Answer 1

Modify the function to get a selector for all the checked check boxes.

$(function(){
  var $checkboxes = $("input[id^='type-']");
  $checkboxes.change(function() {
    var selector = '';
    $checkboxes.filter(':checked').each(function(){ // checked 
        selector += '.' + this.id.replace('type-','') + ', '; 
        // builds a selector like '.A, .B, .C, ' 
    });
    selector = selector.substring(0, selector.length - 2); // remove trailing ', '
    // tr selector
    $('table tr').hide() // hide all rows
       .filter(selector).show(); // reduce set to matched and show
  }).change(); 
});
