API

This package exports no identifiers. It exports no additional TypeScript types. The default export is remarkLintNoTableIndentation.

`unified().use(remarkLintNoTableIndentation)`

Warn when GFM tables are indented.

Parameters

There are no options.

Returns

Transform (Transformer from unified).

Recommendation

There is no specific handling of indented tables (or anything else) in markdown. So it’s recommended to not indent tables and to turn this rule on.

Fix

remark-stringify with remark-gfm formats all tables without indent.

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-no-table-indentation@5, compatible with Node.js 16.
