Display parent category ans child seperatley

Hi, at the moment I have my posts displayed in a table with title, category and date. How can I add the child category in a separate column cos at the moment it displays both under category?

Here is the code as it is now:

<td style=”padding-left:20px;”>” rel=”bookmark” title=”Permanent Link to <?php the_title_attribute(); ?>”><?php the_title(); ?></td>

<td align=”center”><?php the_category(‘, ‘) ?></td>

<td align=”center”><?php the_time(‘F jS, Y’) ?></td>

Thanks in advance 🙂
