Create a FlexTable from an rtables table

Usage

tt_to_flextable(
  tt,
  theme = theme_docx_default(tt),
  border = flextable::fp_border_default(width = 0.5),
  indent_size = NULL,
  titles_as_header = TRUE,
  footers_as_text = FALSE,
  counts_in_newline = FALSE,
  paginate = FALSE,
  lpp = NULL,
  cpp = NULL,
  ...,
  colwidths = propose_column_widths(matrix_form(tt, indent_rownames = TRUE)),
  tf_wrap = !is.null(cpp),
  max_width = cpp,
  total_width = 10
)

theme_docx_default(
  tt = NULL,
  font = "Arial",
  font_size = 9,
  bold = c("header", "content_rows", "label_rows"),
  bold_manual = NULL,
  border = flextable::fp_border_default(width = 0.5)
)

Arguments

tt

TableTree (or related class). A TableTree object representing a populated table.

theme

function(1). Defaults to theme_docx_default(tt). It expects a a theme function that is designed internally as a function of a flextable object and changes its layout and style. If set to NULL, it will produce a table similar to rtables default.

border

officer border object. Defaults to officer::fp_border(width = 0.5).

indent_size

integer(1). If NULL, the default indent size of the table (see matrix_form() indent_size) is used. To work with docx, any size is multiplied by 2 mm (5.67 pt) as default.

titles_as_header

logical(1). Defaults to TRUE for tt_to_flextable(), so the table is self-contained as it makes additional header rows for main_title() string and subtitles() character vector (one per element). FALSE is suggested for export_as_docx(). This adds titles and subtitles as a text paragraph above the table. Same style is applied.

footers_as_text

logical(1). Defaults to FALSE for tt_to_flextable(), so the table is self-contained with the flextable definition of footnotes. TRUE is used for export_as_docx() to add the footers as a new paragraph after the table. Same style is applied, but with a smaller font.

counts_in_newline

logical(1). Defaults to FALSE. In rtables text printing (formatters::toString()), the column counts, i.e. (N=xx), is always on a new line. We noticed that for docx exports could be necessary to have it on the same line.

paginate

logical(1). If you need .docx export and you use export_as_docx, we suggest relying on word pagination system. Cooperation between the two mechanisms is not guaranteed. This option splits tt in different "pages" as multiple flextables. Defaults to FALSE.

lpp

numeric. Maximum lines per page including (re)printed header and context rows

cpp

numeric(1) or NULL. Width (in characters) of the pages for horizontal pagination. NA (the default) indicates cpp should be inferred from the page size; NULL indicates no horizontal pagination should be done regardless of page size.

...

Passed on to methods or tabulation functions.

colwidths

numeric vector. Column widths for use with vertical pagination.

tf_wrap

logical(1). Should the texts for title, subtitle, and footnotes be wrapped?

max_width

integer(1), character(1) or NULL. Width that title and footer (including footnotes) materials should be word-wrapped to. If NULL, it is set to the current print width of the session (getOption("width")). If set to "auto", the width of the table (plus any table inset) is used. Ignored completely if tf_wrap is FALSE.

total_width

numeric(1). Total width in inches for the resulting flextable(s). Defaults to 10.

font

character(1). Defaults to "Arial". If the font is not vailable, flextable default is used.

font_size

integer(1). Positive integerish value that defaults to 9.

bold

character vector. It can be any combination of c("header", "content_rows", "label_rows"). The first one renders all column names bold (not topleft content). Second and third option use make_row_df() to render content or/and label rows as bold.

bold_manual

named list. List of indexes lists. See example for needed structure. Accepted groupings/names are c("header", "body").

Value

a flextable object.
