Function converts a gtsummary object to a flextable object. A user can use this function if they wish to add customized formatting available via the flextable functions. The flextable output is particularly useful when combined with R markdown with Word output, since the gt package does not support Word.
as_flex_table(x, include = everything(), return_calls = FALSE, ...)(gtsummary)
An object of class `"gtsummary"
Commands to include in output. Input may be a vector of
quoted or unquoted names. tidyselect and gtsummary select helper
functions are also accepted.
Default is everything().
Logical. Default is FALSE. If TRUE, the calls are returned
as a list of expressions.
Not used
A 'flextable' object
The as_flex_table() function supports bold and italic markdown syntax in column headers
and spanning headers ('**' and '_' only).
Text wrapped in double stars ('**bold**') will be made bold, and text between single
underscores ('_italic_') will be made italic.
No other markdown syntax is supported and the double-star and underscore cannot be combined.
To further style your table, you may convert the table to flextable with
as_flex_table(), then utilize any of the flextable functions.
