" prefWidth="176.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<columns>
<TableColumn prefWidth="75.0" text="C1" />
<TableColumn prefWidth="75.0" text="C2" />
</columns>

<TableView fx:constant="CONSTRAINED_RESIZE_POLICY" />
</columnResizePolicy>
