使用Jquery突出显示表中特定的数据列

Question

我想使用Jquery突出显示正常html表中特定列中的特定数据字段。可以为此场景提供一段代码。我已经实现的是突出显示Solr的记录，但不知道如何将其应用于连续的确切列。

var newresult = {"_header": { 
     "nvPairs": [ 
        "status", 
        0,

//var result = res[0].replace(new RegExp(word, 'g'), '<em>harsha</em>'); 






    $("body").append('<div>' + result + '</div>'); 



});

    $secondCell.css('backgroundColor','yellow'); 
} 
if($thirdCell.text() != $fourthCell.text()){ 
    $thirdCell.css('backgroundColor','orange'); 
    $fourthCell.css('backgroundColor','orange');
