uitableview not shown at all

I create a UITableView programmatically and add it to a UIView:

edit1

- (void)viewDidLoad
{
[super viewDidLoad];

 previewTableView =  [[UITableView 
       alloc]initWithFrame:CGRectMake(self.previewView.frame.origin.x, 
                                      self.previewView.frame.origin.y, 
                                      self.previewView.frame.size.width, 
                                      self.previewView.frame.size.height
 )];
previewTableView.delegate   = self;
previewTableView.dataSource = self;
previewTableView.tag        = 1;

[self.previewView addSubview:previewTableView];
}

The previewView is created with XIB.

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:
    (NSIndexPath *)indexPath
 {
  NSLog(@"Height for row %d",tableView.tag);
  if (tableView.tag == 1)
  {
    CGFloat height=((UIImage*)[images objectAtIndex:indexPath.row]).size.height;
    NSLog(@"section: %i, image height: %f",indexPath.section,height);
    return height;
  }
 return 80;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
     if (tableView.tag == 1)
       return [images count];

    return 10;
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

    {
    NSLog(@"tag = %d",tableView.tag);
 if (tableView.tag == 1)
 {
    NSLog(@"indexpath images %d %d",indexPath.row,[images count]);
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
    if(cell == nil)
   {
       cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];

   }
   if ([images count] > [indexPath row])
       return cell;


   [cell.contentView addSubview:[images objectAtIndex:[indexPath row]]];
   [cell.contentView sizeToFit];
   return  cell;

}

The table is not shown (no scrolling, no rows...blank view). And in fact, the NSLog is not getting called. (images contain 2 items). Any syggestion?

Instead of

previewTableView = [[UITableView alloc] init];

use:

previewTableView = [[UITableView alloc] initWithFrame:CGRectMake(101, 45, 100, 416)];

Your numberOfRows must return more than 0.

you have to specify the frame for the tableview while creating programatically. ex:

tab2 = [[UITableView alloc]initWithFrame:CGRectMake(0, 540, 768, 600)];

if you want table to occupy full screen.

tab = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain];
