{
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 40)];
    
    [headerView setBackgroundColor:[UIColor grayColor]];
    
    UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 113, headerView.frame.size.height)];
    nameLabel.font = [UIFont systemFontOfSize:14];
    nameLabel.numberOfLines = 0;
    nameLabel.textAlignment = NSTextAlignmentCenter;
    nameLabel.text = @"Name";
    [headerView addSubview:nameLabel];
    
    nameLabel = [[UILabel alloc] init];
    nameLabel.numberOfLines = 0;
    nameLabel.font = [UIFont systemFontOfSize:14];
    nameLabel.frame = CGRectMake(175, 0, 50, headerView.frame.size.height);
    nameLabel.text = @"Risk Level";
