Plain HTML is not rendered inside tables
Description
Plain HTML is not rendered inside tables.
Example https://docs.gitlab.com/ee/ci/variables/where_variables_can_be_used.html#gitlab-ciyml-file
This is rendered correctly in GitLab https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/ci/variables/where_variables_can_be_used.md#gitlab-ciyml-file
I even tried Kramdown's hack to mix HTML, but it didn't work https://about.gitlab.com/handbook/product/technical-writing/markdown-guide/#mix-html--markdown-markup.
Steps to reproduce
Use the following snippet and see how Nanoc renders it:
| Definition | Can be expanded? | Expansion place | Description |
|--------------------------------------|-------------------|-----------------|--------------|
| `environment:url` | yes | GitLab | The variable expansion is made by GitLab's [internal variable expansion mechanism](#gitlab-internal-variable-expansion-mechanism).<ul><li>Supported: all variables defined for a job (project/group variables, variables from `.gitlab-ci.yml`, variables from triggers, variables from pipeline schedules)</li><li>Not supported: variables defined in Runner's `config.toml` and variables created in job's `script`</li></ul> |
