title: Style for last td of last tr of certain class in table
body: <p>I need to apply style to last cell of last row of class "fose_table_row".
  Table is next </p>
  
  <pre><code>&lt;table class="fose_table"&gt;
      &lt;tr&gt;
          &lt;th&gt;1&lt;/th&gt;
          &lt;th&gt;2&lt;/th&gt;
      &lt;/tr&gt;
      &lt;tr class="fose_table_row"&gt;
          &lt;td&gt;3&lt;/td&gt;
          &lt;td&gt;4&lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr class="fose_edit_row"&gt;
          &lt;td colspan="4"&gt;56&lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr class="fose_table_row"&gt;
          &lt;td&gt;7&lt;/td&gt;
          &lt;td&gt;8&lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr class="fose_edit_row"&gt;
          &lt;td colspan="4"&gt;90&lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Rows of class <code>fose_edit_row</code> are not visible rows so I need last of <code>fose_table_row</code> to be styled. 
  I tried <code>.fose_table .fose_table_row:last-child td:last-child</code> and <code>.fose_table tr.fose_table_row:last-child td:last-child</code> but that doesn't seem to work. Last or of class <code>fose_edit_row</code> gets styled.  What is right way to do this? And is it even possible?</p>
