[Plugin: Column-Matic] I see nothing

Edit or create a new post or page and past this in there:

[column width="180px" padding="10px"]please read[/column]
[column width="120px" padding="10px"]the <a href="https://plugins.twinpictures.de/plugins/column-matic/documentation/">documentation</a>[/column]
[end_columns]

https://plugins.twinpictures.de/plugins/column-matic/documentation/

That worked. Thanks.
