Just drag a UINavigationController in Interface Builder to your TabBarController, then expand the Navigation Controller, point the Root View Controller to your TableViewController.

No you should not delete your UITableView, what you want is UITableViewController that can use your UITableView.

You will need the UINavigationController when you want to show another ViewController when the user taps a row on your UITableViewController.

This tutorial explains how to do what I just described, hope it helps:

Table View and NavigationController

Just add an UINavigationController and push the view onto your screen

EDIT: This is how to add the NavigationController programmatically (e.g. in you AppDeleagte)

  UIViewController  *viewController1, *viewController2;

    viewController1 = [[[UIViewController alloc] initWithNibName:@"FirstViewController_iPhone" bundle:nil] autorelease];
    UINavigationController *navigationcontroller = [[[UINavigationController alloc] initWithRootViewController:viewController1] autorelease];

    viewController2 = [[[UIViewController alloc] initWithNibName:@"SecondViewController_iPhone" bundle:nil] autorelease];

    self.tabBarController = [[[UITabBarController alloc] init] autorelease];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:navigationcontroller, viewController2, nil];

If you have a tableview in the Viewcontroller1 you can access the Navigationcontroller by using self.navigationController e.g. in the didSelectRowAtIndexPath to open a DetailView

eg.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
    [self.navigationController pushViewController:detailViewController animated:YES];
    [detailViewController release];
}
