get openxml raw code for Word
from a flextable object.
The function is particularly useful when you want
to generate flextable in a loop from a R Markdown document.
By default, the output is printed and is returned as a
character scalar.
When used inside an R Markdown document, chunk option results
must be set to 'asis'.
Arguments ft.align
, ft.split
and tab.cap.style
can be
specified also as knitr chunk options.
