Struct TableTheme 

pub struct TableTheme {

    pub header_bg: [u8; 4],
    pub header_fg: [u8; 4],
    pub row_bg: [u8; 4],
    pub row_stripe_bg: [u8; 4],
    pub selection_bg: [u8; 4],
    pub selection_fg: [u8; 4],
    pub border_color: [u8; 4],
    pub focus_ring_color: [u8; 4],
    pub cell_fg: [u8; 4],
    pub footer_bg: [u8; 4],
    pub footer_fg: [u8; 4],
    pub cell_padding_x: f32,
    pub cell_padding_y: f32,
    pub focus_radius: f32,
}

Colour tokens for the table widget, expressed as RGBA [u8; 4] arrays.

All colours use pre-multiplied-alpha conventions: a == 0 means fully transparent, a == 255 means fully opaque.

The defaults correspond to the COOLJAPAN Tokyo Night dark palette.

Fields

header_bg: [u8; 4]

Background colour of the column header row.

header_fg: [u8; 4]

Foreground (text) colour of the column header row.

row_bg: [u8; 4]

Background colour for data rows (even rows when zebra striping is off).

row_stripe_bg: [u8; 4]

Background colour for alternate (odd) rows in zebra-striping mode.

selection_bg: [u8; 4]

Background colour for the currently selected / highlighted row.

selection_fg: [u8; 4]

Foreground (text) colour for the currently selected row.

border_color: [u8; 4]

Border / grid-line colour between rows and columns.

focus_ring_color: [u8; 4]

Background colour of the cell that holds keyboard focus.

cell_fg: [u8; 4]

Default foreground (text) colour for all data cells.

footer_bg: [u8; 4]

Background colour for the footer (aggregate) row, if present.

footer_fg: [u8; 4]

Foreground (text) colour for the footer row.

cell_padding_x: f32

Cell horizontal padding derived from the spacing scale (logical pixels).

cell_padding_y: f32

Cell vertical padding derived from the spacing scale (logical pixels).

focus_radius: f32

Border radius for the focus ring (logical pixels).

Implementations

impl TableTheme

pub fn is_dark(&self) -> bool

Whether the colour scheme is perceived as dark (background luminance < 0.5).

Useful for selecting icon variants or blend modes in renderers.

pub fn effective_row_bg( &self, row_index: usize, is_selected: bool, zebra: bool, ) -> [u8; 4]

Apply an alpha blend: mix the theme’s selection_bg over row_bg for a given is_selected flag.

Returns the resulting RGBA colour for the row background.

Trait Implementations

impl Clone for TableTheme

fn clone(&self) -> TableTheme

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TableTheme

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TableTheme

fn default() -> Self

COOLJAPAN Tokyo Night dark defaults.

These values are hard-coded so the struct is usable without the theme-table feature. When the feature is enabled, prefer TableTheme::from_palette to derive colours from the active theme.

impl PartialEq for TableTheme

fn eq(&self, other: &TableTheme) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
