在表的每一行上显示CKEditor

I want CKEditor to be shown on each row ot a table, but it appears only on the first row. On the other rows only textarea is shown, without CKEditor. I use Codeigniter. That's my view:

<?php
foreach ($query as $row) {
    echo "<table border='1'>";
    echo "<tr>";
    ?>
    <td class='col-md-2'>
    <textarea  name="content" id="content"></textarea> 
    <?php 
    echo display_ckeditor($ckeditor);
    ?>
    </textarea></td></tr>
    <?php
}
?>

My controller is:

<?php
//some code

        $data['ckeditor'] = array(
 
            
            'id'    =>   'content',
            'path'  =>   'js/ckeditor',
 
            
            'config' => array(
                'toolbar'   =>   "Full",     
                'width'     =>   "550px",    
                'height'    =>   '100px',    
 
            ),
                
                )               
            )
        );
        

How should be done to be shown on each row?

Try to give id dynamically rather than 'content'.
