Answer 1

You can use JQuery and call the following command:

$("[name=List1]").show();

or

$("#reservationlist").show();

UPDATE

If you use javascript you can do:

document.getElementById("reservationlist").style.display="block";

UPDATE2 To hide table you can use

$("#reservationlist").hide();

or

document.getElementById("reservationlist").style.display="none";
