Help:Lint errors/deletable-table-tag

This linter category has been added to assist editors in fixing wikitext and templates to ensure that their pages render correctly with a HTML5-based tool like RemexHTML (which will replace Tidy) and Parsoid.

Example:

In this example, Tidy will delete Table 2 above. But, RemexHTML and Parsoid will not delete that table. This will change how pages look. To prevent this, editors should fix the wikitext and remove Table 2. While the following row-tag need not be removed, we recommend removing it. Since the closing table tag is no longer needed, it should be removed as well.

Explanation
This linter category relates to a table being nested inside another table in a fosterable position (inside a  / |- tag, for example).

Since Tidy removes these tables right now, those table tags (and any styling associated with them) will not show up in the output. However, RemexHTML and Parsoid will preserve those table tags and will render two adjacent tables which might break rendering on pages. To preserve existing rendering with RemexHTML (which will replace Tidy) and Parsoid, this table tag wikitext should be removed. In cases where the wikitext comes from a template, Linter will also tell you what template produced that output, but you will have to investigate the template source to identify the relevant piece of template code that produces that table tag and fix it. See example of a template fix.
