What is the meaning of indexPath?
<p>I'm new to iPhone development.
I try to operate the tableview.
So I saw some sample codes and books.
But I don't understand what is the meaning of <code>indexPath</code>.</p>

<p>Here is a line of code.</p>

<pre><code>- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath ;
</code></pre>

<p>Please explain for me he <code>indexPath</code> parameter.</p>
