cells_stub {gt}

Location helper for targeting cells in the table stub

Description

The cells_stub() function is used to target the table's stub cells and it is useful when applying a footnote with tab_footnote() or adding a custom style with tab_style(). The function is expressly used in each of those functions' locations argument. Here are several ways that a stub location might be available in a gt table: (1) through specification of a rowname_col in gt(), (2) by introducing a data frame with row names to gt() with rownames_to_stub = TRUE, or (3) by using summary_rows() or grand_summary_rows() with neither of the previous two conditions being true.

Usage

cells_stub(rows = everything())

Arguments

rows

Rows to target

⁠<row-targeting expression>⁠ // default: everything()

The rows to which targeting operations are constrained. The default everything() results in all rows in columns being formatted. Alternatively, we can supply a vector of row IDs within c(), a vector of row indices, or a select helper function. Examples of select helper functions include starts_with(), ends_with(), contains(), matches(), one_of(), num_range(), and everything(). We can also use expressions to filter down to the rows we need (e.g., ⁠[colname_1] > 100 & [colname_2] < 50⁠).

Value

A list object with the classes cells_stub and location_cells.

Overview of location helper functions

Location helper functions can be used to target cells with virtually any function that has a locations argument. Here is a listing of all of the location helper functions, with locations corresponding roughly from top to bottom of a table:

• cells_title(): targets the table title or the table subtitle depending on the value given to the groups argument ("title" or "subtitle").

• cells_stubhead(): targets the stubhead location, a cell of which is only available when there is a stub; a label in that location can be created by using the tab_stubhead() function.

• cells_column_spanners(): targets the spanner column labels with the spanners argument; spanner column labels appear above the column labels.

• cells_column_labels(): targets the column labels with its columns argument.

• cells_row_groups(): targets the row group labels in any available row groups using the groups argument.

• cells_stub(): targets row labels in the table stub using the rows argument.

• cells_body(): targets data cells in the table body using intersections of columns and rows.

• cells_summary(): targets summary cells in the table body using the groups argument and intersections of columns and rows.

• cells_grand_summary(): targets cells of the table's grand summary using intersections of columns and rows

• cells_stub_summary(): targets summary row labels in the table stub using the groups and rows arguments.

• cells_stub_grand_summary(): targets grand summary row labels in the table stub using the rows argument.

• cells_footnotes(): targets all footnotes in the table footer (cannot be used with tab_footnote()).

• cells_source_notes(): targets all source notes in the table footer (cannot be used with tab_footnote()).

When using any of the location helper functions with an appropriate function that has a locations argument (e.g., tab_style()), multiple locations can be targeted by enclosing several ⁠cells_*()⁠ helper functions in a list() (e.g., list(cells_body(), cells_grand_summary())).

Examples

Using a transformed version of the sza dataset, let's create a gt table. Color all of the month values in the table stub with tab_style(), using cells_stub() in locations.

sza |>
  dplyr::filter(latitude == 20 & tst <= "1000") |>
  dplyr::select(-latitude) |>
  dplyr::filter(!is.na(sza)) |>
  tidyr::spread(key = "tst", value = sza) |>
  gt(rowname_col = "month") |>
  sub_missing(missing_text = "") |>
  tab_style(
    style = list(
      cell_fill(color = "darkblue"),
      cell_text(color = "white")
      ),
    locations = cells_stub()
  )
