Java SWT文本在gridlayout中未正确对齐

当我添加两个文本控件（dUsername和dPassword）时，它们没有正确对齐。请参阅随附的屏幕截图。 添加到组合旁边的两个文本控件应放在各自的标签标题下。但是，我无法找到不正确对齐的原因。如果我能得到任何关于这方面的建议，那将是非常有帮助的

 public void createControl(Composite Parent) {
            Composite container = new Composite(Parent, SWT.NULL);
            GridLayout layout = new GridLayout();
            container.setLayout(layout);
            layout.numColumns = 10;
            layout.verticalSpacing = 20;
            layout.horizontalSpacing = 15;

            GridData gd1 = new GridData(GridData.BEGINNING, GridData.BEGINNING, false, false, 1, 1);
            createLabelSection(container,gd1);
            getARowForEach(container,gd1);
        }
        private void getARowForEach(Composite container, GridData grid) {

            while (some condition) {
                String dString = (String) dIterator.next();
                addControls(dString, container, grid);
            }
        }

        private void addControls(String dvString, Composite container, GridData grid) {
            Button checkBox = setCheckBoxText(container, null);
            String dvLabel = dvString;

            getLabelCaption(container,dvLabel);

            Combo hostCombo = setComboText(container);
            Text dUsername = new Text(container, SWT.NONE);         
            Text dPassword = new Text(container, SWT.PASSWORD);

            }
            public Button setCheckBoxText(Composite container, Label label){
            Button checkBox = new Button(container, SWT.CHECK);
            GridData gd = new GridData(GridData.FILL, GridData.CENTER, true, false, 2, 1);
            checkBox.setLayoutData(gd);
            checkBox.setSelection(true);
            return checkBox;
        }

            public Label getLabelCaption(Composite container, String caption){
            Label label = new Label(container, SWT.NONE);
            GridData grid = new GridData(SWT.LEFT, SWT.TOP, false, false, 1, 1);
            label.setLayoutData(grid);
            label.setText(caption);
            return label;
        }
        public Combo setComboText(Composite container){
            Combo combo = new Combo(container, SWT.READ_ONLY);

            GridData gd = new GridData(GridData.FILL, GridData.CENTER, true, false, 2, 1);
            combo.setLayoutData(gd);
            .
            .     
            combo.select(0);
            return combo;
        }
        private void createLabelSection(Composite container,GridData grid ) {
            addLabel(container, grid, "some details");
            addLabel(container, grid, "some details");
            addLabel(container,  grid, "some details");
            addLabel(container, grid,"username");
            addLabel(container, grid, "password");
        }

我想您正在尝试使用控件模拟表格

您正试图将这些小部件完美地对齐，这使您自己变得复杂。只需创建一个包含所需列数的主容器（在屏幕截图中有5列），然后简单地创建一个向该容器添加行的方法

运行以下命令：

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Combo;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

    // ==================== 3. Static Methods ====================

    public static void main(final String[] args)
    {
        new Tester();
    }


    // ==================== 4. Constructors ====================

    private Tester()
    {
        final Display display = new Display();
        final Shell shell = new Shell(display);
        shell.setLayout(new GridLayout(1, false));

        createContents(shell);

        shell.pack();
        shell.open();
        while (!shell.isDisposed())
        {
            if (!display.readAndDispatch())
                display.sleep();
        }
        display.dispose();
    }


    // ==================== 5. Creators ====================

    private static void createContents(final Composite parent)
    {
        final Composite mainContainer = new Composite(parent, SWT.NULL);

        mainContainer.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

        createHeaderRow(mainContainer);

        createRow(mainContainer);
        createRow(mainContainer);
        createRow(mainContainer);
    }


    /**
     * @param parent Must have a grid layout with 5 columns!
     */
    private static void createHeaderRow(final Composite parent)
    {
        new Label(parent, SWT.NULL); // Filler label

        final Label nameLabel = new Label(parent, SWT.BORDER);

        final Label usernameLabel = new Label(parent, SWT.BORDER);
        usernameLabel.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));
        usernameLabel.setText("Username");

        final Label passwordLabel = new Label(parent, SWT.BORDER);
        passwordLabel.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));
        passwordLabel.setText("Password");
    }


    /**

        final Combo combo = new Combo(parent, SWT.NULL);
        combo.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));

        final Text usernameWidget = new Text(parent, SWT.NULL);
        usernameWidget.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));

        final Text passwordWidget = new Text(parent, SWT.NULL);
        passwordWidget.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));
    }

}

Text dashUsername=新文本（容器，SWT.NONE）；dashUsername.setLayoutData（新的GridData（SWT.FILL，SWT.start，false，false，2，1））；Text dashPassword=新文本（容器，SWT.PASSWORD）；dashPassword.setLayoutData（新网格数据（SWT.FILL，SWT.start，false，false，2，1））；我尝试过这个，发现文本与现有代码正确对齐。谢谢你的帮助。
