I changed it to weekly view because we had a lot of events and I thought it might look better, and it messed up again. Switching back to the monthly view did not fix it.
I changed it back to the monthly view and it’s working now.
Yep, sorry. I should’ve looked at your table before replying; that demo does not apply to your issue.
jmarkj, The colspan issue was brought up at my site when an administrator had a table with a header that spanned all three rows and the table broke the javascript dependent navigation.
I’ve found an example of how spanning might be used when working with DataTables which you might find helpful. http://www.datatables.net/release-datatables/examples/basic_init/complex_header.html
