That's the problem I came across while upgrading my code from DataTables 1+ to 2+.
When I use DataTables 1.10-1.13, it works perfectly well. I can changed content in every cell of a column I need:
table.cell(':eq('+i+')', 3).data("changed");
Test case with DataTables 1+ (works OK): https://live.datatables.net/hucifoba/1
But when I use DataTables 2+, I can changed only cells on the FIRST page of a column. Other pages remain unchanged. Moreover, I get a "Cannot read properties of undefined (reading 'row')" error.

Is it a bug? What should I do?

Not a bug - it is because DataTables 2 enables
deferRenderby default, but your code depends on the cell nodes being present to be selected (through the use of a jQuery selector - the:eq()).Using a row index selector works just fine.
So you could simply add
deferRender: falseand it will go back to the v1 behaviour, or you could look into updating the code to allow it to work with deferred rendering enabled. It will depend exactly on what you are doing for the best way to do that.Allan
Yes, deferRender: false did the job. Thanks for other options.
