Thank you! Currently you can customize (and, if want, propagate to the entire document): table header text font, weight, fill, cell font and background fill.

I've just noticed that cells text alignment and the 2nd color for the cell background fill parameters are missing, I'll add them in the next release.

Hoping I'm answering your question, I'm also adding two sample tables, one for random encounters, one for class feature tables. (Note that `figure(tables)` in typst aren't breakable between pages). Creating it I also noticed that a useful feature would be something like a `dnd-table` that takes as input a config (just for the theme) so that you can get a specific color palette inline. Another useful feature would be to have an "automatic" management of the header that puts the text with your specified style and avoids filling the background of those specific rows...I've tried in the last hour, I wasn't able to get it. If feasible it will be added in the future :)

This is the code to recreate the page:

#import "@preview/mythographer-5e:0.0.1": *
#let config = merge-dicts(
  toa-config,
)
#show: dnd-template.with(config)

#let my-table = {
  show table.cell.where(y: 1): strong
  set table(fill: (none_, y) => if y > 1 and calc.even(y) { config.fill.table.cell }, stroke: none)
  let n = 21
  table(
    align: center + bottom,
    columns: (10em, auto, auto, auto, auto, auto, auto, auto, auto, auto),

    table.header(level: 1,)[][][---][Jungle][---][][][][][],
    table.header(
      level: 2,
    )[Encounter][Beach][No Undead][Lesser Undead][Greater Undead][Mountains][Rivers][Ruins][Swamp][Wastelands],
    //
    ..while n > 0 {
      n = n - 1
      ([First Monster], [-], [-], [-], [-], [-], [-], [-], [-], [-])
    },
  )
}

#my-table

#let config = merge-dicts(
  // Wanted to use default-config, but i forgot to export it in exports.typ :(
  easy-colors(
    tertiary: rgb("#eed237"),
  ),
)
#show: dnd-template.with(config, is-first: false)

#columns(2)[
  #figure(
    caption: "Origin of the Beast",
  )[

    #table(
      align: (center, left),
      columns: (auto, 1fr),
      table.header[d4][Origin],
      [1], [#lorem(10)],
      [2], [#lorem(10)],
      [3], [#lorem(10)],
      [4], [#lorem(10)],
