Found the reason: "iframe" is the reason for this. It should be fine as long as getting rid of iframe and frame.

"search" will mess up the first row(header row).
If the table includes checkbox as a column, "table copy" used here will make "uncheck checkbox" not working, as someone mentioned in reply below.

Great script, but I'm searching a way to set height and width of the table.
Any way I've tryed, it didn't work.
Any suggestion? 
|
|
|
|
|
I've found a way: simply give "display:block" at the table and it will take the right dimensions.
Thanks anyway

I have been working on Scrollable tables from past 2 years. I have implemented fix header table using CSS and JavaScript.
Scrollable Table in IE
Scrollable in All
Please let me know if you have any suggestions for me

Hi.
This mostly works - except the first column and top row don't scroll when the table is scrolled.

Hi
I've made a version of the script that supports freezing multiple columns.
The HTML should look like this:
<pre>
<div id="outerDiv">
<div id="innerDiv">
<table>
<thead>
<tr>
<th>Table</th>
<th>Column 1</th>
<th>Column 2</th>
<th>Column 3</th>
<th>Column 4</th>
<th>Column 5</th>
<th>Column 6</th>
<th>Column 7</th>
<th>Column 8</th>
<th>Column 9</th>
<th>Column 10</th>
<th>Column 11</th>
<th>Column 12</th>
</tr>
</thead>
<tbody>
<tr>
<th>Row 1</th>
<th>Value 1</th>
<td>Value 2</td>
<td>Value 3</td>
<td>Value 4</td>
<td>Value 5</td>
<td>Value 6</td>
<td>Value 7</td>
<td>Value 8</td>
<td>Value 9</td>
<td>Value 10</td>
<td>Value 11</td>
<td>Value 12</td>
</tr>
...

Very Good Job!
Thx
|
|
|
|
|
It works very well!
Thank you very much! To you and Kenneth too.

I tried adding Kenneth's fix and it only partially works. I can scroll right to left, but not up and down. I wrapped the top row in a "thead" tag, and the rest of the rows in a "tbody" tag.

|
|
|
|
Scratch that, it works just fine. I just need to shrink the screen down to get the vertical scrollbar. Fantastic job, this is just what I was looking for.

It is not working in case of Mozzila firefox, Can anyone help,
|
|
|
|
|
Ok, I tried on IE and it's not working.
I mean. I want the table to have a fixed size (something like 500px) and the scroll to work.
But the table always show up big, the width and height on the css doesn't work when the javascript command 'CreateScrollHeader' is on (true).
What's wrong? I'm using IE7.
Tks

Thanks Karin for the above solution, it works great. However, i am facing a problem that events are not firing for the controls placed in fixed column headers. The page postback is happening but the event is not firing. The events for controls in non-fixed columns are firing. What could be the problem? Any help is appreciable...

I did tried lots of script and JQuery library, but if it's a big table with lots of rows few of this scripts make it slow, few script does not works in some browser. At last I found the best way to create the scrollable table with fixed row or column. I am using it in my huge ERP application, it is really fast and works great on Mozilla Firefox, IE, Opera and Google chrome. To see the detail please visit to

Thanks Karin for a great solution. In my scollable table I have checkboxes and when you click on them I have a function that checks the status of the checkbox, i.e. checked or not. The problem that I am experiencing is that, even when a checkbox is checked, it returns false. All my checkboxes have a unique id. I'm not sure how to solve this, I will appreciate any ideas.
Thanks, Asha.

Because the javascipt duplicates the contents of the table to the top and left, multiple instances of your form elements will be created. This might result in different results when collecting the form elements when submitted.

can anyone please suggest a solution for this issue.

Great piece of work here thanks! Does anyone have any ideas on altering this code so that you could freeze multiple left hand side columns? Haven't figured out how to do that using this solution yet.
Thanks!

First off I must say "WOW". This is some great code. But have you figured out yet how to modify this to freeze more than 1 column? It would be awesome to have the first 3-4 left columns to freeze as well. I've just spent about 3 weeks banging my head against the CSS wall trying to this and I'm just amazed at the speed. Thanks.

Here's the solution I used-
Nest a table in each of the first (fixed) cells with the columns you want.
You will need to use fixed width for these columns as the tables don't have any relation.
You'll also want to override the top / bottom border styles on these new columns so you don't get a double border.
