Style a markdown table with Bootstrap classes in Hugo

Inspired by this discussion, I wanted the ability to style a markdown table with Bootstrap table classes. In the past, I’ve accomplished this by defining the table in a data file, then building it with a shortcode.

While this works fine, it’s better for a different use case. I wanted something that meets the following criteria:

• The table is defined in markdown
• It lives in the content file, e.g. content/post/some-post.md
• It’s styled with Bootstrap table classes

After a bit of tinkering, here’s the shortcode I came up with. To use it, pass the markdown table between the shortcode, then pass the Bootstrap table classes as an argument.

Usage

{{< bootstrap-table "table table-dark table-striped table-bordered" >}}
| Animal  | Sounds |
|---------|--------|
| Cat     | Meow   |
| Dog     | Woof   |
| Cricket | Chirp  |
{{< /bootstrap-table >}}

Definition

{{ $htmlTable := .Inner | markdownify }}
{{ $class := .Get 0 }}
{{ $old := "<table>" }}
{{ $new := printf "<table class=\"%s\">" $class }}
{{ $htmlTable := replace $htmlTable $old $new }}
{{ $htmlTable | safeHTML }}

Output
