I think that doing away with neither UITableView’s userInteractionEnabled set to YES, and implementing your own touchesMoved:withEvent: method (maybe also try UIGestureRecognizers) would prove fruitful.

I am guessing that these UITableViews are not used to show plain tabular data but images or other content, and have a different interaction paradigm (e.g., when the two fingers slide separately the two table views scroll in separate velocity & direction). If that is the case you might ultimately want to use custom controls.

But if you just want a 2-column UITableView then as Jonathan said, simply use a two-column cell.

If you want to implement 2 separated and round-rected columns then it might make some sense.

In any other case just use one UITableView and separate each cell visually (the left half will display the data for the first column and the right - for the second).

If you still want to have 2 separate table views and have them both scrolled simultaneously then get rid of the containing scroll view and implement the UIScrollViewDelegate as was already suggested.
Something like this:

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    self.leftTableView.contentOffset = scrollView.contentOffset;
    self.rightTableView.contentOffset = scrollView.contentOffset;
}

I think that this code should do the magic...

Don't forget to set the view controller to be the delegate of both table views.

Can you post a picture, or clearer description of what you want?

If your next question is "how do I make the scroll views stay at the same offset?" -- i.e. you want them to sync vertically -- than I would advise that you abandon the idea of using two UITableViews.

Instead, define a two-column UITableViewCell, which can easily be done with Interface Builder, and use that to give the appearance of two columns.

I don't really get it but a table View on top of a scroll View will create problems. Because, when users scroll, both of the views will try to get the interaction of the user, and they can take turn to get that interaction randomly.
