                    <th>Id</th>
                    <th>Account name</th>
                </tr>

function init_dlg(id, autoOpen, height, width, modal, fn_button1)
            {
                id.dialog({
                    autoOpen:autoOpen,
                    height:height,

                });
            }



function fn_ok()
            {
