Datatables not showing

jj66

Sorry I'm new to jQuery. May I know what I'm doing wrong here:

Simplified version of RoR page:

http://live.datatables.net/ludiqoyi/1/

Console:

TypeError: col is undefined
if ( col.mData === i ) {

EDIT:

I'm using jquery-datatables-rails gem in Rails.

Thank you.

Test case is working okay for me when I include jQuery and DataTables: http://live.datatables.net/ludiqoyi/3/edit .

I found the mistake on the actual page: I have three col span.

Thank you.
