Styling anchor

Hello,

I have a question about style this CI codes.  How to style the link ID, Content Name, etc.

I would like to take off the underline and change the font color into black.  I already try to add css to <td> and it does not change the font.  I know css but do not know how to integrate it with CI codes.  Please help.

views/contents.php

PHP Code:

<table border="0" style="width: 100%; height: 90px;">
                            <tr>
                                <td><?php echo anchor('', 'ID'); ?></td>
                                <td><?php echo anchor('', 'CONTENT NAME'); ?></td>
                                <td><?php echo anchor('', 'CREATE DATE'); ?></td>
                                <td><?php echo anchor('', 'EDIT'); ?></td>
                                <td><?php echo anchor('', 'DELETE'); ?></td>    
                            </tr>
