Select a specific column in table by content

To select a specific column by content, you can use the following jquery code:

$(document).ready(function () {
        $('td').each(function () {
            var $tds = $(this).find('td');
            if ($tds.text() == "System Settings") {
                <!--alert($currText = $tds.eq(0).text());-->
                $tds.css("background-color", "#F6F6F6");
            }
