Array
(
    [0] => Array
        (
            [user_id] => 1
            [user_name] => Test 1
            [user_mail] => test3@test.com;test3@admin.com;admin3@test.com
        )

    [1] => Array
        (
            [user_id] => 2
            [user_name] => Test 2
            [user_mail] => test3@test.com;test3@admin.com;admin3@test.com
        )

    [2] => Array
        (
            [user_id] => 1
            [user_name] => Test 2
            [user_mail] => test3@test.com;test3@admin.com;admin3@test.com
        )

)

将此数组传递给您的视图。

$data['user_det'] = $user_data;
$this->load->view('your_view',$data);

视图代码：

<table border="1">
    <thead>
        <tr>
            <th>User id</th>
            <th>User Name</th>
            <th>Emails</th>
        </tr>
    </thead>
    <tbody>
        <?php foreach($user_det as $val){
        $email = explode(';',$val['user_mail']);
        ?>
        <tr>
            <td><?php echo $val['user_id'] ?></td>
            <td><?php echo $val['user_name'] ?></td>

            <td>    
            <?php  foreach($email as $val2){ ?>     
                <a href="mailto:<?php echo $val2; ?>"><?php echo $val2; ?></a><br>
            <?php } ?>
            </td>
        </tr>
        <?php } ?>
    </tbody>
</table>
