How to make a table, which is wider than screen size, scrollable and keep header row fixed?

I've a table with 2 columns and each column is 800px wide. I want to show this table in 800x50 window. So there should be horizontal and vertical scrollbar to view complete 开发者_运维知识库table.

While I've found few related solutions (this and this) on SO, they only work if table width is smaller than screen size. In my case screen size is 1200px and total table width is 1600px.

How could I do this? i want to achieve something like this.

EDIT Oops, I forgot to add one more requirement. Sorry. I want the header of the table to remain fixed while user scrolls table.

EDIT2

I've tried below mentioned solutions to wrap in a div, but in this case vertical scrollbar doesn't show up. Please see this table with wrapper div. It seems this problem only occurs if table width is bigger than screen size. I'm testing on FF3.6.

EDIT3

current table code. This has no vertical scroller even though I can scroll vertically.

<div style="overflow:scroll; width:800px;height:50px" >
<table style="width:1600px" border="1">
  <thead>
    <tr>
        <th style="width:800px">id_1</th>
        <th style="width:800px">id_1</th>
    </tr>
  </thead>
  <tbody style="">
    <tr><td>1200</td><td>1200</td></tr>
    <tr><td>1200</td><td>1200</td></tr>
    <tr><td>1200</td><td>1200</td></tr>
    <tr><td>1200</td><td>1200</td></tr>
    <tr><td>1200</td><td>1200</td></tr>
    <tr><td>1200</td><td>1200</td></tr>
  </tbody>
</table>
</div>

You could wrap the table in a div that has a fixed-size (800x50) and set overflow:scroll.

Put your table in a div with width < 800, and set overflow: scroll.

I don't know if it would work, but have you tried setting max-width: 100% for the page?

Just add overflow:scroll to the css of your table element. Btw. your example doesn't show any scrolling.

If you want the header to remain fixed you just do some css

#header {
  position:fixed;
  left:0;
  top:0;
}
