cells_stub: Location helper for targeting cells in the table stub

Description

cells_stub() 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())

Value

A list object with the classes cells_stub and location_cells.

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 (e.g. starts_with(), ends_with(), contains(), matches(), 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).

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::pivot_wider(
    names_from = "tst",
    values_from = sza,
    names_sort = TRUE
  ) |>
  gt(rowname_col = "month") |>
  sub_missing(missing_text = "") |>
  tab_style(
    style = list(
      cell_fill(color = "darkblue"),
      cell_text(color = "white")
      ),
    locations = cells_stub()
  )
