github-remark-lint rule to warn when GFM table cells are aligned inconsistently.Contents
unified().use(remarkLintTablePipeAlignment)
What is this?
This package checks table cell dividers are aligned. Tables are a GFM feature enabled withremark-gfm
github-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 | | - | - | |

Warn when GFM table cells are aligned inconsistently.Parameters
There are no options.Returns
Transform (Transformer
from unified
github-unified-transformer).Recommendation
While aligning table dividers improves their legibility, it is somewhat hard to maintain manually, especially for tables with many rows.Fix
remark-stringify
github-remark-stringify with
remark-gfm
github-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.Examples

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@4
,
compatible with Node.js 16.Contribute
