How can I create tables like the ones at the demo?

There is nothing fancy at the tables that you see at the portfolio items at the demo. These are just good old html tables, and here is the code to replicate them:

<table cellspacing="0" cellpadding="0">
<tbody>
<tr>
<th>Specifications</th>
<th>Values</th>
</tr>
<tr>
<td>Aperture</td>
<td>ƒ/9.0</td>
</tr>
<tr class="even">
<td>Focal Length</td>
<td>24.0 mm</td>
</tr>
<tr>
<td>Exposure time</td>
<td>1/250</td>
</tr>
<tr>
<td>ISO</td>
<td>250</td>
</tr>
</tbody>
</table><br>

We wanted to reduce the amount shortcodes and extra options for Higgs, so we thought that relying just to html was the best solution. If you want to dive into html tables, you may find this article handy.

Feel like using a plugin for tables? You may find several plugins like this one at the WordPress plugin repository.
