short of encoding the data and having it decode in javascript, no. and anyone running your page will have access to the decoding key and/or algorithm, in which case it's not really secure either.

opss sorry i didn't see it. thanks :)

see my fix/comment: http://datatables.net/forums/discussion/6591/cleanup-fixedheader

Just send the unique URL in its own column, keep that column invisible, and use it for whatever you want with the fnRowCallback. You could add the anchor tag wrapping to any other column's content within the callback function instead of within the JSON itself. Be mindful of the limitations of markup itself. For example, foo is not valid. Which isn't to say you can't make the whole row clickable; just not with an anchor tag. But I'm getting ahead of myself: what is the specific use case?

http://datatables.net/release-datatables/examples/data_sources/ajax.html "DataTables expects an object with an array called "aaData" with the data source." This should fix your ajax/JSON: [code] { aaData: [ { "label":"9-hydroxy-risperidone", "x":0, "y":1.5051929155586775E-4, "z":"42.0", "cond":"treatment", "selected":0, "term":"9-hydroxy-risperidone", "star":0, "conceptId":"13697" }, ... (more data) [/code]

-- edit -- nevermind

Just a correction on the size of the local data file The local data file is approximately 16 MB with approximately 250K( not 21K records as reported earlier) records. Regards Joson

Thanks this works fine.

Hi Again, sorry for ma question, i have found that instead of sending aaData: [{column_name:column_value}] i need to send only aaData: [{column_value}] I will try it and send notice if it solve my problem. Sorry again, hope that it doesn't waste your time so much. Lukas
