How Do I allow nullable columns/ Preventing DataTables warning: Requested unknown parameter x

addice1984

I am using datatables with server-side processing. However, I realize that I will always get

DataTables warning: table id=example2 - Requested unknown parameter 'x' for row 0. For more information about this error, please see http://datatables.net/tn/4

as long as one column is null.

How do I get about preventing getting this error?

Thanks

Did you have a read through the tech note linked to in the error message, and specifically the Resolution section?

Hi Allan,
Thanks for the input.
I guess this link would be closer to what I wanted.

http://datatables.net/reference/option/columns.render

Because I need the column for display and it may contain nullable value, I had done this:

{
"mData": "column1",
"render": function ( data, type, full, meta ) {
//console.log("Hello I am rendering...");
return data == null ? "" :data;
} },

That looks like it should work. Does it not? If not, can you link to a test page showing the issue please?

Yes Allan, it works, for my case. :-) The warning no longer pops up after I implemented it.
