Wrap text for tree column in dhtmlxgrid

Hi,
I am using dhtmlxgrid. In it my first column type is ‘tree’. I need to wrap text for that column.
I tried using
in cell in xml and ‘white-space:normal’ in style tag but didnt work.Can you please help me in fixing this issue.Here is my code
mygrid5 = new dhtmlXGridObject(‘mygrid_container5’);
mygrid5.setImagePath(“dhtmlx25/dhtmlxGrid/codebase/imgs/”);
mygrid5.setHeader(“Initiatives,Owner,Status,Actual,Target,Attainment,Comments”,[“text-align:right”,“text-align:center”,“text-align:center”,“text-align:center”,“text-align:center”,“text-align:center”,“text-align:center”,“text-align:center”]);
mygrid5.setInitWidths(“320,70,70,70,70,70,220”);
mygrid5.setColAlign(“left,left,right,right,right,right,left”);
mygrid5.setColTypes(“tree,ro,ed,ed,ed,ed,ed”);
mygrid5.setSkin(“light”);
//mygrid5.enableMultiline(true);
mygrid5.init();
mygrid5.attachEvent(“onXLS”, function() {
document.getElementById(‘cover’).style.display = ‘block’;
});
mygrid5.attachEvent(“onXLE”, function() {
document.getElementById(‘cover’).style.display = ‘none’;

});

mygrid5.enableHeaderMenu();
var URL = 'reportGenerate.do?strQuery=-600.15&actionPerformed=Download&strFileType=xml';
mygrid5.loadXML(URL);

And this is the style tag i have used to wrap the text for tree column
div.gridbox td span{
padding-left:5px;
white-space : normal;
}
Thanks in advance,
Pravallika.

Unfortunately it’s not available to wrap text in the tree column.
