How to pass value dynamically in JavaScript

Question

I have a table which has the column name "12" Instead of that value I want to pass it dynamically and for that I have a created item "P_Itm_val" see attached image for reference.

$('td[headers = "12"]').each(function() {
    $(this).css({"background-color":"whitesmoke"});  
    $(this).css({"color":"green"});
    $(this).css({"font-weight":"bold"});
  });

Just put the value there instead of "10"

 $('td[headers = P_Itm_val]').each(function() {
     $(this).css({"background-color":"whitesmoke"});  
     $(this).css({"color":"green"});
     $(this).css({"font-weight":"bold"});
 });

If that doesn't work, try appending the value into the call

 $('td[headers = "'+P_Itm_val+'"]').each(function() {
     $(this).css({"background-color":"whitesmoke"});  
     $(this).css({"color":"green"});
     $(this).css({"font-weight":"bold"});
 });

I'm not quite sure what I did for this however, I've done something similar to this.
