tt | R Documentation |
The tt
function renders a table in different formats with various styling options: HTML, Markdown, LaTeX, Word, PDF, PNG, or Typst. The table can be customized with additional functions:
style_tt()
: style fonts, colors, alignment, etc.
format_tt()
: format numbers, dates, strings, etc.
group_tt()
: row or column group labels.
theme_tt()
: apply a collection of transformations to a tinytable.
save_tt()
: save the table to a file or return the table as a string.
print()
: print to a specific format, ex: print(x, "latex")
tinytable
attempts to determine the appropriate way to print the table based on interactive use, RStudio availability, and output format in RMarkdown or Quarto documents. Users can call print(x, output="markdown")
to print the table in a specific format. Alternatively, they can set a global option: options("tinytable_print_output"="markdown")
tt(
x,
digits = get_option("tinytable_tt_digits", default = NULL),
caption = get_option("tinytable_tt_caption", default = NULL),
notes = get_option("tinytable_tt_notes", default = NULL),
width = get_option("tinytable_tt_width", default = NULL),
theme = get_option("tinytable_tt_theme", default = "default"),
rownames = get_option("tinytable_tt_rownames", default = FALSE),
escape = get_option("tinytable_tt_escape", default = FALSE),
...
)
x |
A data frame or data table to be rendered as a table. |
digits |
Number of significant digits to keep for numeric variables. When |
caption |
A string that will be used as the caption of the table. This argument should not be used in Quarto or Rmarkdown documents. In that context, please use the appropriate chunk options. |
notes |
Notes to append to the bottom of the table. This argument accepts several different inputs:
|
width |
Table or column width.
|
theme |
Function or string.
|
rownames |
Logical. If |
escape |
Logical. If |
... |
Additional arguments are ignored |
An object of class tt
representing the table.
The table object has S4 slots which hold information about the structure of the table. For example, the table@group_index_i
slot includes the row indices for grouping labels added by group_tt()
.
Warning: Relying on or modifying the contents of these slots is strongly discouraged. Their names and contents could change at any time, and the tinytable
developers do not consider changes to the internal structure of the output object to be a "breaking change" for versioning or changelog purposes.
.pdf
output requires a full LaTeX installation on the local computer.
.png
output requires the webshot2
package.
.html
self-contained files require the base64enc
package.
tinytable
uses the tabularray
package from your LaTeX distribution to draw tables. tabularray
, in turn, uses the special tblr
, talltblr
, and longtblr
environments.
When rendering a document from Quarto or Rmarkdown directly to PDF, tinytable
will populate the LaTeX preamble automatically with all the required packages. For standalone LaTeX documents, these commands should be inserted in the preamble manually:
Note: Your document will fail to compile to PDF in Quarto if you enable caching and you use tinytable due to missing LaTeX headers. To avoid this problem, set the option #| cache: false
for the chunk(s) where you use tinytable.
\usepackage{tabularray} \usepackage{float} \usepackage{graphicx} \usepackage{rotating} \usepackage[normalem]{ulem} \UseTblrLibrary{booktabs} \UseTblrLibrary{siunitx} \newcommand{\tinytableTabularrayUnderline}[1]{\underline{#1}} \newcommand{\tinytableTabularrayStrikeout}[1]{\sout{#1}} \NewTableCommand{\tinytableDefineColor}[3]{\definecolor{#1}{#2}{#3}}
Markdown and Word tables only support these styles: italic, bold, strikeout. The width
argument is also unavailable
Moreover, the style_tt()
function cannot be used to style headers inserted by the group_tt()
function;
instead, you should style the headers directly in the header definition using markdown syntax:
group_tt(i = list("*italic header*" = 2))
. These limitations are due to the fact that there is no markdown
syntax for the other options, and that we create Word documents by converting a markdown table to .docx
via the Pandoc software.
Options can be set with options()
and change the default behavior of tinytable. For example:
options(tinytable_tt_digits = 4) tt(head(iris))
You can set options in a script or via .Rprofile
. Note: be cautious with .Rprofile
settings as they may affect reproducibility.

The format_tt(quarto=TRUE)
argument enables Quarto data processing with some limitations:
The \QuartoMarkdownBase64{}
LaTeX macro may not process references and markdown as expected
Quarto processing may conflict with tinytable
styling/formatting
Options:
tinytable_quarto_disable_processing
: Disable Quarto cell processing
tinytable_print_rstudio_notebook
: Display tables "inline" or in "viewer" for RStudio notebooks
tinytable_quarto_figure
: Control Typst figure environment in Quarto
Example of Quarto-specific code in cells:
x <- data.frame(Math = "x^2^", Citation = "@Lovelace1842") fn <- function(z) sprintf("<span data-qmd='%s'></span>", z) tt(x) |> format_tt(i = 1, fn = fn)
