The rows of the TemplateData table in the documentation page take a lot of space even if the Default, Example and Auto value parameters are empty. This makes the documentation pages with lot of parameters unnecessarily long providing a lot of no relevant visual clutter and a huge vertical scroll. This can be seen for example in the Cite web template of the English Wikipedia, where most of the length of the page is irrelevant information such as:
Default
empty
Example
empty
Auto value
empty
It would be great to make these sections only visible in the documentation page when they are no empty.
