{
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0,tableView.frame.size.width,40)];

    [headerView setBackgroundColor:[UIColor grayColor]];

    UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(10,113,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(175,50,headerView.frame.size.height);
