Dark theme for gt tables — gt_theme

A restrained dark theme. The background is a near-black instead of pure black, which avoids the smearing pure black causes on OLED screens. Column labels sit on a slightly raised band, rules are hairlines, and the body has no fills.

Usage

gt_theme_midnight(
  gt_object,
  accent = "#5B8DEF",
  density = c("comfortable", "compact", "social"),
  ...
)

Arguments

gt_object: A gt table object to modify.
accent: Character. A hex color for the row-group labels and the rule above the table. Defaults to "#5B8DEF".
density: Character. The type and padding scale. One of "comfortable", "compact", or "social". See Density. Defaults to "comfortable".
...: Additional arguments passed to gt::tab_options, applied last so they override anything the theme sets.

Value

Returns a modified gt table with the theme applied.

Details

Light text on a dark background reads as lighter weight than it is, so the theme opens up the line height to compensate.

Color scales on dark grounds

A green-to-red ramp built for white paper goes muddy on a near-black background, as its mid-tones collapse toward the background. Use pal_midnight with gt_color_ranks() instead.

Density

density sets the type and padding scale together. "comfortable" uses a 14px body with roomy rows, "compact" a 12px body with tight rows, and "social" a 17px body with generous rows and a larger title, at the scale gt_save_crop() and gt_social_crop() export at.
