ColReorder - Failed to execute 'insertBefore' on 'Node' : parameter 1 is not of type 'Node'

MichaelEC

Hi,

I've seen this question only posted a few times although nothing on any of those questions seem to match my exact issue and/or don't give too much to go on, apologies for posting this question again on here!

ColReorder has been working flawlessly on all my other tables (about 9 of them) although I can't seem to get it working on this one specific table - nothing jumps out as being different.

The exact error is

'Uncaught TypeError: Failed to execute 'insertBefore' on 'Node': parameter 1 is not of type 'Node'.'

Here's my DataTables code, very simple:

$(document).ready( function () {
    var oTable = $('#tbl_view_stocktake_details').DataTable(

{
            "paging": false,
            fixedHeader: true,
            colReorder: true,
});
});

Any ideas where I'm going wrong? If you need anything else, just ask, thanks!

Seems like the error has occurred in those threads due to have roespan or colspan in the header or having blank tr in the footer. In those threads the developer asked for test cases replicating the issue. If the thead and tfoot look ok for you then please post a link to your page or a test case so it can be debugged.

Genius, thanks a lot Kthorngren - it was the blank <tr></tr> in the <thead> tag!
