R: Set the widths of columns

cols_width {gt}

R Documentation

Set the widths of columns

Description

Manual specifications of column widths can be performed using the cols_width() function. We choose which columns get specific widths. This can be in units of pixels (easily set by use of the px() helper function), or, as percentages (where the pct() helper function is useful). Width assignments are supplied in ... through two-sided formulas, where the left-hand side defines the target columns and the right-hand side is a single dimension.

Usage

cols_width(.data, ..., .list = list2(...))

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.

...

Column width assignments

⁠<multiple expressions>⁠ // required (or, use .list)

Expressions for the assignment of column widths for the table columns in .data. Two-sided formulas (e.g, ⁠<LHS> ~ <RHS>⁠) can be used, where the left-hand side corresponds to selections of columns and the right-hand side evaluates to single-length character values in the form ⁠{##}px⁠ (i.e., pixel dimensions); the px() helper function is best used for this purpose. Column names should be enclosed in c(). The column-based select helpers starts_with(), ends_with(), contains(), matches(), and everything() can be used in the LHS. Subsequent expressions that operate on the columns assigned previously will result in overwriting column width values (both in the same cols_width() call and across separate calls). All other columns can be assigned a default width value by using everything() on the left-hand side.

.list

Alternative to ...

⁠<list of multiple expressions>⁠ // required (or, use ...)

Allows for the use of a list as an input alternative to ....

Details

Column widths can be set as absolute or relative values (with px and percentage values). Those columns not specified are treated as having variable width. The sizing behavior for column widths depends on the combination of value types, and, whether a table width has been set (which could, itself, be expressed as an absolute or relative value). Widths for the table and its container can be individually modified with the table.width and container.width arguments within tab_options()).

Value

An object of class gt_tbl.

Examples

Use select columns from the exibble dataset to create a gt table. We can specify the widths of columns with cols_width(). This is done with named arguments in ..., specifying the exact widths for table columns (using everything() at the end will capture all remaining columns).

exibble |>
  dplyr::select(
    num, char, date,
    datetime, row
  ) |>
  gt() |>
  cols_width(
    num ~ px(150),
    ends_with("r") ~ px(100),
    starts_with("date") ~ px(200),
    everything() ~ px(60)
  )
