-A table of items.
-
-Tables are used to arrange content in cells. Cells can contain arbitrary
-content, including multiple paragraphs and are specified in row-major order.
-For a hands-on explanation of all the ways you can use and customize tables
-in Typst, check out the [table guide](https://typst.app/docs/guides/table-guide/).
-
-Because tables are just grids with different defaults for some cell
-properties (notably `stroke` and `inset`), refer to the [grid
-documentation](https://typst.app/docs/reference/layout/grid/) for more information on how to size the table tracks
-and specify the cell appearance properties.
-
-If you are unsure whether you should be using a table or a grid, consider
-whether the content you are arranging semantically belongs together as a set
-of related data points or similar or whether you are just want to enhance
-your presentation by arranging unrelated content in a grid. In the former
-case, a table is the right choice, while in the latter case, a grid is more
-appropriate. Furthermore, Typst will annotate its output in the future such
-that screenreaders will announce content in `table` as tabular while a
-grid's content will be announced no different than multiple content blocks
-in the document flow.
-
-Note that, to override a particular cell's properties or apply show rules on
-table cells, you can use the [`table.cell`](https://typst.app/docs/reference/model/table/#definitions-cell) element. See its
-documentation for more information.
-
-Although the `table` and the `grid` share most properties, set and show
-rules on one of them do not affect the other.
-
-To give a table a caption and make it [referenceable](https://typst.app/docs/reference/model/ref/), put it into a
-[figure].
-
-# Example
-
-The example below demonstrates some of the most common table options.
-```typ
-#table(
-  columns: (1fr, auto, auto),
-  inset: 10pt,
-  align: horizon,
-  table.header(
-    [], [*Volume*], [*Parameters*],
-  ),
-  image("cylinder.svg"),
-  $ pi h (D^2 - d^2) / 4 $,
-  [
-    $h$: height \
-    $D$: outer radius \
-    $d$: inner radius
-  ],
-  image("tetrahedron.svg"),
-  $ sqrt(2) / 12 a^3 $,
-  [$a$: edge length]
-)
-```
-
-Much like with grids, you can use [`table.cell`](https://typst.app/docs/reference/model/table/#definitions-cell) to customize
-the appearance and the position of each cell.
-
-```typ
->>> #set page(width: auto)
->>> #set text(font: "IBM Plex Sans")
->>> #let gray = rgb("#565565")
->>>
-#set table(
-  stroke: none,
-  gutter: 0.2em,
-  fill: (x, y) =>
-    if x == 0 or y == 0 { gray },
-  inset: (right: 1.5em),
-)
-
-#show table.cell: it => {
-  if it.x == 0 or it.y == 0 {
-    set text(white)
-    strong(it)
-  } else if it.body == [] {
-    // Replace empty cells with 'N/A'
-    pad(..it.inset)[_N/A_]
-  } else {
-    it
-  }
-}
-
-#let a = table.cell(
-  fill: green.lighten(60%),
-)[A]
-#let b = table.cell(
-  fill: aqua.lighten(60%),
-)[B]
-
-#table(
-  columns: 4,
-  [], [Exam 1], [Exam 2], [Exam 3],
-
-  [John], [], a, [],
-  [Mary], [], a, a,
-  [Robert], b, a, b,
