I have a table that has a column that is either clicked or not. if clicked == 1, I want to show a font-awesome checkmark in the table cell, otherwise its blank. That all works fine. What is not working is the jquery tablesorter. When I click the column head, nothing is sorted. I have added the parser-input-select.min.js file with no luck.

if($clicked == 1){
    $billable = '<i class="fa-solid fa-check"></i>';
}else{
    $billable = '';
}
