Fixed version (ground truth):
@Override protected Control createDialogArea(Composite parent){
  parent.getShell().setText(this.title);
  Composite composite=(Composite)super.createDialogArea(parent);
  composite.setLayout(new GridLayout(2,false));
  Label label=new Label(composite,SWT.NONE);
  label.setText("String_Node_Str");
  label.setLayoutData(new GridData(SWT.FILL,SWT.CENTER,false,true,1,1));
  text=new Text(composite,SWT.BORDER);
  text.setLayoutData(new GridData(SWT.FILL,SWT.CENTER,false,true,1,1));
  columns=new ComplexTableViewerColumn[]{new ComplexTableViewerColumn("String_Node_Str",false,"String_Node_Str","String_Node_Str","String_Node_Str",ComplexTableViewerColumn.COMBO_STYLE,IConstants.SCHEMATRON_TYPES,0),new ComplexTableViewerColumn("String_Node_Str",false,"String_Node_Str","String_Node_Str","String_Node_Str",ComplexTableViewerColumn.XPATH_STYLE,new String[]{},0),new ComplexTableViewerColumn("String_Node_Str",false,"String_Node_Str","String_Node_Str","String_Node_Str",ComplexTableViewerColumn.VALIDATIONRULE_STYLE,new String[]{},0),new ComplexTableViewerColumn("String_Node_Str",false,"String_Node_Str","String_Node_Str","String_Node_Str",ComplexTableViewerColumn.MULTIMESSAGE_STYLE,new String[]{},0)};
