Removed in 2.0.0. tab_plot() drew a picture of the table as a ggpubr image. Use
tab_html(), tab_md() or tab_xl() to export the table itself, and forest_plot() for a
chart of the numbers – every estimate with its confidence interval, its significance and its
colour.
It was the only part of the package needing ggpubr, cowplot and gtable, whose dependency trees every user paid for; its display never matched the other backends'.
