单独

NSString *cellIdentifierResult = [NSString stringWithFormat:@"Resultcell%ld%ld", (long)[indexPath section], (long)[indexPath row]];//以indexPath来唯一确定cell
ResultClientTableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifierResult];
if(nil == cell){
    cell = [[ResultClientTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifierResult];
}
