i am trying to create a table with two columns. i am using the scene builder included in netbeans 7.2. in all the examples i have seen all you need to do is drag the table column to the table and it will take the full size, this is not true in my case. this is the fxml file generated by the scene builder. just to be clear i am not changing the table properties from the java.

the fxml:

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.net.*?>
<?import java.util.*?>
<?import javafx.geometry.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.image.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.text.*?>

更新

JavaFX 2.2+ 版本中的新功能使此答案在与 FXML 文档一起应用时已过时。

一个基于 FXML 的解决方案，它使用新的 FXML 功能允许通过 FXML 设置列大小：FXML set TableView column resize policy。

<TableView fx:id="tableView" layoutX="110.0" layoutY="78.0" prefHeight="200.0" prefWidth="396.0">
    <columnResizePolicy><TableView fx:constant="CONSTRAINED_RESIZE_POLICY"/></columnResizePolicy>
    <columns>
        <TableColumn prefWidth="75.0" text="Column X" />
        <TableColumn prefWidth="75.0" text="Column X" />
    </columns>
</TableView>

如果您不使用 FXML，TableView 的调整大小策略仍然可以通过此答案中定义的代码设置：

tableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);

在您的 FXML 中，您已将表的首选宽度定义为 837，将每列的首选宽度定义为 75。默认情况下，JavaFX 列大小调整策略将保持列的首选宽度。除非您设置新的列大小调整策略或将所有列的首选宽度之和设置为表格宽度，否则您不会让表格列填满整个表格的宽度。

JavaFX 确实提供了一种修改默认列大小调整策略的机制。通过将列调整大小策略设置为CONSTRAINED_RESIZE_POLICY，每列的宽度总和将被限制为填充 tableview 的宽度 - 即使调整了 tableview 的大小或调整了单个列的大小。这可能是您想要的行为。

虽然可能有一种方法可以在 FXML 的 tableView 上设置 CONSTRAINED_RESIZE_POLICY，但我不知道有一种方法（尽管我在 fxml 方面的技能还很初级 - 所以也许更知情的人可以使用纯 fxml 完成配置）。

您可以做的是为您的 fxml 文件定义一个控制器，然后在控制器中配置调整大小策略。以下代码演示了一个完整的示例（针对 JavaFX 2.2b17 预览版编写）。

FXML 文件：

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>

<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml" fx:controller="tableview.TableViewController">
  <children>
    <TableView fx:id="tableView" layoutX="110.0" layoutY="78.0" prefHeight="200.0" prefWidth="396.0">
      <columns>
        <TableColumn prefWidth="75.0" text="Column X" />
        <TableColumn prefWidth="75.0" text="Column X" />
      </columns>
    </TableView>
  </children>
</AnchorPane>

控制器类：

package tableview;

import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.TableView;

/* controller class for the tableview fxml definition */
public class TableViewController implements Initializable {
  @FXML //  fx:id="tableView"
  private TableView<?> tableView; // Value injected by FXMLLoader

  @Override // This method is called by the FXMLLoader when initialization is complete
  public void initialize(URL fxmlFileLocation, ResourceBundle resources) {
    assert tableView != null : "fx:id=\"tableView\" was not injected: check your FXML file 'tableview.fxml'.";

    // initialize your logic here: all @FXML variables will have been injected
    tableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);
  }
}

应用类：

package tableview;

import java.io.IOException;
import java.net.URL;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;

/** Main application class for tableview fxml demo application */
public class TableViewApplication extends Application {
  public static void main(String[] args) { launch(args); }
  @Override public void start(Stage stage) throws IOException {
    AnchorPane layout = FXMLLoader.load(
      new URL(TableViewApplication.class.getResource("tableview.fxml").toExternalForm())
    );
    stage.setScene(new Scene(layout));
    stage.show();
  }
}

如果您使用 JavaFX GUI 构建器“SceneBuilder 2.0” - 使用 TableView 属性ColumnResizePolicy “约束调整大小”值。

目前无法从 FXML设置CONSTRAINED_RESIZE_POLICYa ：tableView
