Converting JS DOM objects into HTML for IE

[interco]

OK, so it is kind of easy to dynamically create content using document.createElement() and appendChild() methods in Firefox for an xhtml document.

The thing is, IE does not act on them. I can only set innerHTML to something, IE seems to ignore appendChild(). This makes me to generate actual HTML from js.

This works in FF, not in IE:

  var mirenglon = document.createElement('tr');
  var fechacol = document.createElement('td');
  var letrecol = document.createElement('td');
  fechacol.setAttribute('id','columna_'+i);
  letrecol.setAttribute('id','renglon_'+i);
  fechacol.className='coursedata_date';
  letrecol.className='coursedata_fecha';
  mirenglon.appendChild(fechacol);
  mirenglon.appendChild(letrecol);    

  document.getElementById('coursecal_table').appendChild(mirenglon);
  document.getElementById('columna_'+i).innerHTML = fecha;
  document.getElementById('renglon_'+i).innerHTML = letrero;

So the questions are

1- Is there a way to make IE "understand" that I am actually trying to modify the document's DOM?

2- if not, is there a way to "convert" an object created by createElement() into HTML so that I can then update the page using innerHTML?

My mistake was that I was trying to append rows to a table object, instead of a tbody object. Now it works in both browsers.

I think I had the wrong question.
