link Template:Navbox
The way this template is meant to work:
Usage is similar to {{tl|navbox}}, but with an additional distinction. Each row on the table can either be a "header", or it can have a label/data pair, or it can just be a data cell. These are mutually exclusive states so if you define a row to be both a header and a label/data pair, the label/data pair is overridden.
Note that if you want to insert an image elsewhere other than the top of the infobox, or insert other "freeform" data, using a row with just a "data" field allows for that sort of thing.
