. The confusing percentage column
has been deleted. The “Output” column has been deleted, along with the rows corresponding to the
output sub-categories; since most of the values in these sub-categories are small, they are relatively
unimportant and could if necessary be discussed in the text

graphs or explanatory text are preferable; have a table to which the interested reader
can refer, but don't rely on a table to convey essential information.
Captions and Labels
Captions and labels should be informative. Though it is common for captions to be
