anchors, graphics and tables …

So … I updated a pin-out table as requested, deftly adjusted the colspans and rowspans to match the drawing I'd been given, and drew the lines. The results were as attached.  You can guess what happened next: we dropped a paragraph of text upstream of the table. The table moved obediently up, the graphic frame stayed where it was.

I thought that adding an anchored frame to hold the graphics frame might be the answer, but so far I haven't persuaded an anchored frame to cross the boundaries of the table cell :-{

Hints and tips welcome, as usual. I suppose it's no big deal to recreate the whole table as an .eps in Illustrator, if that's what it takes – just less elegant.
