====== creating dynamic tables ======

===== creating table elements =====
Use insertRow and insertCell after the initial table is created.
<code js>
var tbl = document.createElement('table');

var tr = tbl.insertRow(-1);
var td = tr.insertCell(-1);
</code>

===== setAttribute with rowspan or colspan isn't working in IE =====
You need to use a capital S like this:<code js>
td.setAttribute("rowSpan", "2");
td.setAttribute("colSpan", "2");
</code>
