The documentation site gained an AI / Agents section linking a
tabular skill (for LLM coding agents), the auto-generated
llms.txt, and a concatenated llms-full.txt,
mirroring the LLM-friendly documentation pattern.
col_spec(group_display = "header_row") now collapses
a single-member group to one flush-left row (the group value becomes the
row label, still carrying any cells_group_headers()
styling) instead of emitting a redundant header plus a lone indented
child, and no longer emits an empty header for a blank or
NA group value. Multi-member groups are unchanged.
figure() renders a figure (the “F” in TFL) to every
backend (RTF, LaTeX, PDF, HTML, DOCX, and Markdown), wrapping a ggplot,
a recorded base-R plot, a zero-argument drawing function, or a PNG / JPG
file in the same submission chrome as a table (titles, footnotes, page
header and footer). The image is placed in the body content-box by
halign and valign (both default to centred),
exact on the paged backends and approximate on the continuous ones. A
list input emits one figure per page, optionally driven by a
meta data frame whose columns become per-page
{token} values. On the continuous backends (HTML and
Markdown) a multi-page figure’s shared titles and footnotes render once
above the stacked plots; supplying meta switches to
per-page chrome. is_figure_spec() tests for the new spec,
and emit() writes it to a file. A figure’s titles,
footnotes, and page header / footer honour style() and the
preset() cosmetic knobs (fonts, colours, alignment,
padding) and the preset(spacing = ...) inter-section gaps,
just like a table; styling its (absent) body, headers, or subgroup is an
error. A drawing function that raises an error aborts with a clear
message naming the failing page. No new package dependency: plots
rasterise through base grDevices and ggplot2 (Suggests)
only when a ggplot is passed.
pivot_across() gained an aux argument
to bind auxiliary comparison columns (difference, hazard ratio, p-value)
from a second ARD, aligned 1:1 on the row_group key and
appended as trailing columns.
pivot_across()’s column argument now
accepts the reserved tokens .variable and
.stat to make an analysis variable a column band:
c(".variable", "<arm>") lays variables side by side
with statistics as rows, and c(".variable", ".stat")
spreads each statistic into its own column with the arm as a row stub.
Per-variable statistic / decimals resolve
inside each band.
pivot_across()’s decimals may now be a
list keyed by row_group values, for per-group precision in
one call.
preset(font_family = ...) generic chains
("mono" / "sans" / "serif") now
lead with the ubiquitous Microsoft Office face (Courier New / Arial /
Times New Roman) and keep the metric-compatible Liberation face as the
last fallback, so Word shows a font the reader actually has installed on
Windows / macOS instead of a phantom “Liberation Mono” in its font menu.
The faces are metric-compatible, so layout, line breaks, and decimal
alignment are unchanged. A bare font_family = "Courier New"
now also leads with Courier New (previously resolved led by Liberation
Mono). The package bundles no fonts; an arbitrary named face
("IBM Plex Mono", "Source Code Pro", etc.) is
emitted verbatim for the consuming application to resolve.
col_spec() gained a single indent argument
(an integer for a fixed level on every body row, or a column name for
per-row depth); the previous indent_by argument and the
usage = "indent" value were removed in favour of it. An
explicit indent on a
group_display = "header_row" host now suppresses the
section auto-indent, yielding a single rather than double indent.paginate() removed the no-op
panels = "auto"; panels is now a positive
integer.pivot_across() no longer pre-indents
stat_label with two leading spaces; indentation is applied
downstream by the renderer via col_spec(usage = "group") /
group_display, so a header_row stub no longer
double-indents.tabular_warning_<kind> class (input,
runtime, layout, fidelity)
mirroring the tabular_error_<kind> error taxonomy, so
warnings can be caught selectively; the former
tabular_warn_layout class was renamed to
tabular_warning_layout.col_spec() now warns when group_display or
group_skip is set on a non-group column (the knobs are
inert unless usage = "group").cols() / cols_apply() now restore a
column’s visibility and reset group_display on a later
call, and merge every column attribute field-completely (previously a
default value could not be merged back and some fields could be
dropped).emit() now centres decimal-aligned columns on every
backend instead of right-aligning the uniformly NBSP-padded block, so
the values sit under the centred column header (cross-backend
parity).emit() to DOCX now declares an in-class
<w:altName> fallback for each font, so a reader
missing the primary face substitutes a metric-compatible face in the
same class (mono stays mono) instead of panose-guessing to a serif. This
brings DOCX in line with the RTF (\*\falt) and PDF / LaTeX
(\IfFontExistsTF cascade) backends, which already declared
the same in-class fallback chain.emit() to HTML now applies per-cell body alignment
through a specificity-bumped .tabular-table td.text-* rule,
so decimal, centred and right-aligned columns actually render aligned;
previously the base .tabular-table td { text-align: left }
rule outranked the plain alignment class and every body cell silently
fell back to left.emit() to HTML now aligns the running page header and
