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”)
A data frame or data table to be rendered as a table.
digits
Number of significant digits to keep for numeric variables. When digits is an integer, tt() calls format_tt(x, digits = digits) before proceeding to draw the table. Note that this will apply all default argument values of format_tt(), such as replacing NA by "". Users who need more control can use the format_tt() function instead.
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:
A named list inserts a list with the name as superscript: list(“a” = list(“Hello World”))
A named list with positions inserts markers as superscripts inside table cells: list(“a” = list(i = 0:1, j = 2, text = “Hello World”))
width
Table or column width.
Single numeric value smaller than or equal to 1 determines the full table width, in proportion of line width.
Numeric vector of length equal to the number of columns in x determines the width of each column, in proportion of line width. If the sum of width exceeds 1, each element is divided by sum(width). This makes the table full-width with relative column sizes.
The table object has S4 slots which hold information about the structure of the table. This meta-data can be accessed with the usual @ accessor. In general, modifying the content of these slots is not recommended, but it can be useful to some developers, such as those who want to force print to a specific output format without calling print().
LaTeX preamble
When rendering Quarto and Rmarkdown documents, tinytable will populate the LaTeX preamble automatically with all the required packages. For standalone LaTeX packages, these commands should be inserted in the preamble:
Disable Quarto processing of cell content. Setting this global option to FALSE may lead to conflicts with some tinytable features, but it also allows use of markdown and Quarto-specific code in table cells, such as cross-references.
