Error if more than one row of elements inside tag

norberto.ostallo

I've found a problem using DataTables. I'm using version 1.7 beta 5, but I had the same issue with v.1.6.2 and v.1.7 beta 3. I try to describe it here below.
Everything works fine in my table if I have only one row containing elements in the tag, but if I add a second row of elements (two tags inside the containing both elements) the javascript breaks reporting "a.aoColumns[b] is undefined" at line 2760:
[code]
oSettings.aoColumns[i].nTf = nTfs[i-iCorrector];
[/code]
Is this a known issue? Does DataTables have a limit of only one row of elements in a tag?

Hi norberto.ostallo,

Thanks for the information on this. The support that DataTables has for multiple rows in the header and the footer is fairly limited (in part because it would add a lot of code to support something which isn't used all that often). The key part where this is not supported in DataTables is in hidden columns.

Having said that, I believe it is wrong for DataTables to be breaking like this here, and I've just put a fix in for this to my development version of DataTables. This is going to shortly be released as 1.7 beta 6. It would be a great if you could give it a go and say if works for you :-)

Tested and perfectly working! :-)

Actually I've just found a little minor issue... :-)
By ignoring all the lines following the fist row it results than only the first one is properly decorated (CSS/jquety ui theme applied) and all the other have no theme.

Ah yes - I can see that that would happen. I'd suggest a workaround for this one - just add the required class names using jQuery ( $('#example tfoot th').addClass('whatever'); ) after DataTables has finished initialising. DataTables is only really expecting a single TH element in the footer for each column - it won't interfere with the other elements, which may need some additional processing such as this.

I will do as you suggest, thank you very much for the support!
