When attempting to rebuild a tablefield I get the following error in the DB log:

Notice: Undefined index: #ajax in ajax_form_callback() (line 395 of drupal/includes/ajax.inc).

My tablefield is currently 240 rows and 3 columns. I get this error when I change the # of columns to 4, as well as with an attempt to copy/paste in a complete 4-column data set. (running Drupal version 7.56)

If it does not happen with smaller tables it seems to be related to PHP limits.

If you use jQuery Update try https://www.drupal.org/node/2863761. If not try https://drupal.stackexchange.com/a/151270/19480.
