I did it myself... For example it can be looking like follow:


<html>
<head>
</head>
<body>

<a href="#" onmousedown='TryDragStart()' onmousemove='DragStart()'>
    <table>
        <tr>
            <td>Row1</td>
            <td>Row2</td>
        </tr>
    </table>
</a>

</body>
</html>


<script language="javascript">

    document.onmouseup = DragStop;
    
    var dragTried = false;

    function TryDragStart()
    {
        dragTried = true;
    }
    
    function DragStop()
    {
        dragTried = false;
    }
    
    function DragStart()
    {
        if (dragTried)
        {
	        netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');
            
            var dragService = Components.classes["@mozilla.org/widget/dragservice;1"].getService(Components.interfaces.nsIDragService);
            var trans = Components.classes["@mozilla.org/widget/transferable;1"].createInstance(Components.interfaces.nsITransferable)
            trans.addDataFlavor("text/unicode");
            
            var textData = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
            textData.data = "Done!!!";
            
            trans.setTransferData("text/unicode", textData, textData.data.length * 2);
            
            var transArray = Components.classes["@mozilla.org/supports-array;1"].createInstance(Components.interfaces.nsISupportsArray);
            transArray.AppendElement(trans);
            
            dragService.invokeDragSession(dragService.TEXT_NODE, transArray, null, dragService.DRAGDROP_ACTION_COPY);
	    }
    }

</script>
