Move td to new column

Question

I have a table like that:

<table>
  <tr>
    <td>some column|1</td>
    <td id="abc|1">abc</td>
  </tr>
  <tr>
    <td>another column|1</td>
    <td id="def|1">def</td>
  </tr>
  <tr>
    <td>some column|2</td>
    <td id="abc|2">abc</td>
  </tr>
  <tr>
    <td>another column|2</td>
    <td id="def|2">def</td>
  </tr>
</table>

How can I move the tds with the suffix |2 to the right, so adding a 3rd column? Also, the remaining "empty" td "some column|2" and "another column|2" should be removed completely.

The final result should look as follows:

This is the desired code:

<table>
  <tr>
    <td>some column|1</td>
    <td id="abc|1">abc</td>
    <td id="abc|2">abc</td>
  </tr>
  <tr>
    <td>another column|1</td>
    <td id="def|1">def</td>
    <td id="def|2">def</td>
  </tr>
</table>

This is my approach, which doesn't work:

$("table td:nth-child(2)[id$=2]").after("table td:nth-child(2)");

FIDDLE.

Answer 1

Use this code

var firstTd = $("table").find("tr:nth-child(3) > td:nth-child(2)");
var secondTd = $("table").find("tr:nth-child(4) > td:nth-child(2)");

$("table").find("tr:nth-child(3), tr:nth-child(4)").remove();
$("table").find("tr:nth-child(1)").append(firstTd);
$("table").find("tr:nth-child(2)").append(secondTd);

table, tr, td {
    border: 1px solid black;
}

  </tr>
  <tr>
    <td>another column|1</td>
    <td id="def|1">def</td>
  </tr>
  <tr>
    <td>some column|2</td>
    <td id="abc|2">abc</td>
  </tr>
  <tr>
    <td>another column|2</td>
    <td id="def|2">def</td>
  </tr>
</table>

Answer 2

One way to achieve what you want:

// Values for new column to be added
var newVals = $("table td:nth-child(2)[id$=2]");

$("table td:nth-child(2)[id$=1]").each(function (ind) {
  if (ind < newVals.length) {
    // Get New Element to add
    var newElement = newVals[ind];
    // Remove original row for this element
    $(newElement).parent().remove();
    // Append to new column
    $(this).after($(newElement));                
  }
});

<table>
  <tr>
    <td>some column|1</td>
    <td id="abc|1">abc</td>
  </tr>
  <tr>
    <td>another column|1</td>
    <td id="def|1">def</td>
  </tr>
  <tr>
    <td>ome column|2</td>
    <td id="abc|2">abc</td>
  </tr>
  <tr>
    <td>another column|2</td>
    <td id="def|2">def</td>
  </tr>
</table>
