jQuery-更改表格单元格的位置

Question

how can I change via jquery the cells position from 1 2 to 2 1 ?

<table id='mytable'>
   <tr>
       <td>1</td>
       <td>2</td>
   </tr>
</table>

Answer 1

$('#mytable tr td:eq(0)').appendTo('#mytable tr');

JSFIDDLE 。

Answer 2

If you want to change all the second td to first position in your table, then you can use:

$.each($('#mytable tr td:eq(1)'), function() {
     $(this).insertBefore($(this).prev());
})

Actually, above code will not work if your table have more than one <tr> element, if that is the case then you need to use .find() :

$('#mytable tr').find('td:eq(1)').each(function() {
    $(this).insertBefore($(this).prev());
});
