Template:Navbox with columns/testcases

This is a page for testing the sandbox version of Navbox with columns. Any changes to the template should be tested in the sandbox and verified here before going live.

colclass, colbodyclass, colNbodyclass tests

 * colclass ≡ listclass and should affect all colheaders/footers as well as all cols' contents (all "colbodies")?
 * colbodyclass should only affect all cols' contents (colbodies), not any colheaders/footers.
 * colNbodyclass should only affect col N's contents (its body).
