How to disable sortable headers in Admin theme tables I'm outputting some data from a custom module as follows

theme('table', array('rows' =&gt; $rows, 'header' =&gt; $headers ));


to a custom /admin page that will be viewed using the Administrative theme.

Problem is that the headers are generated as (a) clickable and (b) the selected columns have up/down sort arrows. But when you click on the arrows, no sorting happens. 

How can I either remove this styling from the header, or implement a sort for the table?
Found the answer by reading this fine article

https://knackforge.com/blog/karalmax/drupal-7-creating-drupal-style-tables-paging-sorting-and-filter

"If you do not want a particular column to be sortable, do not specify the 'field' parameter for its header."

My headers array is now simply

   $headers = array(
      array('data' =&gt; 'UID'),
      array('data' =&gt; 'Username'),
      array('data' =&gt; 'Given Name'),
      array('data' =&gt; 'Family Name'),
      array('data' =&gt; 'Email Address')
    );


with no 'field' value specified, and the clickable headers have disappeared.
