It's probably faster to build the HTML for the entire row and add the row to the table rather than adding each individual element one at a time. You could also extend that to building all of the HTML in a string, then adding it all at one go, which would be even faster. In an MVC environment, I'd probably return a partial view (HTML) that has the table since that would maintain separation of concerns. I would avoid building HTML on the server (in a controller), though, as that would mean that you'd have to change code whenever you wanted to change how the table was displayed. If you're using PHP or another scripting language, then filter as appropriate for your environment.

var html = '';
for (var key=0, size=data.length; key'
             + data[key][1]
             + ''
             + data[key][2]
             + '';
}

$('#dataTable').append(html);
