Theme functions apply a complete visual style to a flextable in one call. Unlike ggplot2 themes, flextable themes are applied immediately to the existing table structure. Rows or columns added after the theme call are not formatted by the theme.
Apply the theme after all header, footer, and body rows have been added. To apply a theme automatically at print time (so it captures all rows), use set_flextable_defaults(post_process_html = theme_fun, ...) instead.

​
theme_vanilla()

External horizontal lines are black and 2 pt thick. Internal horizontal lines are 0.5 pt. Header text is bold. Text columns are left-aligned; numeric columns are right-aligned. 
theme_vanilla(x)

​
Example

ft <- flextable(head(airquality))
ft <- theme_vanilla(ft)
ft

​
theme_booktabs()

Publication-style theme based on the LaTeX booktabs package. Thick borders at the top and bottom of the header and at the bottom of the body. An optional thin line separates header rows. 
theme_booktabs(x, bold_header = FALSE, ...)
​
x
flextable
required
A flextable object.
​
bold_header

If TRUE, header text is rendered in bold.

​
Example

ft <- flextable(head(airquality))
ft <- theme_booktabs(ft)
ft

​
theme_box()

All cells have outer and inner borders. Header text is bold; footer text is italic. Text columns are left-aligned; numeric columns are right-aligned. 
theme_box(x)

​
theme_borderless()

All borders are removed. Header text is bold. Text columns are left-aligned; numeric columns are right-aligned.
