class="table-na" | N/A
Used in tables to show "N/A" in a cell with a nice background. This template adds a pipe (|) in the beginning, so if used in a cell with parameters modifying it, omit the pipe separating the modifiers and the cell contents. Instances where this may be a problem are in cells where you are using the width or style parameter.
Normal:
| cell one || cell two || cell three || {{n/a}}
Cell parameter:
| cell one || cell two || cell three ||width="25%" {{n/a}}
