I use jqGrid with many columns contains Boolean information, which are displayed as checkboxes inside of table (see http://www.ok-soft-gmbh.com/VerticalHeaders/TestFixedO.htm as an example). To display information more compact I use vertical column headers. It works very well and works in jqGrid in all browsers (see my discussion with Tony Tomov in jqGrid forum http://www.trirand.com/blog/?page_id=393/feature-request/headers-with-vertical-orientation/), but in IE vertical texts are blur and look not nice enough (open the link above in IE and you will see exactly what I mean). I was asked from users why the texted displayed so strange. So I think about using a JavaScript based SVG library like SVG Web ( http://code.google.com/p/svgweb/ ) or Raphaël ( http://raphaeljs.com/ ). SVG is very powerful and it is difficult to find a good example is not very easy. I need only display vertical texts (-90 grad, from bottom to up) and use if possible without working in mode of absolute position.
So one more times my question: I need have a possibility to display vertical texts (-90 grad rotation) inside of <td> element of table header. I want use a JavaScript based SVG library like SVG Web or Raphaël. The solution must support on IE6. Have somebody a good reference to example which could help me to do this? If somebody post a whole solution of the problem I would be happy.
To be exact here is my current solution: I define
.rotate
{
-webkit-transform: rotate(-90deg); /* Safari 3.1+, Chrome */
-moz-transform: rotate(-90deg); /* Firefox 3.5+ */
-o-transform: rotate(-90deg); /* Opera starting with 10.50 */
/* Internet Explorer: */
filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3); /* IE6, IE7 */
-ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(rotation=3)" /* IE8 */;
}
define RotateCheckboxColumnHeaders function
var RotateCheckboxColumnHeaders = function (grid, headerHeight) {
// we use grid as context (if one have more as one table on tnhe page)
var trHead = $("thead:first tr", grid.hdiv);
var cm = grid.getGridParam("colModel");
$("thead:first tr th").height(headerHeight);
headerHeight = $("thead:first tr th").height();
for (var iCol = 0; iCol < cm.length; iCol++) {
var cmi = cm[iCol];
if (cmi.formatter === 'checkbox') {
// we must set width of column header div BEFOR adding class "rotate" to
// prevent text cutting based on the current column width
var headDiv = $("th:eq(" + iCol + ") div", trHead);
headDiv.width(headerHeight).addClass("rotate");
if (!$.browser.msie) {
if ($.browser.mozilla) {
headDiv.css("left", (cmi.width - headerHeight) / 2 + 3).css("bottom", 7);
}
else {
headDiv.css("left", (cmi.width - headerHeight) / 2);
}
}
else {
var ieVer = jQuery.browser.version.substr(0, 3);
// Internet Explorer
if (ieVer !== "6.0" && ieVer !== "7.0") {
headDiv.css("left", cmi.width / 2 - 4).css("bottom", headerHeight / 2);
$("span", headDiv).css("left", 0);
}
else {
headDiv.css("left", 3);
}
}
}
}
};
And include a call like RotateCheckboxColumnHeaders(grid, 110); after creating jqGrid.
