DataTables does not cope with colspan

DataTables does not cope with colspan

Thanks for this great library. Works a treat.

One quibble: DataTables does not seem to like colspans anywhere in the table. If the table has a td with a colspan attribute, you get:
"Uncaught TypeError: Cannot read property 'className' of undefined" (jquery.dataTables.js, line: #669)

I can understand that colspans are hard to deal with when sorting columns that go across a colspan. But sorting on other columns is theoretically possible, right?

Moreover, the above error also occurs when sorting is OFF. In other words the search-box/filter facility also breaks in the presence of a colspan.

I've been using v1.9.4 and the table below to reproduce this error:




Head1
Head2
Head3

    Not so much a bug, more a known limitation. Its unlikely in the near future support for colspan / rowspan in the tbody of the table will be added due to the complexity of dealing with hidden columns, column sorting, filtering, column filtering etc. It would likely require a lot of code to be added and significantly effect performance.

    Fair enough. I understand.
    So you wouldn't consider making it work when just the search-box is active and no other features?

    Not at this time. It would either be a core part, or not at all.

    Allan, so what you're telling me is that there's NO way your DataTables can provide a solution with a TR that has a TD with a colspan of any number?

    This really causes us a big problem.

    Can you suggest anything?

    Thanks, Allan

    No sorry - this is simply not possible in DataTables at the moment. Adding such support would add a huge amount of code and complexity to DataTables, and at the moment I have other priorities.
