                <TableView fx:id="tableView" VBox.vgrow="ALWAYS">
                    <columns>

                        <TableColumn fx:id="date" minWidth="0.0" prefWidth="500.0" text="Date" />
                    </columns>
                </TableView>
            </children>
        </VBox>

    </children>
</AnchorPane>

我希望图像显示在右上角但是它没有位于那里我试图用“layoutX和layoutY”改变X和Y坐标，但这似乎不起作用。

不同的Pane有不同的选择孩子位置的方式。

如果是AnchorPane，则可以使用锚点属性完成与右上角的对齐。这些属性控制父AnchorPane的子节点到窗格边框的距离。

以下示例将Rectangle放在AnchorPane的右上角：

<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml/1">
    <children>
        <Rectangle width="50" height="50" AnchorPane.topAnchor="0" AnchorPane.rightAnchor="0" />
    </children>
</AnchorPane>

您也可以将ImageView放在fxml的右上方。
