Bug 97733

3.1RC1

- run the snippet below (demonstrates the setHeaderVisible case)
- click on the shell and Table.setRedraw(false) is invoked
- click on the shell again and Table.setHeaderVisible(false) is invoked.  This 
hides the header and copies item cheese to where it was.  It seems like this
should do nothing because of the previous setRedraw(false)
- click on the shell again and Table.setRedraw(true) is invoked: now things seem
right again
- to see the Table.setColumnOrder case just uncomment the line in the MouseDown
listener and comment out the setHeaderVisible line above it

public class Main {
	static int counter = 0;
public static void main(String[] args) {
	final Display display = new Display();
	final Shell shell = new Shell(display);
	shell.setBounds(10, 10, 300, 300);
	final Table table = new Table(shell, SWT.NONE);
	table.setHeaderVisible(true);
	table.setBounds(10, 10, 200, 200);
	TableColumn column = new TableColumn(table, SWT.NONE);
	column.setText("0");
	column.setWidth(75);
	column = new TableColumn(table,SWT.CENTER);
	column.setText("1");
	column.setWidth(120);
	new TableItem(table, SWT.NONE).setText(new String[] {"abc","def"});
	shell.addListener(SWT.MouseDown, new Listener() {
		public void handleEvent(Event event) {

				//table.setColumnOrder(new int[] {1,0});
				counter++;
				return;
			}
			if (counter == 2) {
				System.out.println("setRedraw(true), item reappears");
				table.setRedraw(true);
