theScrollView.delegate = self;
theScrollView.bounces = YES;
theScrollView.showsVerticalScrollIndicator = YES;
theScrollView.showsHorizontalScrollIndicator = YES;
[self.view addSubview:theScrollView];

 UITableView *  table = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) style:UITableViewStylePlain];
table.contentSize=CGSizeMake(320,200);
[table setDataSource:self];
[table setDataSource:self];
[table setDelegate:self];
[table setTranslatesAutoresizingMaskIntoConstraints: YES];
table.tag = 100;

Answer 1

According to your code, you setting equal frame for both table views:

CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)

So by adding them to scroll view, you just placing them on top of each other.

Try to change the frame for second table view:

CGRectMake(320, 0, self.view.frame.size.width, self.view.frame.size.height)
