My data table works fine in FF, but returns this error in IE. Looks like it has something to do with a hidden column.

I am using the latest version 1.7.3

    You've linked to the DataTables script, rather than your use of it :-), so it's a little difficult to be sure, but does your header include 7 TH elements - i.e. including the hidden ones? DataTables will hide then form you, but they must be in the header.

    Thanks Allan. Yes, there are seven TH elements, and it does work in both FF and Safari. I create the table in php and load it from a variable. I'm not sure what other clues I can give you. Thanks for your help...

    Can you link us to an example please (the link above is to DataTables - which we know where to get :-) ).

    Sure: http://dev.aircarealliance.org/resource-directory.

    Also, here is a clue from the console log: LOG: DataTables warning (table id = 'directory'): Unexpected number of TD elements. Expected 632 and got 474. DataTables 632 divided by the number of rows (79) is 8. Should be 7, no, since there are 7 columns? Also, 474 is 79 * 6, indicating that it's only getting six. Not sure how this is could be happening differently in IE vs. FF.

    Looking at the output, some cells are missing from columns that should be hidden, but some cells are missing from columns that shouldn't be hidden as well. That probably accounts for the mis-counting.

    Here are a couple of rows from the table raw output:

    [code]



    ACA
    Organization name for sorting
    Organization
    Service for filtering
    Service
    Contact
    Geography for filtering

    Ah - you've got a trailing comma on your aoColumns array: http://datatables.net/faqs#comma . IE (I would say correctly) treats the following array element as null - Firefox and friends delete it. Just remove the comma and it will go away.

    Good grief... I apologize, I've run into that before and I should have spotted it. Thanks for your help, and big thanks for the fantastic system.

    Best,

    Stephan
