Does not work at all.

Hi Natanleon,
Did you follow those instructions given in the settings? If NO then you can never successfully create sortable HTML tables.

The instructions are very clear & understandable, Just create table with THEAD & TBODY tags, use tablesorter class in table tag. That’s it! Here is a typical example how you can create HTML table using this plugin.

<table id="myTable" class="tablesorter">
  <thead>
    <tr>
      <th>Last Name</th>
      <th>First Name</th>
      <th>Marks</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Khan</td>
      <td>Farhan</td>
      <td>45</td>
    </tr>
    <tr>
      <td>Iqbal</td>
      <td>Kamran</td>
      <td>98</td>
    </tr>
    <tr>
      <td>Rana</td>
      <td>Usman</td>
      <td>79</td>
    </tr>
</tbody>
</table>

Can you see, No Button, No Links & no typical settings are required to create a sortabel table. You can see a working example HERE
