Enabling single column selection in org.eclipse.swt.widgets.Table - eclipse-rcp

Question

I have used the org.eclipse.swt.widgets.Table
Code implementation will look like this
Table table = new Table(shell, SWT.SINGLE | SWT.BORDER | SWT.FULL_SELECTION);
But i need behavior like if mouse clicked on 'Sec_1' i want only 'Sec_1' to be selected not entire row and if mouse clicked on 'First_1' i don't want it to be Highlighted(FirstColumn no selection).
Can any one help me ?
