I am assuming I am doing something wrong.
Thanks.

<div class="ws-css-table"  >
  <div class="ws-css-table-tr">
        <div class="ws-css-table-td"></div>
        <div class="ws-css-table-td"></div>

$('#css-icol').click(function(){
    $(".ws-css-table-td:last").clone().appendTo('.ws-css-table-tr');

  var tblArr = $('.ws-css-table > .ws-css-table-tr').map(function ()
   {
    return $(this).children().map(function ()
    {
        return $(this);
    });

  1. You have an error in this line: 

    $(".ws-css-table-td:last").clone().appendTo('.ws-css-table-tr');

    You select the last cell in the table and clone it to every row. When you want to copy the column, you have to select last cells in all rows, then you have to iterate over the cloned cells. Finally, the method after is more elegant here… 

    $(".ws-css-table-td:last-child")
  .each(function(){
    var $this=$(this)
    $this.after($this.clone())
  })

    To create an empty column use: 

    $(".ws-css-table-td:last-child")
  .after("<div class='ws-css-table-td'/>")
