Yes!!! I use code in ZimbraWebmail....
By overloading ZmListView (Remove some unnecessary code for me)
But not override CreateHTMLHeader function
as below

function fgMasterFileListView(parent, className, posStyle, view, type, headerList, dropTgt) {

	if (arguments.length == 0) return;
	
	if (!headerList)
	   headerList = this._getHeaderList();
	//parent, className, posStyle, view, type, headerList, dropTgt
	className = className ? className : "DwtListView"; //"fgMasterFileListView"; 
	fgListView.call(this, parent, className, posStyle, fgController.MASTERFILE_VIEW, type, headerList); 

	this._listChangeListener = new AjxListener(this, this._changeListener);

}

fgMasterFileListView.prototype._getHeaderList =
function() {

	var headerList = new Array();
    //id, label, iconInfo, width, sortable, resizeable, visible, name
	headerList.push(new DwtListHeaderItem('id--c', fgMsg[fgMasterFile.A_IdentityID], null, fgMasterFile.DEFAULTWIDTH[fgMasterFile.A_IdentityID], fgMasterFile.A_Code, true, true, fgMasterFile.A_IdentityID));
	headerList.push(new DwtListHeaderItem('co--c', fgMsg[fgMasterFile.A_Code], null, fgMasterFile.DEFAULTWIDTH[fgMasterFile.A_Code], fgMasterFile.A_Code, true, true, fgMasterFile.A_Code));
	headerList.push(new DwtListHeaderItem('na--c', fgMsg[fgMasterFile.A_MyName], null, fgMasterFile.DEFAULTWIDTH[fgMasterFile.A_MyName], fgMasterFile.A_MyName, true, true, fgMasterFile.A_MyName));

	return headerList; 
}
