Xajax, <table>, firefox and IE

[eluser]Unknown[/eluser]
Good morning to all.
I have an issue of compatibility between Firefox and IE.
I have a table layout which is predefined but its content is not.
On a button click, an xajax call is made to generate the table content.
The following code works great in Firefox but nothing in IE.
Following the code is the modification i tried with no sucess.

Table layout in view

Code:

<?php
  foreach ($Slist as $s){

  
  echo "<table id=\"tblSup".$s['Sup_Id']."EmpList\" class=\"hidden\">";
  echo "<tbody>";
  echo "test in view";

  echo "</tbody>";
  echo "</table>";

?&gt;

$s['Sup_Id'] is passed from the controller as $data and this part works fine.

Ajax function in controller

Code:

function __GenEmpTable($sup){

   $objResponse = new xajaxResponse();
    $this->load->database('....');
    $tbl ="<tr><th colspan=\"2\">List Employes</th></tr>";
            $query = $this->db->query("Select LName,FName from SupToEmp where Sup_ID = '".$sup."'");
            $x=0;
            foreach($query->result_array() as $emp){
              $tbl = $tbl. "<tr> <td width=\"80%\">&lt;input type=\"text\" readonly=\"true\" value=\"".$emp['FName']."\" id=\"fname".$sup."_".$x."\"/&gt;&lt;input type=\"text\" readonly=\"true\" value=\"".$emp['LName']."\" id=\"lname".$sup."_".$x."\"/&gt;</td>";
              $tbl = $tbl. "  <td>&lt;input type=\"checkbox\" size=\"3\" id=\"chkbx".$sup."_".$x."\"/&gt;</td></tr>";
              $x++;
              }

   $tblid ="tblSup".$sup."EmpList";
   $objResponse->Assign($tblid,"value", $tbl);
//    $objResponse->Assign("tstajaxId","innerHTML",$tblid);
    return $objResponse;
  }

This code works A1 in firefox but nothing in IE

i tried commenting all $tbl line and changing the Objresponse $tbl for some text like: "Listing"
still the same.
the commented $objResponse is a div for testing ajax, this one worked fine in both FF and IE.

It seems that IE does not process innerHTML into a table.

Hope someone knows more than me on this and can help me get this working.
Thanks.
