Why doesn't vertical-align: bottom work?

Question

css

/*адрес домена был удален*/
here is the element

<td class="col" valign="bottom" style="width:100%;vertical-align:bottom;">
          <br>
          <a class="footerlink" href="http://course.zaobrazovanie.ru" target="_blank">http://course.zaobrazovanie.ru</a><br>
          <a class="footerlink" href="http://vk.com/zaobrazovanie" target="_blank">http://vk.com/zaobrazovanie</a>
</td>

Sorry! inserted the wrong code above!
here is the element:

<table width="264" height="100%" border="0" cellpadding="0" cellspacing="0" align="right" class="force-row padding-for-desctops">
      <tbody><tr>
        <td class="col" valign="bottom" style="width:100%;vertical-align:bottom;/* height: auto; */">
          <br>
          <a class="footerlink" href="http://course.zaobrazovanie.ru" target="_blank">http://course.zaobrazovanie.ru</a><br>
          <a class="footerlink" href="http://vk.com/zaobrazovanie" target="_blank">http://vk.com/zaobrazovanie</a>
        </td>
      </tr>
    </tbody></table>

I need to press it to the bottom edge of the parent...
I've been braking for 30 minutes already...

Answer 1

Yes, put you there at the beginning of another br
And yes, Denis Ineshin is right

Answer 2

Because both the left and right columns must be in the same table. Then there will be something to push off from to align with the bottom.

Answer 3

<td class="col" valign="bottom" style="width:100%; height: 64px; vertical-align:bottom;">
          <a class="footerlink" href="http://course.zaobrazovanie.ru" target="_blank">http://course.zaobrazovanie.ru</a><br>
          <a class="footerlink" href="http://vk.com/zaobrazovanie" target="_blank">http://vk.com/zaobrazovanie</a>
</td>

So it is pressed to the bottom, it's just that the container does not have the same height as the neighboring column, because they are not in the general table ..
Here, I set the same height as the neighboring container, everything fell into place as it should.
