title: reducing space between cells in UITableView - why won't this code do this?
body: <p>any ideas why I can't reduce/remove the space between cells in a Grouped UITableView (one cell per section).  I'm including the following in the controller:</p>
  
  <pre><code>- (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
      return 0.0;
  }
  
  - (CGFloat) tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
      return 0.0;
  }
  </code></pre>
  
  <p>I'm still getting spaces between cells even with this code.  Put a border around the cells and the space isn't from the cells themselves.  </p>
