What is this?

This package is a unified (remark) plugin, specifically a remark-lint rule. Lint rules check markdown code style.

When should I use this?

You can use this package to check that table cells are padded consistently. Tables are a GFM feature enabled with remark-gfm.

Presets

This rule is included in the following presets:

Preset	Setting
remark-preset-lint-consistent	'consistent'
remark-preset-lint-markdown-style-guide	'padded'

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install remark-lint-table-cell-padding

In Deno with Skypack:

import remarkLintTableCellPadding from 'https://cdn.skypack.dev/remark-lint-table-cell-padding@4?dts'

In browsers with Skypack:

<script type="module">
  import remarkLintTableCellPadding from 'https://cdn.skypack.dev/remark-lint-table-cell-padding@4?min'
</script>

Use

On the API:

import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {remark} from 'remark'
import remarkLint from 'remark-lint'
import remarkLintTableCellPadding from 'remark-lint-table-cell-padding'

main()

async function main() {
  const file = await remark()
    .use(remarkLint)
    .use(remarkLintTableCellPadding)
    .process(await read('example.md'))

  console.error(reporter(file))
}

On the CLI:

remark --use remark-lint --use remark-lint-table-cell-padding example.md

On the CLI in a config file (here a package.json):

 …
 "remarkConfig": {
   "plugins": [
     …
     "remark-lint",
+    "remark-lint-table-cell-padding",
     …
   ]
 }
 …

API

This package exports no identifiers. The default export is remarkLintTableCellPadding.

unified().use(remarkLintTableCellPadding[, config])

This rule supports standard configuration that all remark lint rules accept (such as false to turn it off or [1, options] to configure it).

The following options (default: 'consistent') are accepted:

• 'padded' — prefer at least one space between pipes and content
• 'compact' — prefer zero spaces between pipes and content
• 'consistent' — detect the first used style and warn when further tables differ

Recommendation

It’s recommended to use at least one space between pipes and content for legibility of the markup ('padded').

Fix

remark-gfm formats all table cells as padded by default. Pass tableCellPadding: false to use a more compact style.

Examples

ok.md

When configured with 'padded'.

In

👉 Note: this example uses GFM (remark-gfm).

| A     | B     |
| ----- | ----- |
| Alpha | Bravo |

Out

No messages.

not-ok.md

When configured with 'padded'.

Too much padding isn’t good either:

| E     | F        |   G    |      H |
| :---- | -------- | :----: | -----: |
| Echo  | Foxtrot  |  Golf  |  Hotel |
