A caption may be single or double spaced. Capitalization, punctuation, and layout of the captions must be consistent for all tables/figures in the series, though the placement of a caption for tables may differ from that of figures. The location of the caption must be the same for all tables/figures - a uniform distance from the top of the table/figure, or a uniform distance from the bottom of the table/figure. You may place the caption for tables above the tables and the caption for figures below the figures as long as all the tables are done the same and all figures are done the same.
NOTE: There must be a consistent number of blank lines between a Table or Figure and its caption.
