I had a problem in IE 6 when trying to insert a table using W3C DOM
techniques.
I found a solution and share it. :)

This would work in firefox 1.5 but not in IE 6.
The solution.... you have to explicitly insert the tr into a tbody element
and then the tbody into the table. So the function now becomes:
function insertTable() {
var table = document.create Element("table" );
table.setAttrib ute("id","table 2");
var tbody = document.create Element("tbody" ); // explicitly create a
tbody
var tr = document.create Element("tr");
var td = document.create Element("td");
td.appendChild( document.create TextNode("Some stuff in the cell"));
tr.appendChild( td);
tbody.appendChi ld(tr); // note this new line.
table.appendChi ld(tbody); // append tbody rather than tr
document.getEle mentById('outpu t').appendChild (table);
}
Hope this saves some else an hour or two. 11 2085

Nice, looks like IE is doing the correct thing, table rows should be
contained in a tbody.
The HTML-DOM interface insertRow should add this for you if it isn't there.

Since table rows are also part of table headers ('thead') and table
footers ('tfoot'), are you saying that IE refers to create child table row
elements for these nodes?
As long as you're into experiments, then here might be some more
experiments for you:
* See how the browsers do in adding MORE THAN ONE table header or table
footer element to a table node through calling DOM functions. Try more
than one table body while you're at it.
* Write more than one table header, table footer, and table body into a
table using validated HTML, see how the browser parses it by inspecting
the DOM tree thereafter. (Alternatively report the exceptions you find in
attempting certain calls.)
* Compose a validating simple HTML document in which you create a table
WITHOUT any section elements---no THEAD, no TBODY, no TFOOT----and just a
couple of rows each with a couple of cells (can be void of content).
Inspect the DOM hierarchy to see which browsers imposed section elements
(namely TBODY) into the table, and which rendered it just as you wrote it,
and which conformed to all specifications (HTML, ECMA-262::Javascript ,
DOM).
The results are a curiosity.

Proofreading Correction:
"...are you saying that IE refers to create..."
should read
"...are you saying that IE REFUSES to create..."

The HTML-DOM interface insertRow should add this for you if it isn't there.
I've discovered that the big difference is: IE inserts rows at the END
of the table, after the existing rows. Firefox inserts rows at the
BEGINNING of the table, before the existing rows.
If you have a <thead> and a <tbody> defined, then Firefox will insert
rows at the beginning of the <tbody>. Otherwise, it assumes that the
entire table is a <tbody> and inserts at the top.
Not sure which is the "proper" way to do it, but in this case, I'd say
the IE way makes more sense - when I want to add a row to an existing
table, I generally want it at the END.

That depends on how you call insertRow().

That's an implementation bug in some Mozilla browsers and Safari. It
was explained here:
<http://groups.google.c om/group/comp.lang.javas cript/browse_frm/thread/f1d06d29d2fd415 e/0ba38e911abbbcb 2>
As I said it is easy to fix for all browsers by using optional rowIndex
argument:
insertRow(-1)

Naturally. This is why it's a rather silly implementation bug.
Also note that IE will create tbody section for you automatically - but
not thead or tfoot. Some browsers will not do event that. The rule is:
if you plan to script your table later, mark up all three sections in
advance:
<table>
<thead></thead>
<tfoot></thead>
<tbody>
....
</tbody>
</table>
<table>
<thead></thead>
<tfoot></foot>
<tbody>
....
</tbody>
</table>
And the 3rd final attempt to make it right :-)
<table>
<thead></thead>
<tfoot></tfoot>
<tbody>
....
</tbody>
</table>

Since the HTMLTableElemen t::insertRow() method of W3C DOM Level 2 HTML
_requires_ that argument, that is, it is _not_ optional, how could
unexpected behavior due to omission of that argument possibly be
considered an "implementa tion bug"?
You are talking nonsense again.
