Selecting index in java table swt

I have this code which prints the data from the column in the table but how can i get the value of another columns ( I have 3 columns) but it only prints the 1st column?

This is my code:

Table table = (Table) e.widget;
            if( e.detail == SWT.CHECK ) {
                System.out.println(e.item);
                if( table.indexOf( ( TableItem )e.item ) == table.getSelectionIndex() ) {
                    TableItem ti = ( TableItem )e.item;
                    ti.setChecked( !ti.getChecked() );
                }

            } else {
                TableItem ti = ( TableItem )e.item;
                ti.setChecked( !ti.getChecked() );
            }

PS: i got the code here from stackoverflow
