add tooltip to table column header

Hi I’ve created this shortcode:

[su_tooltip style="light" position="west" shadow="no" rounded="yes" size="default" title="" content="About actions" behavior="hover" close="no" class=""]i[/su_tooltip]

I would like to insert it after the word <th> Actions </th> in the column header.

<tr>
         <th>System/State</th>
         <th>Complaint / Use</th>
         <th>Actions</th>
         <th>Preparation and Administration</th>
         <th>Parts Used</th>   
          <th>Source</th>   
     </tr> 

How would I do that?
Thanks for your help
