Iterate with JQuery to a table except the first column

I want to call a function for every cell in a table except the first column. Until now, I have the following code:

<script type="text/javascript">

  $("#resultstable tr").each(function () {

    $('td', this).each(function () {
         ....do my staff...
     })

})
</script>

This apply the function to every cell in my table. If I change the code to this, I thought that it will work, but it doesn't.

<script type="text/javascript">

  $("#resultstable tr").each(function () {

    $('td :not(:first-child)', this).each(function () {
         ....do my staff...
     })

})
</script>

Just slice the elements:

$("<selector>").slice(1).each(function () {...});

.slice( start [, end ] )

Description: Reduce the set of matched elements to a subset specified by a range of indices.

Another working solution would be to build a spaghetti selector using :not and :first:

$("tr").each(function () {
   $("td:not(:first)", this).each(function () {
       // do something
   });
});

Example

var colors = ["#f1c40f", "#2ecc71"];
$("table tr").each(function() {
  $("td", this).slice(1).each(function(i) {
    $(this).css("background", colors[i])
  });
});

setTimeout(function() {
  $("table tr").each(function() {
    $("td:not(:first)", this).each(function(i) {
      $(this).css("background", colors[colors.length - i - 1])
    });
  });
}, 1000);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table border="1">
  <thead>
    <tr>
      <td>Name</td>
      <td>Age</td>
      <td>Location</td>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Alice</td>
      <td>19</td>
      <td>Europe</td>
    </tr>
    <tr>
      <td>Bob</td>
      <td>20</td>
      <td>Europe</td>
    </tr>
    <tr>
      <td>Carol</td>
      <td>15</td>
      <td>Australia</td>
    </tr>
  </tbody>
</table>