footer to the table width via a centred fit-content container, instead
of spanning the full document width.emit() to HTML and Markdown no longer repeats a
subgroup() banner mid-table when a group is taller than one
estimated page. The continuous backends draw one banner per subgroup
value; the print-only page-break markers within a group are unchanged,
and the paged backends (RTF, LaTeX, DOCX) still repeat the banner on
every continuation page by design.emit() to PDF / LaTeX no longer renders the table wider
than the printable area: tabularray adds per-column separation outside
each column’s wd, so the column widths are now reduced by
that separation and the rendered table total matches the resolved width
(and the RTF / DOCX cell widths) instead of bleeding into the right
margin. (#27)emit() to PDF / LaTeX now renders column headers in
bold, matching the DOCX, RTF and HTML backends.emit() to PDF / LaTeX now sets the body font size after
\begin{document} (where it survives) and re-asserts it
inside the running header / footer, so an 8pt table no longer renders
its body or page chrome at the 10pt document-class default. (#27)emit() to PDF / LaTeX now tightens the gap between a
running page header and the title (and body to a running footer) to one
line via \headsep and \footskip, instead of
the wide document-class default.emit() to PDF / LaTeX no longer overflows a figure onto
a second page: the image is placed with flexible \vfill
glue rather than a fixed-height box that reconstructed to just over the
page height, so a multi-page figure (for example one Kaplan-Meier plot
per treatment arm) now fits one page per plot.emit() to RTF and DOCX no longer emits a phantom blank
page after each figure plot. The figure box reserves a line for the
closing paragraph every paged backend appends after the exact-height
image, RTF exits table context with \pard\par before the
next section break, and DOCX starts each continuation page with a
structural <w:pageBreakBefore/> instead of a
standalone page-break paragraph that stranded a blank page. A multi-page
figure driven by per-page meta also sizes each page’s image
box from that page’s interpolated footnotes, so a longer-footnote page
no longer overflows.emit() aborts with a clear
tabular_error_layout message when a figure’s titles and
footnotes alone exceed the printable height, instead of failing with an
opaque graphics-device error.emit() to RTF now leads the body font slot with the
first face of an explicit font_family stack instead of the
Linux-first default chain, and classes a mono stack
\fmodern (fixed pitch) the same way DOCX classes it
modern. A
font_family = c("Courier New", "Liberation Mono", "Courier")
request now renders as Courier New mono in Word instead of substituting
a serif, because the named primary face leads the font table rather than
being demoted to a \*\falt alternate.emit() to RTF now emits a section break only BETWEEN
panels (n-1 breaks for n panels) rather than after every panel, so a
single-panel table no longer ends with a trailing section break that
Word renders as a phantom blank page.emit() to RTF now reserves one line per running-header
row in \headery, so a multi-row page header (for example a
protocol row plus an analysis-set row) no longer bleeds back into the
body and tips the last table rows, or the table’s trailing paragraph,
onto a phantom second page.emit() now renders a zero-row empty-state page as a
normal table whose body is a single full-span, horizontally centred “no
data” message row, where the first data row would sit: the table chrome
(titles, column header) leads, the message follows in the body, and the
footnote trails immediately, all flowing compactly at the top of the
page with blank space below. The message is centred by each backend’s
native cell alignment on every backend (RTF, LaTeX, PDF, HTML, DOCX,
Markdown); it is no longer vertically centred or relocated into the page
margins. A natural-height message row plus trailing footnote cannot
overflow, so the recurring phantom-page bug stays fixed. A
subgroup(keep_empty = TRUE) empty crossing renders the same
way, as one message row in its own panel.emit() now closes a zero-row empty-state table’s data
region with the body bottom rule on every backend, so the “no data” page
carries the same closing rule a populated table does. The rule follows
the rules preset (a custom bottomrule width /
style / colour is honoured, and bottomrule = "none" drops
it) instead of being absent (RTF / DOCX) or a fixed default.emit() to PDF / LaTeX now wraps a table footnote to the
table width rather than overrunning it: the footnote minipage no longer
double-counts the column separation that the column widths already fold
in, so on a narrow table the footnote text stays within the table-width
footnote rule instead of spilling past it (and past the printable
width).figure() and paged-table pagination now size the body
box from the number of wrapped chrome lines a long title or footnote
actually occupies at the printable width, not the element count, so a
wrapped footnote no longer pushes content onto a second page on DOCX
(and any paged backend). Wrapping is computed by greedy word packing
against the font metrics. (#26)paginate() now collapses a zero-row table to a single
empty-state page; horizontal panels no longer multiply an
empty table into several identical blank pages.pivot_across() now resolves a keyed
statistic (e.g.
