FireFox 4 no longer supports scrollable TBody - wo

Well as mentioned in the Firefox 4 changelog, there will be no longer support for scrollable <tbody>'s.

There are a bunch of workarounds - javascript or 2 seperate tables - but none of them solves all problems. Javascript is obviously slower (with 600 rows you can forget to try to scroll a table), and 2 tables are gonna be problematic with cell-width.

Do you know if there is some cool way to do this? We are using jsf / facelets and now have to redo the tags, starting with a good idea would be awesome :-)

Try the first method of this page, pure CSS with a single table (2 divs around the table, and the thead is positionned absolute) : tablescroll Seems to work on FF4/IE9/IE8 in addition to IE7/FF3.6.

PrimeFaces and RichFaces have scrollable datatable components which fetches new rows by ajax.

(both JSF component libraries uses jQuery under the covers anyway)

I worked on a frameworkless prototype I want to share with you. It's working in Firefox 4+, IE7-8 (haven't checked 6 or 9) Safari and Chrome.

The biggest unsolved problem is what to do when the static headers run out of room to shrink before the data columns do.

For the actual project I was working on frankly I backed out of the scrolling tbody and went with pagination. but I was dealing with 25+ columns with sorting and potentially 1000s of rows.

Anyway this is where I got to before I abandoned it. Please post your additions if you improve it: Hope this helps.

Link to an example

I know you're trying to avoid js/separate table implementations, but it was the only one I could find that worked across multiple browsers. Try http://www.tablefixedheader.com/. It's a jquery solution and worked, in my limited testing, across IE6 / IE8 / FF3. (Haven't tested FF4).

Thanks to digitaldigs from MozillaZine, I was able to make it work with few modifications. The fix works great for FF4, FF7 and FF11.

I hope this helps! :)

Issues I have fixed- 1. scrollWidth did not work for me so had to go for offsetWidth

  1. Scroll bar width 16 pixel also was not helping so removed it. Instead made my tbody style as-

    .scrollContent { overflow-x:hidden; overflow-y:scroll; /* I did this only for Mozilla. IE will show 2 scroll bars if applied*/ display:block; }

  2. With change #2, I had to pad the last cell of the header to accomodate scroll bar.

    /* I did this only for Mozilla. Not for IE*/

    .fixedHeader tr th:last-child { padding-right: 20px; }

  3. My fixed header table has colspan used a lot hence was not able to set width, so I first look for a correct row with correct number of cells and then I process.

My code looks like below:

function makeMeFixedHeader(){ 
    var tbodys = document.getElementsByName("scrollTableBody");
    if (tbodys){
        for(var i=0;i<tbodys.length;i++){
            // We can put logic here to check if the current height 
            // of tbody has crossed the specified limit or not 
            do_tbodyscroll(tbodys[i]);
        }
    }
}


function do_tbodyscroll(_tbody){
    // get the table node 
    var table = _tbody.parentNode;

    // Get the Last row in Thead ... 
    // COLGROUPS USING COLSPAN NOT YET SUPPORTED
    var thead = table.getElementsByTagName("THEAD")[0];
    var _rows = thead.getElementsByTagName("TR");

Why not use a scrollable div? Maybe one of these two options:

<table>
 <row>
  <cell>
   <div of headers>
   <div of content (scrollable)>
  </cell>
 </row>
</table>

or simpler:

<div of headers>
<div (scrollable)>
 <table of content, no headers>
</div>

Not pretty I know but hey I'm no Michaelangelo :)
