<br>Original:
[code]function xDisplay(e,s)
{
  if(!(e=xGetElementById(e))) return null;
  if(e.style && xDef(e.style.display)) {
    if (xStr(s)) e.style.display = s;
    return e.style.display;
  }
  return null;
}[/code]
Alternative 2:
[code]function xDisplay(e,s)
{
  if ((e=xGetElementById(e)) && e.style && xDef(e.style.display)) {
    if (xStr(s)) {
      if (s == 'block' && e.nodeName) { /////// ???
        var ie = 'block';
        switch (e.nodeName.toLowerCase()) {
          case 'table': s = 'table'; break;
          case 'tr': s = 'table-row'; break;
          case 'td': case 'th': s = 'table-cell'; break;
          case 'li': s = 'list-item'; break;
          case 'caption': s = 'table-caption'; ie = 'inline'; break; // inline (IE6dn)
          case 'tbody': s = 'table-row-group'; ie = ''; break; // not rendered
          case 'thead': s = 'table-header-group'; ie = ''; break; // not rendered
          case 'tfoot': s = 'table-footer-group'; ie = ''; break; // not rendered
          case 'col': s = 'table-column'; break;
          case 'colgroup': s = 'table-column-group'; break;
        }
        try { e.style.display = s; }
        catch (e) { e.style.display = ie; }
      }
      else e.style.display = s;
    }
    return e.style.display;
  }
  return null;
