Answer 1

$(".b1") and $(".b2") are selecting every element with that class. You need to filter based on the row the button is in using something like this:

$("button").click(function(){
    var $row = $(this).closest("tr");
    $row.find(".b1").load("content.txt");
    $row.find(".b2").load("content1.txt");
});