list(hierarchical = "{n} ({p}%)")) against each row’s real
ARD context on the hierarchical path, so a list keyed by
hierarchical no longer falls through to the bare
{n} default and silently drops the percent.pivot_across() now warns when the overall
label collides with an existing arm name, instead of silently merging
the pooled rows into that arm’s column.preset()’s decimal_metrics knob gained
"afm" (now the default), making decimal alignment
width-exact in proportional fonts via the bundled font metrics; Markdown
output keeps character padding.preset() gained an empty_text knob, a
house-style default for the zero-row message that a per-table
tabular(empty_text = ...) still overrides.preset(spacing = ...) now drives the blank lines around
a subgroup banner (the subgroup region) and around a
figure() title and footnote; the Markdown table title and
footnote gaps now follow the same knob.preset(width_mode = "window") now sizes auto columns
proportionally to their content width to fill the page, instead of
giving every column an equal share.subgroup() gained a keep_empty argument;
with keep_empty = TRUE a zero-N crossing is retained and
rendered as an empty-state page carrying its banner instead of being
dropped.subgroup() no longer errors on a zero-row input; the
table renders the empty-state placeholder once with no subgroup
banner.tabular() gained empty_text, the message
shown when a table has zero data rows (default “No data available to
report”). Zero-row tables now render the full page chrome and the column
headers with the message placed in the body, replacing the previous bare
“(no rows)” marker.First release. tabular renders pre-summarised clinical
tables and listings to RTF, LaTeX, HTML, PDF, and DOCX from one
immutable verb pipeline, with no external Java or SAS dependency. This
initial CRAN version consolidates the entire pre-release development
cycle: every feature and bug fix below was designed, implemented, and
tested before this first release.
Scope. This release covers tables and listings. Figure (graph) output is not yet supported and is the focus of the next release.
tabular() takes a pre-summarised wide data frame (one
input row is one display row) plus multi-line titles and
footnotes.cols() / col_spec() set per-column usage,
label, format, width, alignment (including decimal alignment via bundled
font metrics), visibility, NA text, per-row indent
(indent_by), and group display. cols() takes a
.default fallback col_spec(), and
cols_apply() applies one col_spec() to many
columns (by name or predicate), resolving a {.name} token
in a label to each matched column.headers() builds multi-level column-header bands with
passthrough leaves; sort_rows() sorts on hidden numeric
keys; subgroup() partitions with a {col}
banner template and optional per-page big_n.style() applies predicate-targeted cell styling through
the cells_*() location helpers; preset() /
set_preset() / get_preset() set cosmetic
defaults (fonts, colours, rules, padding, alignment, page chrome) per
table or per session, with reusable house styles via
style_template().footnote() attaches auto-numbered footnotes (letters,
numbers, or symbols) to any cell, column header, or title, deduped by
id and byte-identical across backends.paginate() does group-aware pagination with an
auto-computed per-page row budget; emit() writes the chosen
backend (creating parent directories with create_dir), and
as_grid() resolves the grid without I/O.inst/qualification/).md() and html().{expr} interpolation in static labels,
titles, footnotes, and header band labels, evaluated in the calling
environment at build time.preset(whitespace = "preserve"), the default).check_latex() reports LaTeX-package availability for
PDF output and prints the exact tlmgr_install() remedy for
anything missing — including a CTAN-mirror pin
(tinytex::tlmgr_repo("auto")) when an install stalls behind
the redirecting default mirror (commonly on Windows);
check_fonts() does the same for fonts, per backend.cdisc_saf_demo, cdisc_saf_ae,
cdisc_saf_aesocpt, cdisc_saf_vital,
cdisc_eff_resp, the BigN frames cdisc_saf_n /
cdisc_eff_n, and the long-format ARD companions
cdisc_saf_demo_ard / cdisc_saf_aesocpt_ard)
for examples and vignettes.
