Template:Nrow
|-
|{{{1}}}
This template gives the syntax for a table row containing parameter 1 if it is not empty, otherwise nothing. This allows optional rows in a table without causing empty rows causing empty space.
Usage
"{{nrow|x}}"
→ "
|- |x" [1] (as the linked ExpandTemplate page shows, there is a newline at start so that the row header will be interpreted correctly, but not at the end)
"{{nrow|}}"
→ "" [2]"{{nrow}}"
→ "
|- |{{{1}}}" [3]
