Oh interesting. There's something buggy there all right. The diff isn't super wrong - you can indeed get from a.csv to b.csv by deleting column c and adding column d without any content - but it smells bad. You can force a better diff with daff --all a.csv b.csv but that won't help for real tables. Thanks for reporting the problem @Godsmith.
