Outputting HTML is easy. HTML is text.

Code:
#!/bin/sh

echo "<html><body>This is HTML</body></html>"

PHP is a language specifically designed to present results in HTML. It has the power of a full scripting language, and you can intermix raw HTML and PHP with ease.
Code:
<html>
  <body>
<?php   $dspec=array(   1       =>      array("pipe", "w")      );
        $proc = proc_open("ps ux", $dspec, $pipes );

        ($proc) || die("Couldn't run 'ps ux'");         ?>
    <table width='100%'>
      <tr>
<?php   $line=fgets($pipes[1]);
        $titles=preg_split("/[\s]+/",$line);

        for($n=0; $n<sizeof($titles); $n++)
        {                                               ?>
        <th><?=$titles[$n]?></th>
<?php   }                                               ?>
      </tr>
<?php   while($line=fgets($pipes[1]))
        {
                $titles=preg_split("/[\s]+/",$line);
                                                        ?>
      <tr>
<?php           for($n=0; $n<sizeof($titles); $n++)
                {                                               ?>
        <td><?=$titles[$n]?></td>
<?php           }                                               ?>
     </tr>
<?php   }       ?>
    </table>
  </body>
</html>
<?php   proc_close($proc);      ?>

This will produce an HTML table like so:

Code:
<html>
  <body>

    <table width='100%'>
      <tr>
        <th>USER</th>
        <th>PID</th>
        <th>%CPU</th>

        <th>%MEM</th>
        <th>VSZ</th>
        <th>RSS</th>
        <th>TTY</th>
        <th>STAT</th>
        <th>START</th>

        <th>TIME</th>
        <th>COMMAND</th>
        <th></th>
      </tr>

      <tr>
        <td>apache</td>
        <td>13019</td>

        <td>0.0</td>
        <td>3.6</td>
        <td>16120</td>
        <td>8096</td>
        <td>?</td>
        <td>S</td>

        <td>Jul30</td>
        <td>0:00</td>
        <td>/usr/sbin/apache2</td>
        <td>-D</td>
        <td>USERDIR</td>
        <td>-D</td>

        <td>DEFAULT_VHOST</td>
        <td>-D</td>
        <td>SSL</td>
        <td>-D</td>
        <td>PHP5</td>
        <td>-d</td>

        <td>/usr/lib/apache2</td>
        <td>-f</td>
        <td>/etc/apache2/httpd.conf</td>
        <td>-k</td>
        <td>start</td>
        <td></td>

      </tr>

      <snip for brevity>

    </table>
  </body>
</html>

...obviously not perfect, since PS doesn't use tabs for seperators(for reasons I can't imagine), but hopefully shows the idea.

PHP can be run on a web server -- the UNIX forums run on it -- in which case the code is executed and the results presented to you. You can also run it from the command prompt directly via 'php file.php'.
