live demo jsfiddle

edit1:

before column adding :before adding column after adding column table should :after adding column

please see jsfiddle demo

try

$(document).ready(function () {     var id = 0;     // add button functionality     $("table.dynatable button.add").click(function () {         id++;         var master = $(this).closest("table.dynatable");         // new row based on prototype row         var prot = master.find("tr.prototype").clone();         prot.attr("class", "")         prot.find(".id").attr("value", id);         master.find("tbody").append(prot);     });      // remove button functionality     $("table.dynatable button.remove").live("click", function () {         $(this).parents("tr").remove();      });      $("table.dynatable button.addcolumn").click(function () {         var $this = $(this), $table = $this.closest('table')         var columnname = window.prompt("enter column name", "");          $('<th>' + columnname +'</th>').insertbefore($table.find('tr').first().find('th:last'))          var idx = $(this).closest('td').index() + 1;         $('<td><input type="text" name="col' + idx + '[]" value="" /</td>').insertbefore($table.find('tr:gt(0)').find('td:last'))     }); });
