After same experiments I stop by following:
public static final class IssueHeadersToolbar extends HeadersToolbar {
public IssueHeadersToolbar(DataTable table, ISortStateLocator
stateLocator) {
super(table, stateLocator);
get("headers:1:header").add(new AttributeModifier("class", true,
new Model("check")));
}
}
But, this isn't supportable solution ;(
