title: Selenium: can not locate link in table
body: <p>I am writing Selenium script. For a html page include a table, I can not use "css=table tr:nth-child(2) td:nth-child(3) a" to locate the link in the table. Selenium IDE give me the "[error] locator not found".</p>
  
  <p>But use "css=table tr:nth-child(2)",  it can locate to the row.
  So am I mistake for the css locator, I think adding the "td:nth-child(3) a" should work for the link in td , why not?</p>
  
  <p>Edit: I am using firefox 3.0.15</p>
