It's all in the cellForRowAtIndexPath, here's a small example:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath    
{
    UITableViewCell * r = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];

    if (indexPath.section == 0) {
        NSArray *a = [NSArray arrayWithObjects:@"a",@"b",@"c",@"d",@"e",nil];    
        r.textLabel.text = [a objectAtIndex:indexPath.row];  

    } else {
        NSArray *b = [NSArray arrayWithObjects:@"1",@"2",@"3",@"4",@"5",nil];    
        r.textLabel.text = [b objectAtIndex:indexPath.row];  

    }

    return r;  
}

Your main problem in the code above is that you never tell which section to inser new cell, and thus they all fell into the first one. Look into the method cellForRowAtIndexPath you need to specify that the newly created cell goes to a particular section.

Go through those example programs provided by apple.
