If you don’t provide any other bulk actions AND your users are infrequently deleting multiple rows at once, then allowing delete within the row may be a good option. You could show the delete option in each row or use some of the other techniques like a hover action to expose the option.

for example; a clickable “x” at the end of the row to delete it vs selecting the row and hitting a delete button.

desktop applications seem to opt of the later (in combination with an “add” button it creates a nice symmetrical interface), but web interface seem to swing both ways.

which is the best?
