You are getting this error:
You need to wrap
table.column( i ).header()
into jQuery to get the text, like this:Updated example:

Another option is to use
columns.name
then use thecolumn-selector
of{string}:name
to get the index. I added this to the example.Kevin
perfect i was trying position:name method too earlier. i have copy pasted your line in my testcase and it is not working. i am so sorry but i couldnt figure out what is wrong with that line. console.log('Using Position:name', table.column("Position:name").index()); my testcase http://live.datatables.net/toxanume/5/edit
You didn't add the
columns.name
option in your Datatables init code.Kevin
Hi kevin,
i have 60 columns, can I use any render function to initiate columns.name ? like get the name of the column, and init name for each of the columns.
thanks,

You have to define
columns.name
a initialization. You can create a variable that contains yourcolumns
definition before initialization then use that variable in the init code, for example:http://live.datatables.net/gigerava/3/edit
