If I defined an empty table in my index.html:
<body>
<table width="800" border="0" class="my-table">
<tr>
</tr>
</table>
</body>
Then, I add row and columns to my-table by invoke the following Javascript code:
var myTable = $('.my-table');
var myArr=GET_FROM_SERVER //server returns an arry of object, myArr.length>50
for(var i=0; i<myArr.length)
myTable.append("<tr id="+i+">"
+" <td>"+myArr[i].name+"</td>"
+"<td>"+myArr[i].address+"</td>"
+"</tr>");
myArr is an array of object get from server, the length of this array could be more than 50.
I got all of this working successfully, my question is, how can I add scroll bar to this table so that if there are too many rows, user could use scroll bar to check the table content.

Suppose we want to add a scroll bar option in HTML, use an “overflow” option and set it as auto-enabled for adding both horizontal and vertical scroll bars. If we want to add a vertical bar option in Html, add the line “overflow-y” in the files.
The easiest way is to put inside your cell a div filling it and set its overflow style property. If you want the scrollbar to be always visible, even when the content isn't cropped, replace auto with scroll in the CSS.
I would wrap the table with a div
<body>
<div style="overflow:scroll;height:80px;width:100%;overflow:auto">
<table width="800" border="0" class="my-table">
<tr> </tr>
</table>
</div>
</body>
The quick and easy answer is CSS overflow:scroll; on the parent element.
However, if you're trying to jazz up your tables, I'd suggest going one step further, and use a JQuery plugin like Fixed Table Header.
The nice thing about this is that it means you can scroll the table body while keeping the header in place, which makes it much easier to read when you've got large amounts of data.
You might also want a script that allows your users to click in the header and sort the table by different columns. In that case, FlexiGrid might be an even better option.

From a UI standpoint, it's going to be easier to interact with a long table if it's paged, not scrolling. Scrolling can cause some behaviors that make it difficult for users with disabilities to interact. It's easy to click a next page link, not always so easy to scroll.
I attack table problems using a grid, and my grid of choice is DataTables. It gives you paging, filtering, sorting, ordering, and ajax loading of content along with the opportunity to scroll with a fixed header if you are determined to go this route. You can even setup a download to excel, pdf, printer, etc and style on the fly with just a couple of additions. All can be setup with a few simple lines of code. By far, it's the best, quickest trick I use to make complex data quickly available to my users.
