Arguments

data

The gt table data object

⁠obj:<gt_tbl>⁠ // required

This is the gt table object that is commonly created through use of the gt() function.

table.width

Table width

The table width can be specified as a single-length character with units of pixels or as a percentage. If provided as a single-length numeric vector, it is assumed that the value is given in units of pixels. The px() and pct() helper functions can also be used to pass in numeric values and obtain values as pixel or percent units.

table.layout

The table-layout property

This is the value for the table-layout CSS style in the HTML output context. By default, this is "fixed" but another valid option is "auto".

table.align

Horizontal alignment of table

The table.align option lets us set the horizontal alignment of the table in its container. By default, this is "center". Other options are "left" and "right". This will automatically set table.margin.left and table.margin.right to the appropriate values.

table.margin.left, table.margin.right

Left and right table margins

The size of the margins on the left and right of the table within the container can be set with table.margin.left and table.margin.right. Can be specified as a single-length character with units of pixels or as a percentage. If provided as a single-length numeric vector, it is assumed that the value is given in units of pixels. The px() and pct() helper functions can also be used to pass in numeric values and obtain values as pixel or percent units. Using table.margin.left or table.margin.right will overwrite any values set by table.align.

table.background.color, heading.background.color, column_labels.background.color, row_group.background.color, stub.background.color, summary_row.background.color, grand_summary_row.background.color, footnotes.background.color, source_notes.background.color

These options govern background colors for the parent element table and the following child elements: heading, column_labels, row_group, stub, summary_row, grand_summary_row, footnotes, and source_notes. A color name or a hexadecimal color code should be provided.

table.additional_css

Additional CSS

The table.additional_css option can be used to supply an additional block of CSS rules to be applied after the automatically generated table CSS.

table.font.names

Pattern to combine column labels and units

The default pattern for combining column labels with any defined units for column labels. The pattern is initialized as "{1}, {2}", where "{1}" refers to the column label text and "{2}" is the text related to the associated units. When using cols_units(), there is the opportunity to provide a specific pattern that overrides the units pattern unit. Further to this, if specifying units directly in cols_label() (through the units syntax surrounded by "{{"/"}}") there is no need for a units pattern and any value here will be disregarded.

The option exists for providing keywords for certain types of footnote marks. The keyword "numbers" (the default, indicating that we want to use numeric marks). We can use lowercase "letters" or uppercase "LETTERS". There is the option for using a traditional symbol set where "standard" provides four symbols, and, "extended" adds two more symbols, making six.

footnotes.spec_ref, footnotes.spec_ftr

Specifications for formatting of footnote marks

container.width, container.height, container.padding.x, container.padding.y

Table container dimensions and padding

The width and height of the table's container, and, the vertical and horizontal padding of the table's container. The container width and height can be specified with units of pixels or as a percentage. The padding is to be specified as a length with units of pixels. If provided as a numeric value, it is assumed that the value is given in units of pixels. The px() and pct() helper functions can also be used to pass in numeric values and obtain values as pixel or percent units.

container.overflow.x, container.overflow.y

Table container overflow

Options to enable scrolling in the horizontal and vertical directions when the table content overflows the container dimensions. Using TRUE (the default for both) means that horizontal or vertical scrolling is enabled to view the entire table in those directions. With FALSE, the table may be clipped if the table width or height exceeds the container.width or container.height.

ihtml.active

Display interactive HTML table

The option for displaying an interactive version of an HTML table (rather than an otherwise 'static' table). This enables the use of controls for pagination, global search, filtering, and sorting. The individual features are controlled by the other ⁠table.*⁠ options. By default, the pagination (ihtml.use_pagination) and sorting (ihtml.use_sorting) features are enabled. The ihtml.active option, however, is FALSE by default.

ihtml.use_pagination, ihtml.use_pagination_info

Use pagination

For interactive HTML output, the option for using pagination controls (below the table body) can be controlled with ihtml.use_pagination. By default, this is TRUE and it will allow the use to page through table content. The informational display text regarding the current page can be set with ihtml.use_pagination_info (which is TRUE by default).

ihtml.use_sorting

Provide column sorting controls

For interactive HTML output, the option to provide controls for sorting column values. By default, this is TRUE.

ihtml.use_search

Provide a global search field

For interactive HTML output, an option that places a search field for globally filtering rows to the requested content. By default, this is FALSE.

ihtml.use_filters

Display filtering fields

For interactive HTML output, this places search fields below each column header and allows for filtering by column. By default, this is FALSE.

ihtml.use_resizers

Allow column resizing

For interactive HTML output, this allows for interactive resizing of columns. By default, this is FALSE.

ihtml.use_highlight

Enable row highlighting on hover

For interactive HTML output, this highlights individual rows upon hover. By default, this is FALSE.

ihtml.use_compact_mode

Use compact mode

For interactive HTML output, an option to reduce vertical padding and thus make the table consume less vertical space. By default, this is FALSE.

