What is this?
This package checks table cell dividers are aligned.
Tables are a GFM feature enabled with remark-gfm
.
When should I use this?
You can use this package to check that tables are consistent.
Presets
This plugin is included in the following presets:
Preset | Options |
---|---|
remark-preset-lint-markdown-style-guide |
Install
This package is ESM only. In Node.js (version 16+), install with npm:
npm install remark-lint-table-pipe-alignment
In Deno with esm.sh
:
import remarkLintTablePipeAlignment from 'https://esm.sh/remark-lint-table-pipe-alignment@3'
In browsers with esm.sh
:
<script type="module">
import remarkLintTablePipeAlignment from 'https://esm.sh/remark-lint-table-pipe-alignment@3?bundle'
</script>
Use
On the API:
import remarkLint from 'remark-lint'
import remarkLintTablePipeAlignment from 'remark-lint-table-pipe-alignment'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'
const file = await read('example.md')
await unified()
.use(remarkParse)
.use(remarkLint)
.use(remarkLintTablePipeAlignment)
.use(remarkStringify)
.process(file)
console.error(reporter(file))
On the CLI:
remark --frail --use remark-lint --use remark-lint-table-pipe-alignment .
On the CLI in a config file (here a package.json
):
…
"remarkConfig": {
"plugins": [
…
"remark-lint",
+ "remark-lint-table-pipe-alignment",
…
]
}
…
API
This package exports no identifiers.
It exports no additional TypeScript types.
The default export is
remarkLintTablePipeAlignment
.
unified().use(remarkLintTablePipeAlignment)
Warn when GFM table cells are aligned inconsistently.
Parameters
There are no options.
Returns
Transform (Transformer
from unified
).
Recommendation
While aligning table dividers improves their legibility, it is somewhat hard to maintain manually, especially for tables with many rows.
Fix
remark-stringify
with
remark-gfm
aligns table cell dividers by default.
Pass tablePipeAlign: false
to use a more compact style.
Aligning perfectly in all cases is not possible because whether characters
look aligned or not depends on where the markup is shown.
Some characters (such as emoji or Chinese characters) show smaller or bigger
in different places.
You can pass a stringLength
function to remark-gfm
,
to align better for your use case,
in which case this rule must be turned off.

Compatibility
Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line,
remark-lint-table-pipe-alignment@3
,
compatible with Node.js 12.
