Answer 1

Use event.stopPropagation() and event.preventDefault to disable events

$('#columnsListDropDown a').on('click', function( event ) {

    var input = $(this).find("input");
    var columnName = $.trim($(this).text());
    if (event.target.localName === "input") {
    // Case where user has clicked on the input
        if ($(input).is(':checked')) {
            $("#myTable").find("[data-column='"+columnName+"']").show()
        } else {
            $("#myTable").find("[data-column='"+columnName+"']").hide()
        }
    } else {
     event.preventDefault();
     event.stopPropagation();
    // Case where the user has clicked on the label, or in li element
        if ($(input).is(':checked')) {
            $("#myTable").find("[data-column='"+columnName+"']").hide()
            $(input).prop('checked', false);
        } else {
            $("#myTable").find("[data-column='"+columnName+"']").show()
            $(input).prop('checked', true);
        }
    }
    return false;
});
