Given that deleting rows could be bad, I think that the delete selected rows icon should be placed as far away from other regularly used toolbar icons as possible. Currently I don't think the attribute table toolbar can be customised, so I can't do this myself. If the delete selected rows button is pushed, there is no confirm dialog and there is no undo function so the delete selected rows feature currently breaks interface guidelines that are in general use about minimising the potential for accidental use of a potentially destructive function. I would put the delete selected rows button to the right of the old field calculator button.
