Vertical align in bootstrap table

I am trying to display a table with 4 columns, one of which is an image. Below is the snapshot:-

I want to vertically align the text to the center position, but somehow the css doesn't seem to work. I have used the bootstrap responsive tables. I want to know why my code doesn't work and whats is the correct method to make it work.

following is the code for the table

CSS

img {
    height: 150px;
    width: 200px;
}
th, td {
    text-align: center;
    vertical-align: middle;
}

HTML

<table id="news" class="table table-striped table-responsive">
    <thead>
        <tr>
          <th>Name</th>
          <th>Email</th>
          <th>Phone</th>
          <th>Photo</th>
        </tr>
    </thead>
    <tbody>
        <?php
        $i=0;
        foreach ($result as $row) 
        { ?>
        <tr>
            <td>
                <?php echo 'Lorem Ispum'; ?>
            </td>
            <td>
                <?php echo '[email protected]'; ?>
            </td>
            <td>
                <?php echo '9999999999'; ?>
            </td>
            <td>
                <?php echo '<img src="'.  base_url('files/images/test.jpg').'">'; ?>
            </td>
        </tr>

        <?php
        }
        ?>           
    </tbody>
</table>

Based on what you have provided your CSS selector is not specific enough to override the CSS rules defined by Bootstrap.

Try this:

.table > tbody > tr > td {
     vertical-align: middle;
}

In Boostrap 4 and 5, this can be achieved with the .align-middle Vertical Alignment utility class.

<td class="align-middle">Text</td>

As of Bootstrap 4 this is now much easier using the included utilities instead of custom CSS. You simply have to add the class align-middle to the td-element:

<table>
  <tbody>
    <tr>
      <td class="align-baseline">baseline</td>
      <td class="align-top">top</td>
      <td class="align-middle">middle</td>
      <td class="align-bottom">bottom</td>
      <td class="align-text-top">text-top</td>
      <td class="align-text-bottom">text-bottom</td>
    </tr>
  </tbody>
