 ## Unreleased
 
+### Added
+- [#606](https://github.com/plotly/dash-table/pull/606) Add markdown support for table cells. Cells will be rendered as markdown if the column `presentation` is specified as `markdown`.
+    - Add highlight.js for syntax highlighting. If `window.hljs` is specified, that will be used for highlighting instead.
+
 ### Fixed
 - [#670](https://github.com/plotly/dash-table/pull/670) Fix a bug where `derived_filter_query_structure` was not getting updated properly
