Transform deprecated styling attributes on HAST table cells to inline styles.
About
HAST is the abstract syntax (AST) tree representing HTML that rehype uses.
If you use remark to process Markdown as GitHub Flavored Markdown, you may find that your table cell elements end up with align
attributes.
However, align
on these elements was deprecated in HTML5: the suggestion is to use a style
attribute that sets text-align
, instead.
This matters because more recent syntaxes might altogether ignore align
or other deprecated styling attributes.
React, for example, does not support align
attributes; so if you try to transform Markdown to React elements, you'll lose your align
values.
(remark-react had to confront this issue.)
This simple utility transforms the following deprecated styling attributes on <td>
, <th>
, and <tr>
elements to equivalent inline styles:
align
valign
width
height
Installation
npm install @mapbox/hast-util-table-cell-style
Usage
const tableCellStyle = require('@mapbox/hast-util-table-cell-style');
// Use rehype to get an AST.
const transformed = tableCellStyle(ast);
Mutates the HAST AST you pass in, and returns it.
