A grid could be both <div> based or using a <table>.

You can give every element class a unique ID and trigger on that.

On the top of my head, a bit like:

<div class="button" id="b1">A</div>

<div class="button" id="b2">B</div>

<div class="button" id="b3">C</div>

And in your JQuery code you'd do a

$('.button').click(function(){
 $.post("auth.php", { which: $(this).attr("id") });
});

Whereby your server script (auth.php) could trip which button is pressed, and hence do authentication that way.
