Using table cell value for javascript not

I have following table test data which is filtered using checkboxes. I want the <script> to use the value in each <td> and not the <td class> in order to show/hide rows based on the checkbox selections.

Is this possible by amending my current script in a simple way? it would make it a lot easier using the data I have to simple use the values rather than having to manually change the class as I add rows?

$(document).ready(function() {
  $("#type :checkbox").click(function() {
    $("td").parent().hide();
    $("#type :checkbox:checked").each(function() {
      $("." + $(this).val()).parent().show();
    });
  });
  $("#fee :checkbox").click(function() {
    $("td").parent().hide();
    $("#fee :checkbox:checked").each(function() {
      $("." + $(this).val()).parent().show();
    });
  });
});
