Does not *need*?  Objects implementing the HTMLTableRow interface simply do 
not have a “document” property in any known DOM implementation.

As a result, the property access results in “undefined” (if that), and this 
unsurprisingly completely clueless code, by the incorrigible “Danny” 
Googlodyte-wannabe haunting this newsgroup again, results in a *runtime 
error* (TypeError).

The only one of your suggestions that makes sense, with you knowing nothing 
about the table structure.  However, it should be

  var links = …;
  var lastLink = …;
