I have the same problem as I noticed in the link https://datatables.net/forums/discussion/24834/getting-javascript-error-when-viewing-details-for-a-row , but I didn't see the salvation. What solvation can I give to the problem? When the right column of the main table is fixed when td.control click will open subtable and calculate the sizes of the fixed column. But there are errors in console and desktop. (console - cannot read property 'anCells' of undefined) and (desktop - the page is for processing all time).

but in my case I use ajax call
Can anyone help me, please?
