Help:Lint errors/fostered

The fostered error is triggered when some content is in a table structure but not where it can be visible. Specifically, content in tables can only be present in table cells, table headings, and captions. Content inserted elsewhere gets moved before the table (content adopted by a foster parent, hence "fostering"). For example:

Here, " " is text where there cannot be any content, so it is adopted to the top of the table. This can be fixed by moving " " inside a table cell, table heading, or caption (by adding  or   or   markup before it). Or, if that content is indeed meant to be outside the table (as it renders in a browser), the markup should be fixed to reflect that intent.
