Question

我只想使用fxml在表视图中添加测试数据。我不知道该怎么办！

就是这样。

例如，我使用fxml在组合框中插入数据。这样。

仅使用fxml生成。例如

<ComboBox prefHeight="25.0" prefWidth="193.0" promptText="Select your best language" visibleRowCount="5">
    <items>
        <FXCollections fx:factory="observableArrayList">
            <String fx:value="java" />
            <String fx:value="javafx" />
            <String fx:value="css" />
            <String fx:value="fxml" />
            <String fx:value="c++" />
        </FXCollections>
    </items>
</ComboBox>

我也使用fxml添加列表视图。这样。

使用fxml：

<ListView maxHeight="-Infinity" maxWidth="-Infinity" prefHeight="200.0" prefWidth="200.0" >
   <items>
        <FXCollections fx:factory="observableArrayList">
            <String fx:value="java" />
            <String fx:value="javafx" />
            <String fx:value="css" />
            <String fx:value="fxml" />
            <String fx:value="c++" />
            <String fx:value="visual basic" />
            <String fx:value="groovy" />
            <String fx:value="coltion" />
        </FXCollections>
    </items>
</ListView>

但是如何在table-view中添加数据。仅使用fxml。我想要这样做，以便可以在scene-builder预览中实时查看。

这里是一个例子。来自here的代码。

        <TableView fx:id="tableView" GridPane.columnIndex="0" GridPane.rowIndex="1">
            <columns>
                <TableColumn text="First Name">
                    <cellValueFactory>
                        <PropertyValueFactory property="firstName" />
                    </cellValueFactory>
                </TableColumn>
                <TableColumn text="Last Name">
                    <cellValueFactory>
                        <PropertyValueFactory property="lastName" />
                    </cellValueFactory>
                </TableColumn>
                <TableColumn text="Email Address">

                        <PropertyValueFactory property="email" />
                    </cellValueFactory>
                </TableColumn>
            </columns>
            <items>
                <FXCollections fx:factory="observableArrayList">
                    <Person firstName="Jacob" lastName="Smith"
                            email="jacob.smith@example.com"/>
                    <Person firstName="Isabella" lastName="Johnson"
                            email="isabella.johnson@example.com"/>
                    <Person firstName="Ethan" lastName="Williams"
                            email="ethan.williams@example.com"/>
                    <Person firstName="Emma" lastName="Jones"
                            email="emma.jones@example.com"/>
                    <Person firstName="Michael" lastName="Brown"
                            email="michael.brown@example.com"/>
                </FXCollections>
            </items>
        </TableView>

如何仅使用fxml（不使用任何Java代码）在表视图中添加数据？
