how to capture width of table cell??? width() returning "0"??

All i want is the width of a table cell...in pixels...here's one way I've tried to get it that's not working...tried several and it's making me nuts...

  1. $('#mytable').find('thead th').each(function(){
  2.       console.log( $(this).width() ); // <== returns 0 ???
  3. })
