SWT gridlayout align - swt

Question

When put all widgets in one container, the gridlayout could align normally.
But for some reason, I need to put some widgets to a sub-container such as the composite as below. The alignment is different.
So the question is: Is there a container that has no effect on the gridlayout?
Ps: I know that can use white space as a workaround, but...
Code:
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
GridLayoutFactory.fillDefaults().numColumns(2).margins(8, 3).applyTo(shell);
new Label(shell, 0).setText("Label1");
new Text(shell, 0);
new Label(shell, 0).setText("A long Label");
new Text(shell, 0);
Composite composite = new Composite(shell, 0);
GridDataFactory.fillDefaults().span(2, 1).applyTo(composite);
GridLayoutFactory.fillDefaults().numColumns(2).applyTo(composite);
new Label(composite, 0).setText("Label22");
new Text(composite, 0);
new Label(composite, 0).setText("Label223");
new Text(composite, 0);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
Result:

There is no container that can used like this. Sticking to a single composite is by far the easiest way to aligh the labels.
It is possible to specify the widthHint of the GridData for a label to specify the width. You would have to calculate the width required using something like:
List<Control> labels = ... list of Label controls
final int width = labels.stream()
.mapToInt(label -> label.computeSize(SWT.DEFAULT, SWT.DEFAULT).x)
.max()
.getAsInt();
final var labelData = GridDataFactory.swtDefaults().hint(width, SWT.DEFAULT);
labels.forEach(labelData::applyTo);
