I am stuck working with a horrible application that has table driven layout. It is severely limiting and I can not add unique classes or really do anything to edit the html output. Can someone show me how I could possibly manipulate the layout using jQuery.

The code looks something like this:

<table width="100%" border="0" cellpadding="3" cellspacing="0">
    <tr>
        <td>
            <TABLE CELLPADDING="3" CELLSPACING="" BORDER="0">
                <TR>
                    <TD>
                    <TABLE CELLPADDING="3" CELLSPACING="0" BORDER="0">
                        <TR>
                            <TD STYLE="padding:3px;">
                                <TABLE CELLPADDING="0" CELLSPACING="0" BORDER="0">
                                <TD NOWRAP CLASS="MainNavigation">
                                Link 1</TD>
                  开发者_StackOverflow中文版              </TABLE>
                            </TD>
                            <TD STYLE="padding:3px;">
                                <TABLE CELLPADDING="0" CELLSPACING="0" BORDER="0">
                                <TD NOWRAP CLASS="MainNavigation">
                                Link 2</TD>
                                </TABLE>
                            </TD>
                            <TD STYLE="padding:3px;">
                                <TABLE CELLPADDING="0" CELLSPACING="0" BORDER="0">
                                <TD NOWRAP CLASS="MainNavigation">
                                Link 3</TD>
                                </TABLE>
                            </TD>
                        </TR>
                    </TABLE>

                    <TABLE CELLPADDING="3" CELLSPACING="0" BORDER="0" >
                        <TR>
                            <TD STYLE="padding:3px;">
                                <TABLE CELLPADDING="0" CELLSPACING="0" BORDER="0">
                                <TD NOWRAP CLASS="MainNavigation">
                                Link 4</TD>
                                </TABLE>
                            </TD>
                            <TD STYLE="padding:3px;">
                                <TABLE CELLPADDING="0" CELLSPACING="0" BORDER="0">
                                <TD NOWRAP CLASS="MainNavigation">
                                Link 5</TD>
                                </TABLE>
                            </TD>
                        </TR>
                    </TABLE>
                    </TD>
                </TR>
            </TABLE>
        </td>
    </tr>
</table>

Ugly right?!

So from this example how could I manipulate it with scripts to move Link 3 into the second table? I started a fiddle with this here :

Lucky for us, jQuery has ways to easily deal with such ugliness. Using :contains(), .detach(), and insertBefore() you can:

var refTD = $('.MainNavigation:contains("Link 4")').parent().closest('td');
$('.MainNavigation:contains("Link 3")').parent().closest('td')
                                       .detach()
                                       .insertBefore(refTD);
