Do you you mean you want the controls to light up only when you hover over a specific column? It's difficult to tell by the phrasing of your question.

If so, use the column # as a condition to display the hover, e.g.

                if(this.getEventColumn() == this.getFieldNum("capital")){

                return rollOverCanvas;

            } else {

                return null;

            }
