[news.eclipse.platform.swt] Unable to dispose TableColumn

[neerajkrishnag@xxxxxxxxx (Neeraj)]

I am not able to delete all the columns in the table? The following code 
will help you, i think. 

System.out.println("before dispose" + table.getColumnCount());
			for(int i = 0; i < table.getColumnCount(); i++)
			{
				table.getColumn(i).dispose();
			}
			System.out.println("after dispose " + table.getColumnCount());

The result i got was:
before dispose : 8 
after dispose : 4

Initially there were 8 columns
Please suggest a way to delete all the columns.
