Fail when adding new columns to tabular

[ariannab]

When adding columns to a tabular, for example, going from this:

\begin{tabular}{lr}
   \toprule
...

To this:

\begin{tabular}{lrrrrr}
   \toprule
...

Latexdiff will result in the following error:

! Misplaced \noalign.
         \toprule ->\noalign 
                    {\ifnum 0=`}\fi \@aboverulesep =\abovetopsep \global \@b...
            \DIFaddendFL \toprule

Which, in my best understanding, is due to the fact that \DIFaddendFL breaks the \toprule rules: \toprule can only follow a \begin{tabular} command. Hence, unfortunately, that \DIFaddendFL is an intruder that is not allowed to be there.

Do you happen to know any workaround for this? Thanks!
