I have used this javascript function:

```
$(document).ready(function(){
    $("td").each(function() {
       if (parseInt($(this).text()) > 0) {
            $(this).css("text-align", "right");
        }
    });
});

```

By this all the numbers are right aligned. But I want that the string entered should be left aligned. I think that by using NaN it is possible but I don't know how to use it. Can some one tell me the way to use NaN or some other function?
