It feels like maybe http://www.w3.org/TR/html5/tabular-data.html#dom-table-createcaption and http://www.w3.org/TR/html5/tabular-data.html#dom-table-deletecaption should be in the help here instead of the full table-link.  Or maybe it's supposed to be on the bigger sections? It's easy to click anyways. :-)
