You are getting this error:

Uncaught TypeError: table.column(...).header(...).text is not a function

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

var title = $( table.column( i ).header() ).text();

Updated example:

Another option is to use columns.name then use the column-selector of {string}:name to get the index. I added this to the example.

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.

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 your columns definition before initialization then use that variable in the init code, for example:
