I use jqGrid with many columns containing boolean information, which are displayed as checkboxes inside the table (see http://www.ok-soft-gmbh.com/VerticalHeaders/TestFixedO

Here's a working jsfiddle that does it. It should work in IE 6, I only used jquery and raphael js. I made static sizes for the raphael drawing area and the text, but you can certainly do a little math to figure out dynamic sizes:

http://jsfiddle.net/UYj58/9/

Code looks like this if you include jquery and raphael:

$(document).ready(function(){
    var font = {font: '12px Helvetica, Arial'};
    var fill = {fill: "hsb(120deg, .5, 1)"}
    $('tr th div').each(function (index, div){
        R = Raphael($(div).attr('id'), 20, 100);
        R.text(4, 50, $(div).find('span').text())
            .attr(font)
            .attr(fill)
            .rotate(-90, true);
        $(div).find('span').hide();
    });
});

And the HTML looks like this:

<table>
    <thead>
        <tr>
            <th><div id="columnOne"><span>heading one</span></div></th>
            <th><div id="columnTwo"><span>heading two</span></div></th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>1</td>
            <td>2</td>
        </tr>
        <tr>
            <td>4</td>
            <td>5</td>
        </tr>
    </tbody>
</table>

Oh, and I used this as my example: http://raphaeljs.com/text-rotation.html

Canvas text transformations example

            <!--[if IE]><script type="text/javascript" src="../excanvas.js"></script><![endif]-->
<script type="text/javascript" src="../canvas.text.js"></script>
<script type="text/javascript" src="../faces/dejavu_sans-normal-normal.js"></script>
<script type="text/javascript" src="../faces/dejavu_sans-bold-normal.js"></script>
    </head>
    <body>
            <canvas width="500" height="300" id="test-canvas" style="font-size: 16px;"></canvas>

            <script type="text/javascript">
                function initCanvas(canvas) {
                    if (window.G_vmlCanvasManager && window.attachEvent && !window.opera) {
                        canvas = window.G_vmlCanvasManager.initElement(canvas);
                    }
                    return canvas;
                }

                window.onload = function() {
                    var canvas = initCanvas(document.getElementById("test-canvas")),
                                ctx = canvas.getContext('2d');

                    ctx.strokeStyle = "rgba(255,0,0,1)";
                    ctx.fillStyle = "rgba(0,0,0,1)";
                    ctx.lineWidth = 1;
                    ctx.font = "20pt Verdana, sans-serif";
                    ctx.strokeStyle = "#000";
                    ctx.rotate(Math.PI / 2);
                    ctx.fillText('Vertical', 0, 0);
                    ctx.restore();
                }
            </script>
    </body>