ihtml.use_text_wrapping

Use text wrapping

For interactive HTML output, an option to control text wrapping. By default (TRUE), text will be wrapped to multiple lines; if FALSE, text will be truncated to a single line.

ihtml.use_page_size_select, ihtml.page_size_default, ihtml.page_size_values

Change page size properties

For interactive HTML output, ihtml.use_page_size_select provides the option to display a dropdown menu for the number of rows to show per page of data. By default, this is the vector c(10, 25, 50, 100) which corresponds to options for 10, 25, 50, and 100 rows of data per page. To modify these page-size options, provide a numeric vector to ihtml.page_size_values. The default page size (initially set as 10) can be modified with ihtml.page_size_default and this works whether or not ihtml.use_page_size_select is set to TRUE.

ihtml.pagination_type

Change pagination mode

For interactive HTML output and when using pagination, one of three options for presentation pagination controls. The default is "numbers", where a series of page-number buttons is presented along with 'previous' and 'next' buttons. The "jump" option provides an input field with a stepper for the page number. With "simple", only the 'previous' and 'next' buttons are displayed.

ihtml.height

Height of interactive HTML table

Height of the table in pixels. Defaults to "auto" for automatic sizing.

page.orientation

Set RTF page orientation

For RTF output, this provides an two options for page orientation: "portrait" (the default) and "landscape".

page.numbering

Enable RTF page numbering

Within RTF output, should page numbering be displayed? By default, this is set to FALSE but if TRUE then page numbering text will be added to the document header.

page.header.use_tbl_headings

Place table headings in RTF page header

If TRUE then RTF output tables will migrate all table headings (including the table title and all column labels) to the page header. This page header content will repeat across pages. By default, this is FALSE.

page.footer.use_tbl_notes

Place table footer in RTF page footer

If TRUE then RTF output tables will migrate all table footer content (this includes footnotes and source notes) to the page footer. This page footer content will repeat across pages. By default, this is FALSE.

page.width, page.height

Set RTF page dimensions

The page width and height in the standard portrait orientation. This is for RTF table output and the default values (in inches) are ⁠8.5in⁠ and ⁠11.0in⁠.

page.margin.left, page.margin.right, page.margin.top, page.margin.bottom

Set RTF page margins

For RTF table output, these options correspond to the left, right, top, and bottom page margins. The default values for each of these is ⁠1.0in⁠.

page.header.height, page.footer.height

Set RTF page header and footer distances

The heights of the page header and footer for RTF table outputs. Default values for both are ⁠0.5in⁠.

quarto.use_bootstrap, quarto.disable_processing

Modify Quarto properties

When rendering a gt table with Quarto, the table can undergo transformations to support advanced Quarto features. Setting quarto.use_bootstrap to TRUE (FALSE by default) will allow Quarto to add Bootstrap classes to the table, allowing those styles to permeate the table. Quarto performs other alterations as well but they can all be deactivated with quarto.disable_processing = TRUE (this option is FALSE by default).

Value

An object of class gt_tbl.

Examples

Use select columns from the exibble dataset to create a gt table with a number of table parts added (using functions like summary_rows(), grand_summary_rows(), and more). We can use this gt object going forward to demo some of tab_options() features.

tab_1 <-
  exibble |>
  dplyr::select(-c(fctr, date, time, datetime)) |>
  gt(
    rowname_col = "row",
    groupname_col = "group"
  ) |>
  tab_header(
    title = md("Data listing from **exibble**"),
    subtitle = md("`exibble` is an R dataset")
  ) |>
  fmt_number(columns = num) |>
  fmt_currency(columns = currency) |>

tab_1

We can modify the table width to be set as '100%'. In effect, this spans the table to entirely fill the content width area. This is done with the table.width option and we take advantage of the pct() helper function.

tab_1 |> tab_options(table.width = pct(100))

With the table.background.color option, we can modify the table's background color. Here, we want that to be "lightcyan".

tab_1 |> tab_options(table.background.color = "lightcyan")

We have footnotes residing in the footer section of tab_1. By default, each footnote takes up a new line of text. This can be changed with the footnotes.multiline option. Using FALSE with that means that all footnotes will be placed into one continuous span of text. Speaking of footnotes, we can change the 'marks' used to identify them. Here, we'll use letters as the marks for footnote references (instead of the default, which is numbers). This is accomplished with the footnotes.marks option, and we are going to supply the letters vector to that.

tab_1 |>
  tab_options(
    footnotes.multiline = FALSE,
    footnotes.marks = letters
  )

The data rows of a table typically take up the most physical space but we have some control over the extent of that. With the data_row.padding option, it's possible to modify the top and bottom padding of data rows. We'll do just that in the following example, reducing the padding to a value of 5 px (note that we are using the px() helper function here).

tab_1 |> tab_options(data_row.padding = px(5))

The size of the title and the subtitle text in the header of the table can be altered with the heading.title.font.size and heading.subtitle.font.size options. Here, we'll use the "small" keyword as a value for both options.

tab_1 |>
  tab_options(
    heading.title.font.size = "small",
    heading.subtitle.font.size = "small"
  )
